The North Platte River winds through the high interior of Wyoming on its long course towards the plains. Shoshone and Arapaho people travelled through the wider river country, hunting and maintaining routes across the basins and mountains. By the early nineteenth century, pressure from Crow and Arapaho groups had contributed to Shoshone movement westward. Fur trappers also followed the North Platte and Sweetwater valleys in the 1820s, using them as approaches to South Pass and the Green River country beyond.
