NIGHTS OF THE SPRING PEEPERS

Spring is nature’s most joyous time to be a naturalist in northern latitudes as the world awakens from its long winter sleep. Near our Michigan home, Amish farmers are out in early March, when they begin to collect Sugar Maple sap from the awakening trees, and they use horse-drawn plows to prepare the earth for planting. Wave after wave of birds arrive from the southland, from Sandhill Cranes to Baltimore Orioles and hundreds more. The land awakens with spring wildflowers before the trees leaf out. The first insects appear, including Mourning Cloak butterflies that have overwintered under bark or leaves, and the Common Green Darner that has migrated up from the south. These are all great stories for a naturalist, but there is also a chorus that, to me, signifies that spring is here.

When night time air temperature rises into the range of about 35 to 40 degrees Fahrenheit, each little pool in the forest comes alive with the songs of Northern Spring Peepers. These tiny chorus frogs, each about the size of a thumbnail, peep together around the shores of a permanent or temporary pond–one that has no fish as predators. These are all male frogs trying fervently to attract mates. The calls begin shortly after sunset and end in the early morning hours, before the first traces of dawn light bring predators in the form of birds to the ponds.

Where I live in the middle of Michigan’s mitten, there are numerous little glacial kettle ponds, left as chunks of ice by the last ice age. When the ice melted, it left a depression filled with water, with high banks surrounding the new pond. These ponds are too small to support fish but are just right for Midland Painted Turtles, Common Eastern Toads, and Northern Spring Peepers. I set out on two nights to figure out how to see and photograph the peepers and I chose a pond that I could have easy access to. On the first night, the peepers were calling loudly when my nephew and I slip-slided down the steep hill leading down to the kettle lake. The frogs heard us coming and immediately became deathly quiet. We patiently waited without moving, and the peeps gradually slipped from stealth mode and awakened the heavens again with joyous noise. I spent a long time looking for the source of the calls, and finally found one little peeper calling from under the overhang of a fallen oak leaf right next to the pond. I was only able to get one photograph with a macro lens, a large bulky lens next to these tiny creatures. It was the opposite of stealth.

The setting: a small glacial kettle pond in the forest

Two nights later, I returned to the same pond, this time with my wife, Karen, and with the plan of using a snout wide-angle macro lens, which is about 18” long and only 5/8” in diameter at the lens end, which meant my face could be farther away from the peepers and I could approach them with stealth and cunning, or at least my version of stealth and cunning, which is usually clumsy and loud. 

We were quieter in approaching the pond than on my previous expedition, so the peeps barely interrupted their chorus of desire upon our approach, despite our use of bright flashlights. I showed Karen where I expected to see the frogs based upon my previous night’s work, but that proved to be fruitless, or frogless. In searching around a patch of shoreline where a peeper was loudly calling, we just couldn’t find it on the forest floor. But then I happened to see movement about 18” off the ground, and it was a Spring Peeper calling while clinging to the dry stalk of a wild perennial left over from last fall. Its little vocal sac was expanding with each call–so incredibly exciting to see in real life!

So I set up my snout lens on a tripod and approached to within about an inch of the calling frog. Meanwhile, Karen used a dive light–a powerful LED flashlight meant for deep dives in the ocean–to light the frog. Somehow, it didn’t mind the light too much and I was able to get hundreds of close-up photographs and videos of this frog and two of its nearby rivals in some of the most exciting hours I’ve ever spent (and, yes, I am truly a boring person). If you ever have the chance to experience the sounds of Spring Peepers while standing among them, don’t miss the opportunity!

MORE DETAILS ABOUT THE LIVES OF SPRING PEEPERS 

The Spring Peepers calling in a chorus around a pond are all males, trying desperately to attract mates. Presumably the biggest and loudest male wins the wooing contest, allowing them to mate with the quiet and choosy females. After mating, the female lays eggs in the little pond. Tadpoles are the hoped-for result, and the cycle of life continues.

Spring Peepers are the color of leaf litter on the forest floor: tan or brown or green. Hence they can remain disguised. The second word of their scientific name, Pseudacris crucifer, refers to the large dark cross on the back of each frog. I believe this is part of the camouflage, which breaks up the otherwise uniform color and looks like the veins of a leaf.

A Spring Peeper looks a bit like a dried leaf on the forest floor; the cross marking on the back and other markings on the legs break up the color, making it look more like fallen leaves

These are tiny creatures. In fact, were you so inclined, you could mail seven of them in a one ounce first-class mail envelope, though the USPS and peeps wouldn’t be very happy.

Spring Peepers are tiny in comparison with the loudness of their group

Peepers go into suspended animation all winter, spending the long, cold months hiding behind a flap of bark on a tree or under a fallen log or under the leaf litter on the ground. Their bodies can survive freezing down to about a 17 degree Fahrenheit body temperature because of glucose and other chemicals in the blood that act as antifreeze.

To get these pictures, I used a long Laowa Macro Probe lens with a strong dive light

To make their calls, the males take air into their lungs, then close off their nostrils and mouths. As air is forced from the lungs by muscles, it passes over vocal cords and into the inflated air sac, creating the sound variously described as peeping, chirping, or sleigh bells. The sound is loud enough to prevent sleeping for some people, and is a shimmering shower of sound when it surrounds us next to a pond.

The slightly bulbous toe pads are designed to stick to wet or dry vegetation to facilitate climbing
Just to the right of this calling Peeper is the warty leg of a much larger Eastern American Toad

A typical male peeper can make up to 13,500 calls per night, though I didn’t do the math and am depending upon scientists for this factoid.

And the most astounding fact of all: a group of Spring Peepers around a pond is referred to an an “army.” A noisy and tiny army, but an army nonetheless.

A DAY AMONG THE AMISH

Loading freshly cut blocks of ice onto a horse-drawn sleigh at an Amish farm

Today was a gift from the universe.

I had an instinct that today (4 February 2023) could be the day when Amish farmers cut ice from their ponds to fill their icehouses after the cold snap of the last week, a warming weather trend ahead, and tomorrow the sabbath. We drove out into the Amish community this morning, and almost immediately saw a freight wagon loaded with ice. We drove on, and found another farm where wagons were lined up in front of a pond, where men wearing straw hats were cutting ice.

We parked at a respectful distance, watching and discretely photographing for about an hour. Then an Amish man came walking up to where we were parked along the road. He was a young man and kindly asked if we had ever seen Amish ice cutting before. We said “only at a distance,” and he invited us to come down closer to see it. I asked if it was okay if I took pictures, and he said “Yes. Just not too close.”

So we went down near to where ten men and teen boys worked as a team to cut the ice with a gas-powered circular saw and load six sleighs and wagons, each drawn by two draft horses. Assorted young boys all wearing matching dark knit hats and a dog completed the perfect rural scene.

We got to talking with the young man and his little brother, and he invited us to have a meal with them. So we sat down for a noontime dinner with the father, mother, 11 of their 13 children, and a couple of young men from a nearby farm. After a hearty meal, they went back to ice cutting and me to my pictures. Magic happens.

As I said, a gift from the universe to two shy people.

Notes from our conversations with an Amish family:

Since most English (the word used by the Amish for non-Amish people like us) know little about the Amish, I will tell you about our discussions with this kind and generous family.  My wife Karen and I talked to the farmer and his wife, as well as with some of their sons, both before and during the meal, learning a bit about their lives. They have 13 children, of whom 11 still live at home. The other two are the older adult children, both married, with the son living on a small farm in an Amish community in Illinois and the daughter at a farm nearby. The children were spaced quite regularly in age, with the youngest son being two. Of their children, nine were boys and four girls. The eldest daughter still living at home now teaches at an Amish one-room schoolhouse eight miles from their house.

The Amish have not been here for as long as they’ve been in Pennsylvania. My parents moved to the area in 1980, when they built the house that we now own. A couple of years after they moved in, one of their friends said that Amish were starting to buy up the surrounding farms, and that the land was about to blossom with new activity and a flourishing of crops. The farmer in my story moved here when he was a boy, in that first wave of Amish. He said that the price of the land was good. The families here have done well, with what appear to be prosperous and beautiful farms.

The family has an extensive summer garden, where last year they planted and harvested over five acres of pumpkins and winter squash. Some of their crops are sold at a local open-air produce auction, which we’ve driven past at times when it wasn’t open. It is like a farmer’s market, open only prescribed days each month. At this time of year firewood and hay are for sale, but in summer and fall there would be a wonderful variety of produce and flowers. I remember last year seeing a horse-drawn farm wagon with clear plastic sheeting forming a greenhouse structure over the wagon. Inside there were colorful hanging baskets of flowers protected from wind by the plastic.  I think the flowers were headed to the farm auction. Here is an article about this particular auction facility: Stanwood Produce Auction

The young man who initially invited us down to see the ice cutting is 18 years old, friendly, and personable. He talked about the economics of the farm. They have a sawmill, as many of the local Amish farmers do, where loggers bring loads of softwood logs. The farmer brings the logs one by one into the mill, where they are sawn into 2×4’s and other dimensional lumber that is sold to a pallet maker south of Grand Rapids; that factory is perhaps 80 miles away, so the wood has to be transported by truck to the buyer. I’m sure the sawmill is a major source of income for the family. I mentioned that there has been a great increase in the number of Amish farms in our area with sawmills and wondered about the competition. The father said that so far it wasn’t a problem, that there was enough demand and that some of the sawmills were for softwood and others for hardwood. I think they also have a maple sugaring operation, as do many of the local families.

The farmer would also grow corn and hay for feeding the livestock. In early spring he would use a horse-drawn plow (on local farms we’ve seen up to six draft horses pulling a plow!). Horses would also be used in the harvest of hay, with freight wagons piled incredibly high with freshly dried hay.

The farm has ten cows for milking, which has to be done twice each day. In fact, the purpose of this family’s ice harvesting is to build a store of ice that can be used the rest of the year to keep the milk cold. The milk is sold to nearby people who come by once a week to pick up a gallon as part of a farm share program.

We asked the son if Amish had to get jobs to make ends meet. He said that in the last few years the economics of farming alone don’t work, so it is common to have to get a job outside the community. In the local Amish community, all the farms have a small business of some sort: making rustic furniture, creating poly-wood furniture, repairing clocks, caning chairs, butchering cows, making rugs, selling eggs, making boat covers, and probably a dozen more crafts that bring in money.

The day looked like fun for all involved, especially the young boys looking on

On our visit there were two families working together to cut ice to fill two icehouses. The patriarch of the host farm operated the gasoline-powered circular saw used to cut the ice. This year the ice was only about six inches thick; more commonly it has been eight or up to twelve inches thick, so it would be harder to heft those blocks. The ice cutting machine is homemade, with a long lever used to raise and lower the spinning blade. He cut the pond ice almost all the way through, stopping about 1/2” short of cutting through. Then another man used a long steel pole to break off the blocks. A heavy rope stretched across the pond was used by two workers to move the floating blocks of ice to where the loading conveyor belt was located at one end of the pond. Then the men used pitchforks to prod the blocks onto the conveyer, which is also their hay lifter, powered by a gasoline motor. The Amish use some modern assistance when they deem it appropriate.

The family that owns the ice pond uses horse-drawn sleighs to transport blocks of ice to their icehouse, while young men from the farm down the road used horse-drawn freight wagons. We counted a total of six sleighs and wagons, each pulled by a team of two massive draft horses. They took turns at the conveyor machine that was lifting ice from the pond. Once one vehicle was filled with a layer of ice, the driver would quickly move it away. Another was already lined up to move into position, with the driver sometimes using the team of horses to back up the wagon to the loading chute. Managing horses to back up this way is an incredible skill and they do far better than I do trying to back up a trailer with a car! Most of the sleighs and wagons were drawn by two Belgian horses, the predominant breed in our area, which are usually chestnut-colored with blond manes. A few of the wagons were drawn by black Percheron horses. We were told that the white horse in one team was actually a Percheron, born black and then it had turned pure white.

The massive Belgian horses make great teams for hauling ice and plowing land

One young boy named Neil enjoyed talking to us and telling us about his life on the farm. He asked if we had a farm, and we had to answer no, but that it looked like a lot of fun to live on a farm. He was in the fourth grade at school; I asked him what his favorite subject was and after thinking for a moment, he said “reading.” He said they were reading a book by Laura Ingalls Wilder called “Little House in the Big Woods.” He said that sometimes the teacher reads and that the children also take turns reading. He said that another grade level reads “Farmer Boy,” another Wilder book that I told him I had read as a boy. It has been many years since I read it, but I remembered that I first learned about tapping maple trees from that book. I needed a refresher about the story, so here is what Wikipedia says about Farmer Boy: 

“The novel is based on the childhood of Wilder’s husband, Almanzo Wilder, who grew up in the 1860s near the town of Malone, New York. It covers roughly one year of his life, beginning just before his ninth birthday and describes a full year of farming. It describes in detail the endless chores involved in running the Wilder family farm, all without powered vehicles or electricity. Young as he is, Almanzo rises before 5 am every day to milk cows and feed stock. In the growing season, he plants and tends crops; in winter, he hauls logs, helps fill the ice house, trains a team of young oxen, and sometimes — when his father can spare him — goes to school.” 

This sounds exactly like the life of young Neil: no wonder he loves the Laura Ingalls Wilder books!

I asked Neil if he milks the ten cows, and he said he was still too little for that, but that he feeds their five calves and many chickens each day. He also collects the eggs daily from two chicken coups. I asked him how many eggs: he was unsure of the numbers, but maybe 30-50 from each coup (he said the total was never 100). He pointed out the pony they had gotten and was very fond of it. We asked if they name their animals and he said “no” and he laughed; that seemed like a strange idea to him. He was really glad that this year ice cutting was on a Saturday when he wouldn’t be at school, so he could watch and be part of it. He recalled when they had a backhoe come in to dig the large bowl-shaped pond for the ice.  Later we saw him riding on an ice sleigh, and it looked like it would be a day of heaven for a ten year old! Neil has an infectious smile and enjoyed telling us about his life.

My dear readers, you must be wondering what it’s like to be inside an Amish house; I know we have been curious for years. We finally got our chance when we were invited in for noon dinner. We drove into their driveway and were shy about knocking on the door, in case the Amish wife hadn’t been told of our arrival. After a moment, she appeared at the door with a small son and I walked up to say hello. She said “Will you be joining us for dinner?” So of course I said “yes.”

We went inside, and she escorted us from the entry room, through the dining room/kitchen, to the living room. The living room had a wood-burning stove and the dining table/kitchen area was warmed by the cook stove. The openings between the rooms were large, giving the feel of one big room and also helping to provide even heat to the first floor. We believe that the large room is also used for community church services, but on some farms they use the barn instead of the house. The Amish don’t have a church to go to; instead, they take turns holding services for the nearby community. Every two weeks the community holds Sunday services; each farm hosts for two Sundays, then they rotate to another farm. This family was going to host church services at their home the next day. We have seen Sundays when a farmyard is filled with buggies, perhaps 20 to 30 at a time. Recently we saw children walking home from church, the girls in their black woolen coats, white aprons, and black bonnets, and the boys dressed formally as well.

The Amish house where we had our noontime dinner is in the distance

There is no electricity in an Amish home, so natural light during the day and oil or gas lamps at night are the sources of illumination. No televisions or computers, of course. And no plush furniture. Around the perimeter of the living room were wooden rocking chairs, which is where Karen and I sat while waiting for the meal. The youngest boys sat lined up on rocking chairs along one wall, reading long hand-written letters. I didn’t ask who the letters were from, but I could imagine that they could be from the family of their brother who had moved to Illinois and other distant relatives. And, unlike most English children today, they had no problem reading the letters written neatly in cursive!

The house was a comfortable temperature. The lady of the house said she is fortunate that her husband has a sawmill, because there is always plenty of wood to keep their home warm. They cooked on a huge old cast iron wood-burning stove, which also helped heat the house. 

There were no family portraits or pictures on the walls, since the Amish don’t wish to have recognizable pictures of themselves, instead believing that humility is to be honored, and individuality and pride are harmful to the community. They follow the Biblical commandment “Though shalt not make unto thyself a graven image.” I took pictures after getting permission from one man and nobody seemed to object, but I was careful to photograph the activity and not the individual. No portraits.

After a few minutes, the Amish wife told us it was time for the meal and indicated two places where we could sit. As you might imagine from the size of the family, the long rectangular table was huge; I think there were 13 of us sitting around it, with the father at the head of the table. Three daughters remained in the kitchen and served the food. When everyone was seated, the Amish father bowed his head; everyone took his cue and bowed their heads as well and all thought a silent prayer for about a minute. Following that, bowls of food were passed.

Dinner was hearty; after all, the men working outside had been cutting and hauling ice, hitching and unhitching teams of huge horses, and lifting heavy blocks of ice into and out of wagons. They were hungry! There were two sets of bowls serving each of the foods because the table was so large. The young men took huge helpings of mashed potatoes and gravy. The meat entree was excellent meatballs and sauce (Karen had to poke me for initially trying to take three meatballs when she noticed that everyone else took two!). There was a bowl of mixed vegetables, a smaller bowl of cabbage salad, and a plate of sliced cheese. After everyone had their fill, two desserts were passed: a chocolate pudding pie and an apple dish that might have been apple crisp. The oldest daughter was the baker.

The young Amish men were curious about our Washington license plates, and we told them we live there most of the year. They asked about Washington state and had heard that part of the state got considerable rain. They wondered why rain and not snow, since it was about the same latitude as Michigan and they seemed to understand when we explained how the influence of the warmer ocean moderates the temperature.

The family enjoyed hearing our story from several years ago of driving an icy road and coming upon a wagon loaded with ice blocks off the road in a ditch. I stopped and asked if I could help. The young man asked me how many horse power I had under the hood of my Subaru and we all laughed. They had another team of horses on the way to help.

They wanted to know where we lived locally and what we did during the day, though what we do is less interesting than what they do! We were at a bit of a loss as to what to say we do, as it didn’t seem appropriate to tell them how much time we spend with our computers or watching television. We asked a lot of questions about their lives and they were pleased to answer. Nice people. I noticed that the school-age children said virtually nothing during the meal (perhaps something about being seen and not heard!). They also all noisily completely cleaned their plates with the sharp sound of silverware striking china. No food was wasted.

After dinner, all bowed their heads again to thank God for the meal. Then everyone disappeared to complete their ice cutting tasks, with the women and girls staying inside to clean up after the meal. In Amish life the roles of men and women are well defined and traditional.

The men had to gather up the horses, who had also been given a break from the harness to feed on hay in the barn, so they all had to be reattached to their sleighs and wagons. We said our thank-yous and goodbyes, pulled on our boots, and went back to our car. I took a few more pictures–actually, the best of the day–and we took our leave. It was an extraordinary experience for us, and it felt like the family enjoyed talking with us, letting us into each other’s lives for a few hours. I bow my head in grace for the time we spent among the Amish.

A day’s work well done, with all enjoying the experience

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.

Southern Flying Squirrel showing biofluorescence under UV light on the left, with the same species illuminated by tungsten light on the right. The belly fur changes from off-white to bubblegum pink when struck by UV light.

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.

The photographs above are a good representation of the Southern Flying Squirrel in UV vs visible light. The final photograph shows the deck setting at night where all the pictures were taken, and includes one flying squirrel for scale. Click on the photographs to see them larger.

THE AMISH IN WINTER

The Amish live close to the land, necessarily incorporating seasonal rhythms into their lives. After all the plowing and planting and nurturing and harvesting, the landscape breathes a sigh of relief as the world enters winter dormancy.

But not the Amish. Their lives are still busy with the daily rhythms of farm life. The horses and chickens must be fed. The children must walk to their one-room schools. Ice must be harvested. Laundry must be washed and then dried out on the line. The sawmills continue operating. Wood must be cut for warmth. Barns are built. Quilts are sewn. Sunday worship is not to be missed, as the believers gather in one home, converging from nearby homes by foot and by buggy.

It is a life apart, and that’s what those of us viewing from the outside find enchanting and ultimately unknowable, because we can only view the surface.

The photographs here represent six winters of quietly and respectfully observing these families at an undisclosed location in central Michigan.

MICHIGAN AMISH: A Timeless Way of Life

Stopping by a farm on a snowy morning

Imagine rural America as it was in the late autumn of 1875. Horse-drawn buggies pass by, the drivers greeting passers-by with a wave. Children play in the snow outside a one-room schoolhouse. Farmers are out on the pond, cutting ice to put away for the distant summer. Eggs and quilts are for sale at a roadside farm. Men pitch in to build a new house for one that burned down …

Except it is not 1875: it is 2010, in a pastoral landscape in central Michigan where scores of Amish farms and families have established a community during the past 25 years. This is the area where my mother lives, though she is not Amish. I remember when the first families arrived and bought some old and tired farms; my mother was talking to a man who had experienced the Amish arriving in other areas, and he said something to the effect of “You are going to experience a wonderful renaissance here, as the Amish bring the worn-out soil back to life.” He was right, and I’ve watched through the years as the numbers of Amish rose and the landscape came back to life.

My photographs here were all taken on several brief late autumn and early winter drives through the Amish landscape, so they comprise just a snapshot of a different way of life. I wish I could spend time getting to know these people, but I live half a continent away and it isn’t easy to strike up a conversation between buggy and Buick.

While there, I watched three different Amish wagons, drawn by draft horses, coming across the fields from unseen ponds, each carrying a shiny load of freshly cut ice. The blocks of ice were perhaps 8″ thick, reflecting a long and cold December, and they had the slight blue-green tint hinting at their pond origin. I watched one pair of men putting the blocks into an insulated shed using big, steel ice tongs.

This brings me back to a childhood memory of my family buying ice during a circa 1960 camping trip in the Upper Peninsula. Along the waterfront in Copper Harbor, on the Keweenaw Peninsula which juts jauntily into Lake Superior, there was an old-timer selling his ice from an insulated shed. He hauled it out with tongs, and rinsed off the insulating layer of sawdust by dunking the block in a galvanized tub of lake water. My dad then put the block in our green Coleman ice chest to take back to the campground at Fort Wilkins State Park. That kind of experience has pretty much vanished in 21st century America.

When I toured the Amish landscape on a Monday, nearly every farmer’s wife had set out her wash to dry in the sub-freezing winds. Some had lines strung up on the farmhouse porch; others had lines in the yard, where blue denim overalls shared the breeze with colorful quilts.

Signs in front of the old white farmhouses proclaim what is for sale, usually with the disclaimer “No Sunday Sales.” Some will be selling brown eggs and honey; others might have quilts or deer blinds or maple syrup or freshly-baked pies. The families make plenty of time for these enterprises; after all, there aren’t umpteen hours of television per day, or 300 tweets per day, or email, or shopping for the latest fashions. These people live off the electric grid. In fact, should catastrophe hit America, we will be looking to the Amish to see what we can emulate from their self-sufficient way of life.

While driving one gravel road, I came upon a big wagon with two draft horses parked in one lane of the narrow road. Two Amish men were cutting firewood from roadside trees and loading it on the wagon. Their dog sat looking at me

from the other lane, blocking it, so I waited patiently for one of the men to see why I was parked there. He realized that the dog was in the way and called it. He laughed; I laughed; and we had a moment of human connection.

I saw three one-room schoolhouses in the area. Through the windows of one, I could see children praying. Later, I saw about ten children, clad entirely in black, playing in the white snow during recess outside another schoolhouse. Amish children clearly enjoy their snowball fights!

Had it been late spring, I would have seen the Amish children walking to school in their traditional clothes, complete with straw hats. Amish men also wear straw hats, and Amish women wear long dresses, even while working in their beautiful gardens. The ladies wear hair coverings in the summer and black bonnets in the winter. Many Amish go barefoot in warm weather.

On this trip I saw the spread of sawmills among the Amish–at least a half-dozen farms had associated sawmills. This is a good fit for the Amish, because many of the farms have woodlots where the farmers can take a sustainable harvest of hardwood oaks and maples. One woodlot was set up as a sugarbush, where each March the farmer would tap the Sugar Maples, collect the sap, and boil off the excess water to make one of the most flavorful products on earth–maple syrup.

As I sit here at my computer typing this story, I realize one of the aspects of Amish life that I envy: the Amish men spend their lives outdoors doing hard physical work. They plow fields, stack corn, milk cows, split firewood, and accomplish all the other necessary chores around a farm. These men stay in great shape from their work, while I have to jog mindlessly along a road or work out on a fitness machine as a necessary counterpoint to my digital life. I wouldn’t trade my life for theirs … or would I? Probably not.

The Amish life would work for many, but for me the rules of the religion would be something of a straightjacket. Creative expression does not often blend well with fundamentalism.  So here I am, living an imperfect life, but one that allows me as much flexibility and creativity as I can muster. And there they are, living satisfying lives in the shelter of a like-minded community. We are essentially different, and I love this diversity of lives that America encourages.

Horses are a daily part of Amish life; they plow the fields and pull the buggies and assist in much of the other work around these farms that harken back to an earlier time
