The story

How Ten Sleep came to be

From Wikipedia’s history of Ten Sleep.

Read it all →

Ten Sleep was an American Indian rest stop, so called because it was 10 days' travel, or “10 sleeps,” from Fort Laramie (southeast), Yellowstone National Park (west-northwest), and the Indian Agency on the Stillwater River in Montana (northwest). The archeological sites in the area feature artifacts such as arrowheads, pictographs and petroglyphs.

Ten Sleep was also the site of the Spring Creek Raid, one of the last feuds of the West's Sheep and Cattlemen's War. It was there in March 1909 that cattlemen attacked sheep herders and their flock, killing three men and shooting hundreds of the sheep.
