To Sheldon’s surprise, the truly irreplaceable link in Alaska’s food chain was the willow ptarmigan (Lagopus lagopus). These birds mated in May and their eggs hatched in June. They were particularly thick in Roosevelt’s Yukon Delta.20 Once their white downy feathers were lost, the ptarmigan’s plumage turned as brown as the willow, dark birch, and spruce boughs. They were well camouflaged, clinging to the ground to feast on wild berries and willow buds. When flushed, the ptarmigan, which are plump, seem to struggle with flight, forced to keep a low trajectory only ten to fifteen feet above the ground. The naturalist Margaret E. Murie, in Two in the Far North, joked that the ptarmigan was a comical creature, seemingly saying, “Come here, come here, come here—go back, go back, go back.”21 Every predator in Alaska considered the willow ptarmigan fine dining. The red foxes and ground squirrels, in fact, seemingly identified the brown-speckled ptarmigan eggs as the finest delicacy on the tundra. Other birds—golden eagles (Aquila chrysaetos), gyrfalcons, short-eared owls, and goshawks among them—swooped down to lift away willow ptarmigan in their claws for dinner.22 For wolves and wolverines, the willow ptarmigan was a veritable Thanksgiving dinner in waiting. Once ptarmigan were devoured, the tree sparrows (Spizella arborea) and white-crowned sparrows (Zonotrichia leucophrys) collected the feathers to use as nest lining.23 “The ptarmigan,” Sheldon reported in his field journal, “flying from rock to rock above, kept sounding their croaking chatter.”24
The primordial bird populations in Alaska included 100 million seabirds, 70 million shorebirds, and 12 million waterfowl. (Unfortunately, there were even more mosquitoes that swarmed up out of the marshlands.) Charles Sheldon—considered by both Grinnell of the Boone and Crockett Club and Merriam of the Biological Survey as the best young American naturalist-hunter—ended up inventorying the birdlife around the north base of snowcapped Mount McKinley with scientific exactitude. He published his findings in the January 1909 edition of the Auk. More than 400 bird species inhabited or migrated through Alaska, including many Asian species. Sandhill cranes and golden eagles were found throughout the territory, feeding along mirror-still lakes. The Aleutian chain was full of colonies of raucous seabirds, which Sheldon never got to inventory.25
One bird that Sheldon admired during his Alaskan wanderings was the trumpeter swan (Cygnus buccinator). With its bright white plumage, long periscope-like neck, and black bill, the trumpeter swan—the largest waterfowl species on earth—was magnificent. Besides being the unfortunate victims of fashion—women wanted their feathers for bonnets—these swans were sensitive to contaminants. A small colony of trumpeters lived in the lower Copper River system and the Kenai Peninsula. They bred in northwestern British Columbia and in the Saint Elias Range backcountry; those populations, however, were not faring well.26 Determined to help the trumpeter swans survive in their core range in Alaska, Sheldon worked with the Boone and Crockett Club, the New York Conservation Society, and the Camp Fire Club of America to help protect the swans. In 1968 the nonprofit Trumpeter Swan Society assumed the full-time duty of advocating the protection of these regal birds. E. B. White’s The Trumpet of the Swan, published in 1970, memorably introduced these beautiful birds (which can stand on one leg for more than half an hour) to many children.27
Market hunters were the bane of Sheldon’s days in Alaska. One afternoon while Sheldon and Karstens were tracking Dall sheep, they came upon a couple of hunters with sixteen dogs around a campfire. They were gorging themselves. They had slaughtered a herd of Dall sheep, including the ewes and lambs—the whole family—which Sheldon had been inventorying. “Naturally,” he wrote, “I was deeply disappointed to hear that my sheep, which I had been so carefully observing, were to be disturbed by vigorous market hunting, but could do nothing to prevent it.”28 He vowed to fight for laws to protect Alaskan game against “slob hunters” who didn’t even know what conservation meant. And he mistakenly warned Natives not to trust Hudson Stuck, a Presbyterian minister whose Ten Thousand Miles with a Dog Sled, filled with tales of cold winter journeys on behalf of Christ, became a best seller.29 Before long, however, Stuck became Sheldon’s ally. In 1913, Stuck led an expedition up the summit of McKinley. His memoir of the climb was titled The Ascent of Denali.30 With almost evangelical vigor, Stuck insisted that the name of Mount McKinley was an affront to the mountain and Native people and should be changed back to Denali. “There is, to the author’s mind,” Stuck wrote, “a certain ruthless arrogance that grows more offensive to him as years pass by, in the temper that comes to a ‘new’ land and contemptuously ignores the Native names of conspicuous natural objects.”31

The 1907–1908 year on the upper Toklat River (in an area that became part of Mount McKinley National Park) was brilliantly described in Sheldon’s memoir The Wilderness of Denali. Nowhere in the world, Sheldon proclaimed, were there mountains as majestic in winter as the Alaska Range. He felt privileged to have walked among such towering manifestations of the ice age. The Alaska Range, filled with swollen rivers in springtime, divided the Alaska territory not only into districts but also into distinctive climates. For an experienced mountaineer like Sheldon, tramping around the crags, clefts, waterfalls, and marshlands of interior Alaska was far better than climbing the comparatively dull Matterhorn in Switzerland. Besides the Alaska Range, there was the Rocky Mountains extension that slashed across northern Alaska as the Endicott Range (about 200 miles from the Arctic Ocean). The Coast Range, which John Muir also loved, consisted of the Fairweather and Saint Elias mountains, with peaks over 10,000 feet high (here were the blankets of glacial fields). The Wrangell Mountains were a string of unsymmetrical lava cones with peaks—Blackburn, Castle, Drum, Jarvis, Regal, Sanford, Wrangell, and Zanetti—all over 10,000 feet high.
On his Alaska Expedition from 1905 to 1908, Sheldon collected specimens of the caribou (Rangifer tarandus), Alaska moose (Alces alces), white sheep (Ovis dalli), snowshoe hare (Lepus americanus), and lemming (Lemmus trimucronatus yukonensis) for the U.S. Biological Survey and U.S. National Museum (Smithsonian Institution), both in Washington, D.C. Camping among the dwarf fireweed along the Savage River in Denali, he performed taxidermy on the skins and preserved the skulls of four different subspecies of meadow mouse, catching the rodents with little homemade traps. A wonderfully precise sketcher, Sheldon also drew vivid illustrations of the wildlife he procured, a time-honored tradition of the Boone and Crockett Club. Regularly Dr. Merriam wrote Sheldon glowing letters about the value of his adventures in the far north to the world of biological conservation. “While his personal interest centered chiefly in the larger game animals, Sheldon nevertheless appreciated the importance of collecting the smaller mammals and took the trouble to trap, prepare, and label large numbers of mice, lemmings, shrews, and other small species, all of which he presented to the Biological Survey for permanent deposit in our National Museum,” a grateful Dr. Merriam recalled of Sheldon in an introduction to The Wilderness of Denali. “These specimens have been of inestimable help to naturalists engaged in defining and mapping the ranges of the smaller mammals and besides have brought to light a number of species previously unknown. And it should be borne in mind that while the major part of his field work was done in Alaska and Yukon Territory, he also made important collections and field notes in British Columbia, Arizona, and northern Mexico.”32
Perhaps Sheldon’s greatest pieces of writing, in hindsight, were his flawless essays on Hinchinbrook and Montague islands (published as chapters in The Wilderness of the North Pacific Coast Islands). Both large barrier islands are located between the Gulf of Alaska and Prince William Sound. They are what Martha’s Vineyard and Nantucket Island are to Cape Cod, but thicker with wildlife. What interested Sheldon about these islets were the vast families of brown bears. (Along Alaska’s coastal waters they were called brown bears; those living in the interior were grizzlies.) As the Japanese Zen poet Basho- had written, “To learn about the pine, go to the pine. To learn about bamboo, go to the bamboo.” To learn a
bout brown bears, Sheldon regularly visited these offshore islands of Prince William Sound. There was a profusion of bears on the islands around every puddle and bend. Sheldon was determined to accurately count their distribution numbers; accurate data would be the first step toward saving the bears.33
“No sight in the American Wilderness is so suggestive of its wild charms than that of the huge bear meandering on the mountain-side, or walking on the river-bank, or threading the deep forest,” Sheldon wrote. “He who still retains his love for wild nature, though accustomed to the sight of wild animals, and surfeited in some degree with the killing of them, feels a lack in the wilderness—perhaps the loss of its very essence—when, tramping about in it, he knows that the bear, that former denizen of its depths, is there no more—exterminated forever.”34
What amazed Sheldon most about the Alaskan brown bear was its massive head, which, incongruously, had inconspicuous ears and tiny eyes. In the East, zoologists thought of Alaska’s bears as having fur of a single color. But Sheldon found that these bears varied from pale tan, sandy, gold, silver, and cinnamon to all shades of dark brown and black. Because of their color variations, Ursus arctos demanded a lot of careful biological scrutiny. Owing to Sheldon’s research, for example, the Biological Survey learned that the bears from coastal Alaska were much darker and more uniformly colored than those found in the interior (which had pale-tipped guard hairs). Furthermore, Sheldon inventoried everything these brown bears ate, including grasses, tender shoots, wildflowers, tree roots, tubers, mosses, willows, and especially berries. While these solitary (except during breeding season) bears occasionally grubbed for insects, larvae, and eggs, they were unable to digest coarse forage very well.35 By cutting out the molar of a shot grizzly, then counting the annual rings of cementum, Sheldon could tell the age of a bear. Whenever he ran into a successful bear hunter, he asked for a molar.
Both Sheldon and Merriam were determined to oversee the most comprehensive inventory of Alaska’s brown bear population ever undertaken. They were convinced that zoologists hadn’t properly identified subspecies of brown bears like Kodiaks. Sheldon was Merriam’s “bear man” in northern Canada and Alaska, trying to understand the range of brown bears, in particular. On Montague and Admiralty islands, he slept in an open canvas shelter with his wife, staying warm under reindeer skin robes. “I note that you give Ursus horribilis as mainly Rocky Mountains,” Sheldon wrote to Merriam. “These scarcely touch Yukon Territory, except north of the Pelly River and they extend well up the Mackenzie. Ursus horribilis is confined to the territory East of the Lewis and South of Steward. But west of the Lewis toward the Alsek River and the White River, close to the coastal ranges I have always thought that the grizzly there resembled those of the Alaska range (alascensis). There is one skin from that district in your collection and two female skulls. Therefore I had Yukon Territory divided up into three regions possibly. Urses phaeonix, ogilves region north of latitude 64—horribilis in district southeast of Yukon Rivers and alascensis inside St. Elias and other coast ranges north.”36
For all his skills as a naturalist, Sheldon was unusual because he enjoyed lonely reveries amid the spruce, often not seeing anyone else for weeks (that is, when his wife wasn’t along). Sheldon shot, with his .22 rifle, a wide range of coneys, marmots, shrews, and ground squirrels for the Biological Survey to analyze. On one Alaska-Yukon trip, Sheldon coincidentally bumped into the world-famous British hunter Frederick Selous, who was collecting for the British Museum. For six weeks, the pair trekked through the far north together, discussing South African game and Alaskan bears. Selous was sixteen years older than Sheldon but, like everybody else, was charmed by Sheldon’s show. They became lifetime friends. When Selous died in 1917, Sheldon wrote to Roosevelt about creating an impromptu memorial to the great British conservationist. “Will you bring the matter up,” Roosevelt wrote to Sheldon, “before the Boone and Crockett Club?”37
But the outdoors life that Sheldon led had drawbacks. In Alaska, for example, the plague was mosquitoes. There are more than 3,000 species of these insects, and at times it seemed that all of them had decided to hold a revival meeting or a roundup in Alaska. When Sheldon studied paleontology as a boy, he learned that mosquitoes had been around to buzz and bite the dinosaurs. Scientists would in coming years find mosquitoes trapped in amber (petrified sap) in a tree fossil more than 38 million years old. During the summer months, swarms of mosquitoes attacked Arctic Alaska’s four caribou herds, forcing the Porcupine herd to migrate 700 miles to escape them. If an Eskimo hunter killed a caribou in summer with a spear or arrow, the carcass would be blanketed by mosquitoes within seconds. There were other true flies in Alaska—crane flies, midges, and gnats—but it was the mosquito, wings beating between 250 and 600 times a minute, that became the bane of outdoorsmen, considered a hazard as menacing as wind, sleet, and snow.

What haunted Sheldon, making him seethe with anger, was the gradual diminution of the larger mammals such as Dall sheep, moose, and deer as a result of market hunting across the tundra-covered valley. Sometimes, even when he was hungry and miserable, Sheldon nevertheless counted and collected for the Biological Survey. Only the thick swarms of biting flies and insomnia during the summer solstice really hindered him. Driven by his love of the outdoors, Sheldon, when the creeks were down and the trails melted out, kept biological diaries of his pioneering wildlife observational research on the northern slopes of the Alaska Range. “Complete enjoyment of the wilderness,” Sheldon wrote, “needs periods of solitude.”38 Being alone at a high altitude gives a person plenty of free time to think. Sheldon began dreaming of the Denali wilderness as a national park—the largest in the system, millions of protected acres. Karstens’s journal entry of January 12, 1908, recorded Sheldon’s first hope that the U.S. government would maintain Denali National Park as a quasi-wilderness area (i.e., roadless).39
The McKinley River was the longest and widest of hundreds of glacier-fed rivers, streams, and creeks. Everywhere a visitor looked, there were braided brooks gurgling across the wet tundra. More than twenty ridges were involved in the drainage of the McKinley River. With his loyal packer Harry Karstens (nicknamed “the Seventy-Mile Kid” because he had once mined a claim on Seventy Miles Creek outside Dawson City), Sheldon built a weatherproof cabin along the Toklat River, located opposite the mouth of present-day Sheldon Creek (named in his honor). From the start, they split plenty of firewood to prepare for the subzero winter. At a trading post they acquired roof shakes and a small keg of nails. Using their lean-to shack as a base camp, Sheldon began wandering around the Denali wilderness. Head down, he struck out into the high-velocity wind, with gun, pad, and pencil. He was a man in his element. It sickened Sheldon that residents of the Kantishna region north of McKinley were mass-butchering game while building the Alaska Railroad.40 It also sickened him to see market hunters butchering Dall sheep to put meat in the pots of mining camps in the Savage, Teklanika, Toklat, and Sanctuary river valleys. Much of this meat was fed to the sled dogs. Much like annual tree rings, the indented lines on a ram’s horns, some spreading as much as three feet across, indicated the Dall sheep’s age. Sheldon feared the species was headed toward extinction. Even the U.S. Army infantrymen stationed in Alaska at Fort Gibbon at Tanana and Fort Liscum near Valdez considered the sheep butchery repugnant.
Throughout 1907–1908 Sheldon, like a new John Muir, had shared campouts with the Chilkat (in southeastern Alaska). His journals also indicate encounters with the Minchumina, Nenana, and Tanana.41 The Ivy Leaguer looked as if he had been born and raised amid Alaska’s varied habitats—glaciers, mountains, tundra, grasslands, wetlands, lakes, woodlands, and rivers. He wore rawhide moose snowshoes and traveled in forty-foot-long bark canoes. In his log cabin, whose roof was scarcely higher than his head, he scribbled furiously about the great round moon, silvery waterfalls, icy fjords, and torrential rains. Despite all the precipitation, Sheldon worried constantly about brushfires. Ever since the U
.S. Forest Service was created in 1905, men had been paid decent wages as fire lookouts. Sheldon hoped to raise funds in New York for hiring more lookouts for Alaska. “Alone in an unknown wilderness hundreds of miles from civilization and high on one of the world’s most imposing mountains, I was deeply moved by the stupendous mass of the great upheaval, the vast exterior of the wild areas below,” Sheldon wrote, “the chaos of the unfinished surfaces still in process of molding, and by the crash and roar of the mighty avalanches.”42
As reflected in Karstens’s remembrances, Sheldon was determined to see Mount McKinley saved as a kind of Grand Canyon of the north—a protected American wonder, a true wilderness area untouched by axes or construction crews where a citizen could go and get lost. To his mind only one two-lane road should be allowed to cut through the park. Mount McKinley, he said, was an inheritance for his grandchildren.43
When Sheldon returned to New York before Christmas 1908, invigorated by the stinging snows of Denali, he almost single-handedly launched a campaign to create a national park around Mount McKinley. He was the best cheerleader wild Alaska ever had. The bird flocks in the area, he said, were loud enough to throw an orchestra out of tune. The salmon-rich rivers had the cleanest, purest water that ever rushed over rocks. To see a double rainbow over the Teklanika River at summer twilight was proof that the world had a Creator. Painting word pictures, Sheldon told his audiences about seeing Mount McKinley free of clouds, lording it over the adjacent snow-clad summits, as grizzly bears patrolled the base. The great Muldrow Glacier falling down the eastern side from the snowfield between the two domes, he claimed, was one of the great sights in nature. What worried Sheldon was that hunters were slaughtering more and more game to feed mountain-ringed towns such as Nenana, Kantishna, and more distant Fairbanks. As a purist with regard to nature reserves, he disdained the filthy backwoods stump mills, placer operations, and forest “units” earmarked for cutting. Once the railroad came, connecting Seward to Fairbanks, additional market-hunting syndicates would patrol the Denali wilderness and kill everything that moved.44
