Fremont

In the uplands west of Yellowstone, mountain streams and warm springs feed the headwaters of Henry's Fork of the Snake River. The waters run through forest and canyons before reaching the broader river plain. Shoshone communities, including mountain people known as Sheep Eaters, were among the inhabitants of this country. After horses spread through the region, Shoshone and Bannock hunting parties travelled through the basin towards Yellowstone and made camps in its mountain valleys.
