DescriptionBecause Native Americans who traversed the Big Horn Basin of Wyoming reckoned time and distance in “sleeps,” this midway point across the Big Horn Basin became known as Ten Sleep.
Range wars between cattle and sheep ranchers—quite common in the West during the 1890s and early 1900s—reached a climax with the Ten Sleep-Spring Creek Raid in 1909. This attack on the camp of an ex-cattleman who had brought a large herd of sheep into Big Horn Basin resulted in an investigation that eventually led to a peaceful arbitration.
Nearby Ten Sleep Canyon, on the western side of the Bighorn Mountains, is an outstanding feature of Bighorn National Forest. Near the mouth of the canyon are a trout hatchery and a fish-rearing station; visitors are welcome at both stations. A scenic section of US 16 runs between Ten Sleep and Buffalo.
