About this map

The Oregon Trail cuts through the high desert landscape of Fremont County, following a historic path just south of the Sweetwater River. This 1951 survey records the intersection of pioneer migration routes with early 20th-century ranching and mineral exploration. The Graham Ranch serves as a primary point of human habitation, supported by a network of irrigation systems including the Graham Ditch and Emigrant Ditch, which divert water from the river to the surrounding arid basins.

Mineral wealth is evident along the flanks of the Granite Mtns and northern ridges, where the map identifies a Jade Mine (Inactive) and a Jade Prospect. These labels point to Wyoming's mid-century jade rush, a period when the region was heavily prospected for its distinctive nephrite. Natural features like Ice Slough and Long Creek provide critical water sources in a landscape marked by industrial markers such as an Oil Well (Aband) and a regional Pipe Line.
