1951 Map of Graham Ranch

About this map

The Oregon Trail cuts a historic path across this high-desert landscape in central Wyoming, following the southern banks of the Sweetwater River and Ice Slough. This 1951 survey, developed as part of the Department of the Interior's Missouri River Basin project, documents the early 1950s ranching and extraction economy centered around Graham Ranch. Mineral interests are well-defined, with several sites including a Jade Prospect and multiple Jade Mine (Inactive) locations scattered across the northern hills. Water management for the arid region is represented by the Emigrant Ditch and various smaller channels, while industrial progress is marked by an Oil Well (Aban'd) and a regional Pipe Line. The varied topography rises from the river valley toward the prominent Sweetwater Rocks in the southeast corner.
