Bighorn National Forest
Ten Sleep Canyon. (307) 674-2600

You are standing at the bottom of Ten Sleep Canyon near the western edge of the Big Horn Mountains. The steep rocky cliffs were the native territory of the Bighorn sheep. Disease and the activities of human and livestock have led to their eventual disappearance. They have been reintroduced to this forest through cooperative efforts of the U.S. Forest Service and the Wyoming Game and Fish Department.

Lewis and Clark’s expedition was the first organized exploration into the area. The great numbers of Big Horn sheep noted in their journal in 1808 gave the river, basin, mountains, and National Forest its name.
