CHANNEL ISLANDS NATIONAL PARK: Exploring Santa Cruz Island

May 31, 2012

Island Foxes greet each other with obvious affection; seeing these foxes was the highlight of our journey to Santa Cruz Island

En route to Santa Cruz Island, the boat’s captain steered us off course, so we could see dolphins porpoising (or is it porpoises dolphining?) over the Santa Barbara Channel. Our crossing was smooth, so we were glad that we hadn’t applied the seasickness patches; they work, but make me groggy.

We pulled up to Scorpion Anchorage, a protected cove with a dock, where a National Park Service Ranger greeted us and filled us in on the rules and regs. He also checked our campground reservations.

Visitors arriving on the Island Packers boat from Ventura; from here we carried our packs and other gear about a half a mile to the campground.

Then we gathered our gear and began the scant half-mile trudge to our campsite, which proved to be a lovely spot under huge old eucalyptus trees that were planted in the early days of Scorpion Ranch. There was a picnic table and a pair of food lockers, one at each end of the table, to ensure that campers’ food was kept away from the inquisitive and daring little Island Foxes that trot through the campground with regularity, as well as the startlingly intelligent Common Ravens that know we are a source of food.

After setting up our tent, we followed a trail up Scorpion Creek, then went off trail into Scorpion Canyon, in hopes of seeing the Island Scrub-Jay among the oaks that thrive in that canyon. Skirting pools of standing water, we walked and scrambled up the rocky, narrow reaches of the canyon. It was lovely, with red rocks and intricately branched oaks. There were lizards and small birds and species of plants that we had never seen before. There were even a couple of small rock overhangs, one of which had clear evidence of early humans. With the pile of chert and abalone shells out front, we could imagine a Chumash Indian crouching there, eating a meal and waiting for night to steal away the day, revealing a stunning spread of the Milky Way overhead.

Then we heard it … a clear call of a jay. In the oaks across the canyon, higher on the dry slope, there was a big, blue Island Scrub-Jay foraging in the branches of an oak. This species lives nowhere else on earth, so all the bird listers from across North America have to make a similar pilgrimmage into this remote canyon in order to add the species to their life list.

Island Scrub-Jay–a species found nowhere else on earth. This species is substantially larger than its nearest relatives on the mainland, and makes its living feeding mainly on Island Live Oak acorns.

After the jay moved on, so did we. The day was getting late, so we had to figure out how to get out of the canyon and back to camp before nightfall. We decided that instead of going back, we would try to climb out of the canyon by going due north up the steep side of the canyon. It was a huff-and-puff climb and scramble, but eventually we emerged onto a stunning, grassy plateau, where we followed an old ranch road toward Potato Harbor. As we gazed down toward the crashing sea below, Karen spotted an Island Fox trotting through the grassland. This was incredibly exciting for us, since we had hoped to see a fox but thought the chances were remote. Little did we know that, since their population recovered from near extinction, the little foxes are again thriving and don’t seem to mind being seen by humans. They are certainly not tame, but they are not especially afraid of us, either.

Island Foxes are about a quarter the size of their closest mainland relatives, and saw their populations plunge from above 2,000 in the 1990s to below 100 about seven years later, due to a complex series of events set in motion by mankind. I will fully explain this chain of events in a coming weblog.

We watched a second fox hunting in this area above Potato Harbor, and this one had on a radio collar that was recording its every move, so that scientist could monitor the recovering fox population.

Is it just me, or does this formation above Potato Harbor look like a warning that Indiana Jones would have disregarded?

With darkness coming fast, we switched on our headlamps and followed the old Potato Harbor Road back toward the campground. As the road led steeply down off the plateau, we crossed some extensive patches of bare, white earth. These were different from most of the soils of the island, and they turned out to be diatomaceous earth, which is composed of billions of silicon skeletons of algae that once lived in the sea.

We reached the campground well after dark. While walking through the campground, Karen caught the gleam in a fox’s eye as it stood atop a picnic table, foraging on food left on the table by some campers who had turned their backs and were rummaging in their tent. Another coup for the wily fox!

That night, the stars splayed magnificently across the sky as we prepared a backpacking dinner with the hiss of the MSR stove and the stabbing rays of our headlamps. Deeply tired, we sank into pleasant sleep.

The next morning, we awoke to beautiful sunshine on the grassy hills rising across Scorpion Creek from our campsite. We spent a couple of pleasant hours exploring the Scorpion Ranch buildings and immersing our minds in the lives of those who spent generations here, growing grapes, raising hay, tending sheep, maintaining roads, and all the other tasks of a large-scale rancher. The National Park Service has maintained the ranch buildings beautifully, and repurposed one of them for use as a visitor center. This is the area where people coming off the boat for the day generally have lunch, and there are plenty of big lockers to keep food from the foxes while people are taking a short hike or exploring the ranch buildings.

We stopped and photographed an Island Fox in the bright sunshine as it foraged among the tall grasses of the hillside. Then we walked down to the pier to see what tide pool creatures we could see, and were rewarded with the sight of a colony of bright purple sea urchins. There was also a crab that was bigger than we expected to see–about a foot across. We got glimpses of it through the kelp that waved back and forth. There were fish about a foot long, and we looked for large, bright orange Garibaldi (California’s state marine fish), but didn’t see any.

We decided to do another hike up Scopion Canyon, to see if we could get a closer look (and photograph) of an Island Scrub Jay. We enjoyed good looks at Pacific Chorus Frogs and their tadpoles. We also saw a new bird species for our life list–the Rufous-Crowned Sparrow. We eventually saw a jay, but it kept its distance.

Again, we climbed out of the canyon onto the plateau. This time, as we looked down the length of Santa Cruz Island where the steel gray Pacific met the land, there were thick gray layers of clouds, with watercolor washes of rain falling on the distant hills. We decided to head quickly back to camp.

That night, the heavens opened up, with hard rain all night. We stayed dry in a new tent, but other campers weren’t so lucky. Two young men were sitting glumly at their picnic table early the next morning; when I asked them if they got wet, they grumbled that they were soaked, because water came up through the bottom of their tent. Later, I watched them pouring GALLONS of water from the tent as they packed up. I asked a lady ranger how much rain had fallen overnight, and she said there was about 1.6.” That’s roughly 10% of the yearly annual rainfall here. There were puddles in the road, but the plants looked as fresh and happy as the wet campers looked wet and dejected.

In the unsettled weather, we decided to hike the dirt road to Smugglers Cove, where there was another old ranch. The road surface was slick from the overnight rain, and our hiking boot treads caked uncomfortably with heavy, squishy mud. Once atop the plateau, the views across the open grasslands toward the sea and the distant mainland were stupendous. We stopped for a break in a grove of Monterey Cypress, then continued on to the ranch. Descending the steep hill to the ranch, we walked past an old grove of olive trees, planted when the owners long ago decided to get into the olive business.

As we approached the ranch from the cobble beach, four foxes that had been foraging in the meadow scattered into the adjacent brush. The ranch still had plantings of bougainvillea, which was bright with magenta blooms. We took shelter under the eaves of a building next to the ranch house during a hard shower; and I took the opportunity to pick a couple of oranges for us from a tree. As northern people, we had never before had the opportunity to pick oranges fresh from a tree [In contrast: when I was displaying my photography at an art show in San Francisco several years ago, one woman said my photograph of apples hanging on a tree in late autumn, and she said she had never seen an apple tree!]. There was also a nearby lemon tree, very pretty, but we decided that these fruits were impossible to eat fresh from the tree.

After leaving the ranch and heading back up on the plateau, we took a spur road that led up to an abandoned oil well, where I stopped to photograph the

old machinery. Then we descended steeply into the valley of Scorpion Creek. In the valley, Karen suddenly stopped and said that a Loggerhead Shrike had just dived into a bush about four feet away from her. I got out my long lens and was able to get great photographs of the shrike when it emerged and perched atop the same bush, perhaps eight feet from us. It lingered a long time, enabling me to get dozens of photographs at this unexpectedly close range. This gave me a sense of part of what the National Park Service means when they call the Channel Islands the “Galapagos of North America.” The wildlife is abundant, different from the mainland, and not very afraid of people.

We walked back along the trail along Scorpion Creek, which had turned from a dry creek bed with intermittent pools where frogs lived lazily with their tadpole offspring, to a raging, brown current that moved boulders, carved stone, and carried little tadpoles out to the playground of sharks. This was an excellent lesson in canyon-cutting, and we were glad we didn’t need to hike up narrow Scorpion Canyon again in order to see endemic jays. We might not have made it.

On our next and final morning, we hiked up a trail to Cavern Point. Nearing the top, we saw a fox trotting up the trail ahead of us. Suddenly, it dashed across the meadow; I thought we had scared it, but then we saw what it was doing. It had sighted another fox across the field and was running over to see it. It was like a glorious reunion of people who have not seen each other for years. Well, maybe a bit different since there was tail-wagging (I didn’t realize that foxes could exhibit this dog-like behavior) and vigorous sniffing that looked like kissing. After a long greeting, the two foxes foraged in close proximity to each other. It was thrilling for us to be able to see such fascinating emotional behavior.

Then it was time to leave. We were extremely satisfied with our hikes and wildlife sightings. What a wonderful place!

To get to the Channel Islands, Island Packers offers boat access to each of the islands.  Check their web site for all details and schedules. The National Park Service has excellent descriptions of Channel Islands National Park, including information about the biology and geology of the islands, and the rules for visiting. T.C. Boyle has a new novel, “When the Killing’s Done,” about the ethical implications of the National Park Service’s replacement of exotic species in the Channel Islands with native species; it’s an excellent and timely novel for anyone interested in National Park policy.
