GLOWING PINK FLYING SQUIRRELS: Biofluorescence Revealed

Southern Flying Squirrels, Glaucomys volans, glowing hot pink on their underbellies when illuminated by a 365 nm UV flashlight, in a rare phenomenon known as biofluroescence

I awoke last night at midnight to flashes of light from a motion sensor floodlight on our deck. I wasn’t thinking of prowlers, because I suspected the flashes of light were triggered by Southern Flying Squirrels coming to visit for the sunflower seeds I had tossed out just before going to bed.

I crept downstairs and carefully opened the sliding door, letting in frigid February air. The deck light came on briefly, enough that I could see the tiny squirrels dashing up through an opening in the deck around a huge Northern Red Oak. Each squirrel would come up, grab a sunflower seed, then dash down the tree trunk out of sight. This happened so fast that I couldn’t see how many squirrels there were, though at one point I saw three. There may have been more. On this night they were nervous and did not stop long enough for any photos.

We’ve had Southern Flying Squirrels at our home in Michigan each winter, and I’ve photographed them at night several times using incandescent lights on the deck. They made for good photographs, with their gray-brown fur and a cuteness factor of huge bulging eyes and little pink lips, but their coloration was subtle to my eyes and essentially no different from most mammals, which are colored for camouflage rather than display.

Then scientific knowledge suddenly changed. About four years ago a Wisconsin forestry professor, Dr. Jonathan Martin at Northland College, was in the woods at night looking up toward the forest canopy with an ultraviolet flashlight for lichens and other fluorescing lifeforms, when a hot pink missile glided overhead. He identified this as a Northern Flying Squirrel, and its normally white belly lit up hot pink in ultraviolet light. He found this astounding, and asked a colleague to investigate flying squirrel skins in a couple of museum collections to see if the phenomenon could be confirmed. It turned out that in those collections, the bellies of all three species of North American flying squirrels–Southern, Northern, and Humboldt’s Flying Squirrels–glowed bright pink under UV light. Even specimens over 100 years old. Male and female, young and old, they nearly all glowed.

Since we have easy access to flying squirrels at our home in Central Michigan, I decided to observe this phenomenon for myself. I obtained a 365 nm UV flashlight that is powerful enough to look almost into the treetops and began looking at these squirrels on nights they chose to come to our feeding station. They don’t come every night, but when they do I often get up in the middle of the night to observe and try to photograph them. It isn’t easy to photograph little nervous squirrels by a relatively dim (to our eyes) UV light, but I’ve had some success represented by the pictures here.

Why do flying squirrels glow? That is still unknown. What is known is that at dusk, dark, and dawn, the air is bathed in proportionately more ultraviolet light and far less light from the visible spectrum than in daytime. This UV light–when converted to visible light by fluorescence–makes the flying squirrels more visible to each other. This is even more true when snow blankets the forest, since snow reflects UV light. It also appears that flying squirrels’ eyes, unlike ours, can see into the UV spectrum, so this ability may also be involved.

Again: why do they use biofluorescence and UV light at night? There are a couple of possibilities that spring to mind. Based upon the three flying squirrels I observed on that recent February night, I think it’s possible that the squirrels use their bubblegum pink undersides to keep track of each other at night. These squirrels are highly social, with reports of 25 to 50 Southern Flying Squirrels roosting communally in a hollow tree. So why wouldn’t they follow each other to food sources? Some of my pictures show them sitting side by side, dining quietly together on the sunflower seeds I put out. They seem to enjoy a more peaceable kingdom among their kind than do the daytime Eastern Gray Squirrels and American Red Squirrels we also get in Central Michigan. Feeding together also means more big eyes to look for predators–much as goldfinches and other songbirds feed communally as a strategy to detect hawks.

There is another tantalizing possibility for the pink color. Three large owls that also live in this region–Barred, Barn, and Great Horned Owls–also have bellies that fluoresce hot pink under UV light, though their coverings are feathers rather than fur. These owls are the chief predators of flying squirrels. Do the flying squirrels mimic the owls to fool the predacious birds into thinking they are seeing other owls when in the air? Maybe. I find this possible. The fluorescing fur is mostly on the belly and undertail of the squirrels, with just a minor hint of color change on the back and virtually none on the tail. Once a flying squirrel lands on a tree trunk, its back and tail make it almost invisible to predators because the glowing belly is nearly hidden.

Alternatively, perhaps the owls are mimicking the flying squirrels, fooling the little squirrels into thinking they are seeing others of their own kind. This would allow the owls to silently approach the flying squirrels and suddenly grab the little creatures.

Or perhaps all three of these mechanisms are in play: bubblegum pink signals the presence of flying squirrels to each other, but also both disguises them from owls and identifies them to owls, if any of that makes sense. Coevolution at work.

Biofluorescence also extends to the Virginia Opossum in this region, but is apparently unknown in other mammals here. It turns out the phenomenon is new enough that the chemical and physical mechanism is still unknown. I suspect this will be studied in coming years, with possible applications for industry. Or not. Knowledge is its own reward.

I will be watching these creatures over the coming weeks and years, both with and without the assistance of UV light. The mysteries of nature are an ingrained part of my life and I find observations and photography endlessly fascinating.

Brooks Range Expedition: Alaska 1984

The story of our 1984 journey to Gates of the Arctic National Park in the Brooks Range of far north Alaska in words and in photographs. Below the story there are many more photographs that you can click on to enlarge and also see photo captions.

“You guys might want to get out of the tent … there’s a Grizzly out here.” Denis Davis startled us out of our perpetual twilight dreams with that simple statement, and we’ve rarely gotten dressed so fast. The Griz was several hundred yards away on the Arctic tundra and was steadily traveling up the treeless valley. If it smelled us–which it probably did given that we had been backpacking for a week–it didn’t stop to check us out or even look our way. For that we were grateful, given that we had no protection in the era before real bear spray.

This two-week backpacking trip in Alaska’s Brooks Range originated in Denis’ Christmas card for 1983, in which he suggested several possible adventure trips for the coming year to a number of his friends. We were the only ones who responded, and we liked the idea of backpacking in Gates of the Arctic National Park, which was at that time a newly minted national park.

We began planning for the trip in conjunction with Denis and his wife at the time, Elaine. We needed to carefully consider every aspect of our equipment for weight and usefulness. I needed camera gear, including a 500mm lens for wildlife, a macro lens for wildflowers, and a wide-angle lens for landscapes, plus 25 rolls of Kodachrome film. Tents at the time were limited, and we needed a tent strong enough to withstand possible snow, so we brought the legendary North Face VE-25, a favorite of Mount Everest expeditions, but which weighed 12 pounds! Karen brought a hiking staff that was actually a beaver-chewed stick from the Adirondacks; she had to check it on the cross-country flight because the gate attendant said it looked like a weapon. Our clothing was in the pre-fleece era and included items Karen sewed from Frostline kits. We had jeans, army surplus wool pants, wool shirts and sweaters, long underwear, rain-resistant pants, and Frostline parkas. We also each had an insulated Frostline vest; these would also serve as pillows. Plus stocking caps and Frostline mittens and heavy wool socks for hiking. Water-resistant hiking boots were essential to combat the wet tundra and snow.

Considering food, we had to keep it light. Karen used our dehydrator to dry all sorts of precooked meals, not all successfully. Dried shredded cheddar cheese was crunchy and tasty, but melted away needed fats. For lunches we ate Pemmican Bars, which were an early protein bar from the 1980s. For breakfast and dinner we cooked on a Svea stove that ran on white gas. Our simple meals included a commercial beef stroganoff, rice and beans and dried cheese and chocolate. Breakfast always included hot drinks: our standing joke on this mosquitoey trip was that when a mosquito would land in the hot chocolate, we would fish it out, but any leftover mosquito legs would just go down the hatch. We lost weight on this trip because our calorie intake couldn’t possibly keep up with our exertions.

At the start of the trip, Lee’s backpack weighed 78 lbs, with Karen’s about 59. Karen had a full bright orange daypack lashed on top of her backpack; she sewed it from a Frostline kit.

After all our preparations, the time for travel came in late July, 1984. We flew from Syracuse, New York to Anchorage, Alaska. There we boarded a flight to Fairbanks, and then a smaller plane to Bettles, a tiny Alaskan bush town on the Koyukuk River. This is where we did our final planning and packing for the trip, with our gear splayed across the runway’s edge. We talked to some guys who were heading into another part of the Brooks Range who had long rifles with them for protection and hunting; we felt quite naked by comparison. But at the time, it was illegal for hikers to carry a gun in a national park, so that wasn’t even a possibility for us.

With our packs finally stuffed, we walked to the office of the bush plane to give them our final itinerary. We were to be dropped off by float plane at a small lake in the western part of Gates of the Arctic National Park, then we would hike for about two weeks and 50 miles through Arctic tundra, following rivers. Our biggest challenge would be a climb over unnamed mountains, hoping we could get to the crest, then down the steep cliffs on the north side. This was all uncertain, because it was possible no human being had ever traveled this route over the mountains and the available topographic map was not detailed enough to confirm cliff locations. This was real, raw wilderness in the extreme. If all went well, we would follow a drainage from the mountains, hiking north until we reached Kurupa Lake, where we would be picked up by float plane.

We finally shouldered our heavy packs and walked to the Koyukuk River, where our float plane magic carpet awaited. This was a Canadian-made bush plane, a De Havilland Beaver, that was and is the workhorse of the far north. We took off from the river–our first experience on a float plane–and followed the river west for a ways, with us watching for Moose among the Black Spruce trees along the river. Eventually the pilot left the river and turned the plane north, taking us over turquoise tarns and rugged, sharp peaks where the trees eventually dwindled to none, leaving us over a treeless tundra. We came to a broad opening in the mountains where several lakes shimmered, and one of those was our destination. The pilot descended and made a smooth landing on the lake, then taxied over to the shore. We didn’t even get our feet wet while unloading our gear. After confirming our final meeting point for a rendezvous two weeks later, the pilot taxied into the center of the lake, then took off with a roar, leaving us feeling lonely on the vast tundra. The pilot had been instructed to pick us up at Kurupa Lake, but if we weren’t there, then he would look for us at our drop-off lake in case we couldn’t make it over the mountains.

Two things happened within minutes: we found a distinct fresh Gray Wolf track in the wet soil between tussocks, and mosquitoes descended upon us in Biblical multitudes. We were in the Alaska Wilderness!

After a few minutes of gazing out over the lake, we pulled out our mosquito head nets, shouldered our lead-filled packs, and set out on a two-week journey through one of the wildest places in North America. We consulted our topographic maps, then headed over a ridge that looked down over a long valley stretching toward a line of mountains in the distance. Our route would take us down the valley along an unnamed river past unnamed mountains. 

Our trip took place at the warmest time of year in the Brooks Range, with temperatures hovering above 70°F. At our feet, arctic wildflowers bloomed in profusion–most of them hugging the ground to avoid the drying winds–while along the river Arctic Fireweed was vivid. In this warm weather, the clouds of mosquitoes were legendary. To cope we wore head nets, plus applications of DEET-containing Jungle Juice. Karen had sewn the placket gaps above our sleeve cuffs shut to keep the bugs out. But we discovered that they could still bite through our jeans, so we ended up with a lot of itchy welts. During the first two days of hiking along this long valley, we saw no large charismatic wildlife, so we focused upon cool birds we had never before seen, such as a Wandering Tattler on its nest site, an American Golden-Plover, and a Gray-Crowned Rosy Finch.

We set up our first campsite on the lower flanks of a mountain high above the valley. This was northern Alaska during the height of summer, so the sun barely set, making the inside of our yellow tent look like perpetual dim daylight all through the long night. We thought it might be hard to sleep in these conditions, but we were so worn out from hiking with heavy packs that sleep was not a problem. As we gazed up the valley the next morning we could see where we would camp the next night; an expansive view.

Grizzly Bears were always on our minds, but not enough to keep us from sleeping. Without bear spray and without guns, our defense lay in our numbers–with four of us, that should work as a deterrent against daytime attacks. At night, we needed to protect our food supply from bears, but there was no place on the open tundra to hang our food. Each night we took our packs and placed them together about 100 yards downwind from our tents. Atop the packs we placed our cooking pots with stones in them, so a raid on the packs would alert us with noise. We also had little mesh bags made by Karen containing mothballs that we hoped would cover up the scent of food, or at least serve as a repellent. While hiking, the mothballs were triple bagged to contain the strong fumes.

The next day we hiked further along the river, coming upon a spot where there was enough shade from the mountains that river ice several feet thick had not yet melted; it resembled glacial ice, with its aqua-blue color. Later, we were setting up camp when we heard the blowing and galloping of a mammal coming our way. It was our first Caribou, and it appeared to be running in terror. But nothing was chasing it, and it was possible that there was a parasitic larva called a nosebot driving it crazy. Or maybe it was the ever-present mosquitoes.

The third day out, we left our broad, open valley and began ascending a steeper route into the mountains. This was the drainage we hoped to take over a high pass at the northern crest of the range. As the day wore on, the cloud cover increased and there was a noticeable chill in the air. We set up our tents high in a cirque, with sharp peaks rising around us, then finished our camp chores and wriggled into our sleeping bags. A drizzle began, followed by rain, then silence.

When we awoke the next morning, there was about four inches of fresh snow on the tents. It was cold, and we decided it would be too treacherous to make our climb over the pass in these conditions. So we took a snow day, mostly napping and reading inside our tents, waiting for the weather to pass.

The following morning the weather had again changed, with sunny blue skies appearing between clouds still hanging in. We decided this was our day to face the biggest challenge of the trip, so we loaded up and headed straight up the snowy steep and rocky slope toward the pass. When we reached the pass, the view straight north to the Arctic Plain greeted us. The wind was blowing hard over the pass, so we took shelter against a rock buttress and ate lunch. Then Denis and Lee split up to try to find a safe route down from the pass. Denis went to the east and Lee ascended to the west, each looking carefully at our chances. When we got back together, Denis said his side of the pass was not feasible, but Lee decided we had a good chance of making it if we carefully went in his direction. It involved climbing higher, then going sidehill in snow while hugging a cliff above a steep, snow-covered dropoff. If we went far enough, we would reach a scree slope leading all the way down to the valley at a steep angle.

Lee turned to Karen, who gets nervous with exposed heights, and said “You’re going to have to be brave.” She was, and we carefully inched along the cliff face without mishap, then began our steep descent. The scree slope was snow covered, but we forcefully stuck our legs through the snow to the soft rocky debris (almost like a fine gravel dune) and felt almost entirely safe. When we made it to the bottom, it was with a sense of triumph and relief that the most difficult part of the journey was behind us. We celebrated by making a no bake boxed cheesecake chilled in the snow, and all was right with the world.

The bad weather closed in again the next morning, and we hiked down the length of a lake with wet snowflakes steadily falling. Very briefly the mosquitoes were too chilled to move. The mountains were gleaming with their coat of fresh snow. We climbed out of the valley into some foothills. Then, while eating lunch we saw movement in the distance. Binoculars revealed one of the most amazing sights of our lives: thousands of Caribou traveling across the rocky terrain! We changed our route to intercept the herd and over the following days we watched and photographed them extensively, burning the sight into our memories as well as on film.

We camped that night on a ridge in the path of the Caribou, and all night we could hear the clicking of tendons in their ankles as they walked past our tents. It is a fascinating phenomenon, and apparently it serves to keep herds together as they travel–even in the clouds and fog of the mountains they can hear each other enough to stay together. The Caribou traveled well-worn paths along mountain slopes and through wildflower meadows. There were bull Caribou with huge antlers, as well as females with smaller antlers and young of the year racing around. These were part of the Western Arctic Caribou Herd, which migrates twice yearly between the calving grounds on the Arctic Plain and the wintering grounds south of the Brooks Range. When we saw them, they were gathered together in a huge group, but not yet beginning their fall migration south. Our days among the Caribou were wonderful, as we saw them crossing streams and silhouetted against snowy mountains.

On another morning about this time in the trip we saw our first Grizzly Bear; fortunately it didn’t pay us any attention. It was astounding to see how large it was and how prominent was the hump on its back. One advantage of hiking in the tundra is you can see bears from a long way away. We still remember Denis and Elaine talking about being first on the scene of a near-tragedy in Glacier National Park. A family of four had been hiking together when they surprised a Grizzly in the forest. It attacked, and had one child’s head in its gaping mouth when the father jumped on its back. The bear broke the man’s arms but then called off the attack. But enough about scary bear stories. 

Our packs were now a bit lighter from the food we had consumed, and our still-young bodies gained strength as the days wore on. One day Denis proposed we go off on our own and he and Elaine do the same. That sounded good, and we ventured into the Kurupa Hills. Our highlight was seeing a young Dall Sheep lying on the tundra, and later seeing some adults crossing a talus slope. At our campsite we enjoyed watching an Alaska Marmot, though not-so-much an Arctic Ground Squirrel who chewed through one of our plastic water containers. During the second half of the trip we saw Peregrine Falcons, which were truly rare in the lower 48 during the 1980s because of the effects of DDT, as well as a Long-tailed Duck on a tundra pond, and Long-tailed and Parasitic Jaegers, which flew at us aggressively when we got too close to their nesting grounds.

Hiking further, we approached our destination, Kurupa Lake. Denis didn’t tell us at the time, but later said an early oil prospector’s report described the “herds of Grizzly Bears” at Kurupa Lake. Fortunately, we encountered no herds, but we did see a second Grizzly Bear on the other side of the lake, where it paused to furiously dig up an Arctic Ground Squirrel’s burrow. It is astounding how fast those massive muscles and claws allow a Grizzly to dig. We assumed it got the squirrel. 

We stayed two nights at our last campsite, giving the bush plane plenty of time to retrieve us. While we waited, Karen and Denis both fished, each catching a Lake Trout and observing Arctic Char. Denis released his fish, but Karen was determined to eat ours. So we cleaned the fish and boiled it, tossing the carcass into the lake to reduce the scent. It was good, but the scent from the cooking would have clung to our wool clothing, undoubtedly acting as a lure for a bear. Fortunately we didn’t attract any bears to camp.

There was always a chance the plane would not appear on our pickup date; if fog or other bad weather delayed previous days’ retrievals, people would be picked up in order and they would get to us as soon as possible. We were getting low on white gas and food and speculated that if we were delayed by days we would be eating raw fish.

We were entranced by the whole experience, and Lee could have turned around and stayed in the wilderness for another two weeks if we had the time. Alas, work called and we needed to return. On our last day we needed to pack early and have our gear ready to go. In the afternoon we heard the whine of a plane approaching, and it turned and descended to our lake. The pilot had instructed us to leave a tent up so he could spot us along this large lake. As soon as we knew the pilot had spotted us, the tent was quickly collapsed and we hoisted our packs to trudge down to the shore, then loaded our gear onto the float plane. When we took off, it signaled the end to one of the signature experiences of our lives.

The photographs below show a map of our route, final packing on the runway in Bettles, our flight north through the mountains, and our first moments on the arctic tundra. Click on any of the pictures for a larger view and more information.

As we hiked across the tundra with our heavy packs, the Arctic revealed itself in beautiful wildflowers, distant views, Caribou antlers, fast streams, and campsites with glorious views.

We identified and photographed wildflowers and lichens and ferns that we had never before seen. The tundra plants are short, hugging the ground to stay out of the wind and take advantage of the warmth near the ground; most of the wildflowers are pollinated by flies, since bees are scarce in the Arctic.

When we reached the end of a long valley and several days of warm temperatures, our route next led us into the mountains. After setting up camp, rain turned to snow. After a rest day, we climbed steeply up into the mountains, not knowing if we could cross the range here. It turned out that we could, although there were challenges of negotiating ice and snow and a steep scree slope.

After the steep mountain crossing we hiked down a long valley in rain and snow, passing alpine lakes and crossing a stream. Here our wildlife sightings began in earnest, with Grizzly Bears, Caribou, Dall Sheep, and birds we had never seen before. Seeing thousands of Caribou was a highlight of our lives.

After all our time in the wildest wilderness we had ever experienced, it was time for a float plane to pick us up at Kurupa Lake on the north side of Gates of the Arctic National Park. We arrived two days early and spent the extra time fishing and hiking. Alas, we heard the plane overhead and quickly packed up, ending one of the premier adventures of our lives.

Wilderness and adventure in far off places would lure us to distant locations and backpacking trips during the ensuing decades, but nothing would be quite the challenge as this trip to the Brooks Range. Looking back now, nearly four decades later, we both think of it as a highlight of our lives.

October at Staircase in Olympic National Park

The pleasant white noise of water running over rocks in the North Fork Skokomish River blends with the occasional warning clicks of a concerned Pacific Wren and the wind rushing through the needles and leaves of conifers and maples. Low angle sunlight occasionally shines through the brilliant orange leaves of Bigleaf Maples along the river’s edge. A family of American Dippers walks underwater through the rapids, searching for insect larvae. A cousin of the robin, the Varied Thrush, has migrated in for the winter and individuals are foraging through the mossy forest.

Each time I come to Staircase, named for an actual wooden staircase that a military expedition built to climb over rugged nearby cliffs, I am enchanted by the exotic lifeforms that populate this rainforest. There are the Icicle Mosses that drape the limbs of maples and dead conifers so thickly that I wonder how the branches can support the weight of this wet mass of moss.

There are Dog Vomit Slime Molds that we encounter in the woods. These are neither plant nor animal and normally live their lives as single cells, but when something triggers them, these cells come together to act as a larger organism that actually oozes through the forest in a search for food.

There is the Methuselah’s Beard, the longest lichen in the world, hanging like Spanish Moss from the limbs of riverside maples and firs. It is the Methuselah’s Beard that attracts me to frequently return to Staircase. There is one special Bigleaf Maple that the lichen has enjoyed living on for years, to the point that much of the tree looks decorated in fake spider webs for Halloween. I thought I was the only photographer attracted to this tree, but it turns out there are many others; on one recent trip two photographers came by while I was photographing and said that they make pilgrimages to photograph this tree every autumn. This lichen species is extremely sensitive to air pollution and is used by scientists as an indicator of poor quality air; it has been declining across much of its range around the world for this very reason. But at this location on the Olympic Peninsula, bathed in moisture coming off the Pacific Ocean, the air is clean and wonderful. The lichen thinks so as well, and looks to be content living here.

Focus on the Inner Mind

While visiting the lovely little Yashiro Japanese Garden in Olympia, Washington, I at first didn’t know what to photograph. The garden was pretty, but I wasn’t overwhelmed with a desire to take pictures. I decided to stay longer and work at it, freeing my mind from preconceived notions of what might make strong photographs here. Eventually the details captured me, and I chose to take a zen approach to my photography, focusing narrowly on detail and letting the background float away into a wash of color.

Exploring the stunning formations of WHITE POCKET

Twisting and swirling, the red rock follows the random paths of a wild dream, then skirts a dome of white Navajo Sandstone cracked into nearly perfect polygonal plates, enchanting under a perfect sapphire sky. All of it originated 190 million years ago with a Jurassic sand dune that became saturated with groundwater, then experienced a sudden disruption–perhaps by an earthquake–that suddenly contorted the whole wet jumble while it had been hardening into sandstone. Incredible beauty resulted from this chaos.

Our time is short for exploring before the short period of golden light near sunset, so we walk around quickly to get a feeling for the whole area, which is about a square mile in size. An outfitter got us here and we have about 20 hours from mid-afternoon today to mid-morning the next day to explore and photograph before we have to leave. We are on our own, except that the outfitter provides dinner, a tent, and breakfast the next morning. The reason we came with a touring company is that we don’t have a rugged 4-WD vehicle to get us through the March mud quagmires and deep sand traps along the access roads. A tow out would cost $2,000 and is not covered by AAA. So here we are.

I once worked for the Bureau of Land Management on the Arizona Strip, a part of Arizona between the Grand Canyon and the Utah state line. This is an arid landscape that includes pockets of incredible beauty, such as Paria Canyon, The Wave, and White Pocket. When I was there with BLM in 1977, I was working as a writer and pen-and-ink illustrator for a book of wildflowers (still in print 43 years later!), but White Pocket was virtually unknown at the time, except for some ranchers and probably a handful of government employees. I certainly didn’t know about it and even if I did, my big Chrysler at the time couldn’t have dreamed of getting there. The name White Pocket originated from the desert term “pocket” which referred to a rock depression that can hold water–an important feature for cattle ranching and desert travelers. At that time the world hadn’t yet discovered much of the stunning beauty of red rock country. While at BLM, I heard the geologist for our district remark to my boss that he thought it was better in the desert when it was all considered a wasteland, and environmental regulations didn’t need to be followed. Fortunately, times have changed.

We spend the hours before dark exploring and photographing in great light, then walk back to camp for a meal of barbecued salmon or chicken or steak (another value in contracting with an outfitter!), then we venture back out into the contorted lands for hours of night photography. We return to camp sometime after midnight, then get up at 4 a.m. for dawn photography, so not much sleep. We stay until afternoon, delayed for a couple of hours by a vehicle problem, and we don’t mind the delay in the least, because it gives us more time to explore this place torn from time.

The photographs here give the visual story of White Pocket, which is the most stunning desert location we have visited.

Rather than give you directions and maps and more cautions, I will refer you to three good websites that cover all that information. Be advised that there have been discussions at the Bureau of Land Management about requiring a permit so the area does not become overused, so make sure you check with them about current rules and regulations (and road conditions) before you attempt traveling to White Pocket.

ADVENTURING TO A NEWFOUNDLAND OUTPORT

Fishing Stages and Colorful Homes in Francois Outport during a S
Fishing stages and colorful homes in Francois during a snowstorm

The first leg of the journey was the drive to Burgeo, a fishing village accessed by Route 480 from the Trans-Canada Highway near Stephenville. The wild and beautiful landscape was covered with deep snow, and the conifers were magically encrusted with a thick layer of hard snow so that, in places, they looked like snow elves. We kept our eyes alert for Woodland Caribou, but didn’t see any on the drive. When we reached Burgeo, we stayed at a small motel that would be convenient for catching a ferry the next morning.

We packed what we would need for the trip in two suitcases and left the rest in the car, since we couldn’t take a car on the Marine Voyager ferry. These communities have no roads and no cars, so all that is needed is a foot ferry, albeit one that can carry enough cargo to meet a small community’s daily needs. We walked up the ramp on the ice-covered boat, then descended into a room for the passengers. Comfortable seats, round portholes, and a soap opera on the television – what more could we hope for? We paid our fee of $6 per passenger, which was clearly subsidized by the government, and settled in for our sailing along the coast.

There were only a couple of other passengers, and they lived in the villages of Grey River and Francois (a French name Newfoundlandized to “Fran-Sway.”) We were invited up to the bridge for a front-row seat and visit with the captain, who was a lifelong resident of Francois. One of the other passengers, a younger man named Cody who owned a fishing boat, introduced himself to us as well. He was also a lifelong resident of Francois and he told us about the community and what he liked about living there. 

Hesitantly we asked the captain if he thought the ferry would be running two days later when we wanted to make our return trip, which would give us enough time to drive back to St. John’s and catch our flight back to the USA. He said this was the first time the boat had sailed for a week because of storms but that the weather looked good for our return trip. We had two nights at Francois and could enjoy ourselves. We had been watching the marine forecast every day for the past two weeks of our trip, trying to find a three-day window of weather when the ferry would be running; there were high winds and high seas every day and then finally the forecast looked good.

The south coast of Newfoundland has a series of fjords, which provide sheltered locations and harbors for fishing communities. The village of Grey River was the first village we came to, and was located partway up a fjord. We motored through pancake ice and past colorful houses to the dock, where about ten people were waiting for the boat. All these people helped unload bread and beer and Amazon boxes full of the stuff a small community needs. Snowmobiles and ATVs were the transportation in town.

We soon set sail again, with no new passengers – after all, who would go from Grey River to Francois in the middle of winter? The sea was rough and it started to snow, and was just about dark when we carefully navigated the narrow fjord that ends at Francois. By this time the wind was howling and the driven snow stung our exposed faces. We didn’t know where our rental place was, but the captain and another man showed us the way and took our bags for us on a snowmobile. We settled into our place for two nights, and ventured outside briefly to get a feeling for the town.

We spent the next day wandering the village along its boardwalks and pathways – remember, there are no roads needed in a town with no cars or trucks. All the houses are connected by these paths. The town is small, but has Sharon’s Place, a grocery and liquor store that is open morning, afternoon, and evening, with breaks for lunch and supper. There is a church that sits above the rest of town, and a large school that currently has six students and one-and-a-half teachers. This must be one of the smallest schools in the world in terms of the number of students! But education also arrives by computer, with courses available to older students online. There is a medical clinic, but no permanent doctor in town. There is a helipad used during emergencies.

Colorful houses are a feature of the town, with red and purple and turquoise tones mixed together in a delightful jumble. In winter some are occupied and some are not, with some people leaving for part of the year for jobs. There are stages along the waterfront: small buildings on stilts where fishermen stored gear and later processed the catch. These are a distinctive and wonderful feature of all the Newfoundland coastal towns.

We walked past one house just as a lady in perhaps her late 70s was leaving the house on this snowy morning to meet for morning coffee with two other ladies who were 84 and 85 years old. We spoke with her briefly, and she told us she had lived her entire life in Francois. There were 89 people living in this little town in 2016, and we met perhaps eight of them – all of whom had lived here nearly their entire lives, except for time spent in the military or going to school. This lady was really concerned about the dwindling population of Francois.

As the snow continued to fall, we met up again with Cody from yesterday’s boat ride when he drove up on his Ski-Doo (the Newfoundland name for all snow machines) and chatted with him about the town. After graduating from the town’s school, the St. Simon & St. Jude Academy, he went to work on his father’s fishing boat. Later, he bought his own boat and now fishes for crabs, lobster, scallops, and sea cucumbers with his wife and up to five crew members.

 Cody’s diverse fishing activity is a big change from the past, when the fishery was based upon the seemingly never-ending cod supplies. Alas, every time people think that a natural resource is unlimited, they use it up, and Newfoundland’s fishery was no exception. It was devastated by overfishing of the once common cod, a harvest made possible by technological advances utilized by both Canadian and foreign companies. In July 1992, with cod stocks down to less than 1% of historic levels, the Canadian government abruptly shut down the 500-year old cod fishery in order to try and save the fish. This instantly put 30,000 Newfoundlanders out of work and devastated local communities. In the years since some, like Cody, were able to diversify and found a path to the future. Others found a future in tourism, which is starting to take off in Newfoundland. The cod has since rebounded but the fishery is extremely small and limited compared to the good old days. Just try to get fresh cod in Newfoundland most of the year! 

A bit later we ran into another man on the boardwalk who was driving his Ski-Doo. He stopped to talk and told us that he was also a lifelong resident, but he didn’t make his living on the open ocean. He was a helicopter pilot who had worked for the Canadian Coast Guard, but now owns his own company and ferries a lot of people on remote hunting trips, mostly for Moose.

As I mentioned, the houses are scattered all around town seemingly randomly, with no clear lot boundaries. We asked one man about this, and he said that all the houses are built on Crown land, which is government land. People own their houses, but not the land under them.

We met another man driving his Ski-Doo who we had seen shoveling snow off a boat, which turned out to be his uncle’s boat. He works fishing for herring, crabs, lobster, and sea cucumbers. He was also a lifelong resident … are we beginning to see a pattern here? People are born here and live their whole lives here, though with a strong tether by ferry and by the internet and television to the larger world. When we asked Cody about his fellow citizens, he said that most everyone gets along well in town, but over time some people are moving away and the population is getting smaller.

The province of Newfoundland and Labrador has had a decades-long effort to move people away from the outports, which require huge government subsidies for ferry and helicopter transportation and education and medical care. By now, most Newfoundland outports have been abandoned, with the people voting to disband their towns and move elsewhere, but Grey River and Francois have been exceptions. In Francois, the question has come up for a vote twice over the years, but both times it was defeated (the latest in 2013) and the people remained. I understood that if the people voted to move out, the government would pay each homeowner $250,000 to compensate for the abandoned homes. It still could happen, but it is wonderful to see a few of the outports still hanging on against the tide of modernization.

I continued to photograph the buildings and waterfront and falling snow to my heart’s content on this wonderful day, when we talked to more strangers than we usually talk to in a week. Newfoundlanders are like that … they go out of their way to make visitors feel welcome, and we did.

There is even a good story that might be mostly true or wholly true about a German submarine that entered the fjord containing Francois during World War II. It came to quietly get fresh water for its tanks at a waterfall entering the sea. It was on a Saturday night and there was a dance at the community center in town; some handsome but unknown young men showed up who knew little English and who danced the night away with the local girls. The young women apparently thought that these might be Basque fishermen who often fished nearby, and didn’t realize that the men were German sailors.

The next morning we prepared to leave Francois for the voyage back, and the ferry Captain came to retrieve us. The morning showed a bit of sun and good weather for an ocean trip, so we went down to the dock and prepared to leave. The trip back was stunningly beautiful, with morning sun kissing the snow-covered headlands. And we got back in time to make the long drive to St. John’s to catch our flight.

MONARCHS IN WINTER

Monarch Butterflies Wintering at Pismo Beach

Sweeping through the sky, driven by cold fronts and the coming snows; heading southward and westward to the central California coast, where sunny days and mild breezes await. The journey is treacherous, with predators and sudden storms poised to take a toll, but many get through, ending up in a few coastal towns in a few parks and on a few trees, where they roost by the hundreds and sometimes thousands.

As a fifth grade student back in Michigan, now many decades ago, my teacher, Mrs. Triff, took us on a field trip to see migrating Monarchs at Point Pelee National Park in Ontario, Canada, which sticks down into Lake Erie like an arrowhead. There the migrating Monarchs are stopped in their flight path by the barrier of Lake Erie and concentrate there until the winds are favorable to continue the journey to Mexico’s mountains. The extraordinary experience of seeing so many beautiful creatures in one place never left me, so I jumped on the chance to see them again.

In January of 2020 we traveled to Santa Cruz and Pismo Beach to see the winter gathering of Monarchs. We had read about it for years, but there is nothing like seeing a magnificent gathering in person. These pictures are from the two balmy days we spent along the California Coast.

In Santa Cruz, we got directions to where the Monarchs were gathered, which happened to be next to a large surfing competition for young people (what could be more Californian than a sunny day filled with surfers catching the waves rolling in?). Meanwhile, the 2,500 or so Monarchs were tightly clustered on two individual trees: a Monterey Cypress and a Blue Gum Eucalyptus. In the clusters the Monarchs hung upside down, their wings tightly overlapped and the exposed wings were the undersides, so there were patterns but with the subdued colors more suitable for camouflage. When a Monarch flew into the roosting group, several butterflies had to resettle themselves to accommodate the newcomer, briefly flashing the vivid orange-and-black patterns on the tops of their wings. We found the experience extraordinary, but local old-timers (our age!) who walked or cycled by said that this was NOTHING compared to the butterfly gatherings of their youth, when apparently the California coast was a Woodstock for butterflies. But then Jimi Hendrix died and the world went to hell and all we have left is fond memories of our youth. But I digress …

The butterflies apparently come to the same trees each year, which is extraordinary, since NONE of the butterflies here this year were here last year. When they start their migration, the generation of butterflies heading south and west from all over the western states and western Canada are bigger, stronger, and brighter than the Monarchs of summer gardens. These SuperMonarchs are able to fly up to thousands of miles to those few trees guided by what: Genetic memory maps? Scents left on trees? Scientists don’t agree on the mechanism, although day length and perhaps the drive for food as the north gets colder in the fall are the triggers for starting the migration. For a fascinating discussion of the theories, go to Monarch Butterfly Migration.

After leaving lovely Santa Cruz and Monterey Bay, we drove south to another winter Monarch gathering of about the same size in Pismo Beach. Here the Monarchs were gathered on a few eucalyptus branches, with an endless stream of people migrating toward them on the path below, and pausing in a cluster to look up in wonder. Some of the Monarchs were getting in the mood for mating. An aggressive male would force a receptive female to the ground and laboriously try to pick her up. When he did, he would take her on a maiden flight into the treetops where, as the volunteer tour guide explained to the children, “they went for their honeymoon.” Extraordinary!

When spring approaches, the Monarchs begin their northward journey. The fact is, unless their summering grounds are near their wintering grounds, NONE of these individuals will make it. They procreate along the way, leaving eggs to hatch on milkweed plants. Then the hatched caterpillars voraciously feast on the milkweed, gaining nourishment and toxins (to repel predators), followed by the miracle of entering a chrysalis with golden stitches and eventually emerging as butterflies. Then the new butterflies head north, and repeat the whole process several hundred miles on, and so on for three or four summer generations. Then, come fall, the whole cycle repeats as a new SuperMonarch begins the migration south. And my sense of wonder is refreshed.
