The Washburn-Doane Expedition of 1870, which proved a large factor in the creation of the Yellowstone National Park, was marked by one of the most extraordinary incidents in the annals of the American frontier.

Truman C. Everts, a former United States Assessor for Montana, was a member of the party. On September 9, he became separated from it and for thirty-seven days wandered in the Yellowstone wilderness.

Everts was wholly unfit to take care of himself in the wilderness. He was a city man, without experience in the wilds, timid, unresourceful, and very near-sighted. The first day he lost his glasses. The second day, while he was dismounted, his horse took fright and ran away with his traveling equipment. He tried for hours to capture the horse, but failed. Everts was left alone on foot in the rough country south of Yellowstone Lake, without food, gun, axe, blankets, or matches.

He went back to where he had fastened notes upon trees; but these had not been seen by his companions. By this time it was mid-afternoon. Toward evening he realized that he was completely lost.

Without food, fire, or shelter, he passed the night in the depths of a forest. There was a hard frost. Coyotes howled, and lions cried. His overwrought imagination conjured up endless terrors and dangers from the strange and ever-changing sounds of the wilderness.

On the third day out, Everts started off to follow, as he supposed, the direction taken by his companions, but took the opposite direction. He passed near numbers of animals. Finally he came to a small lake around which were many hot springs. In the water were many wild-fowl. He was starving, but had nothing with which to kill game. Fearful as he was of Indians, hunger led him to hope that he might meet them.

The loss of his eyeglasses was calamitous. Out in the lake he saw what he took for a boat coming to land, and he joyfully hastened to the shore to meet it. But when his "boat" took wings and transformed itself into a huge pelican, he was unnerved and almost lost hope.

At this lake he fortunately discovered a species of thistle with large edible roots, and these formed his principal sustenance for weeks. He took up the uncertain fight for primitive necessities. At the lake he became afraid, imagining that a mountain lion was near. He climbed into a tree and remained there most of the night. When at last he descended, half frozen, a heavy September snowstorm was coming on.

To avoid freezing to death, he built a rude shelter of boughs over one of the hot springs. In the boiling water he cooked his thistle-roots. For several days he remained in this shelter; then, realizing that if he stayed longer he might perish in another storm, he traveled on.

Day after day, Everts hoped that his companions would find him. During two weeks they searched diligently, leaving small deposits of food at places where they thought he might pass. They fired guns, put up signs, and lighted fires on the heights; but the rough, wooded nature of the country, and Everts's near-sightedness, made these efforts unavailing. Reluctantly his friends gave up the search and went on; but when they reached a settlement they sent back a rescue party.
