About this map

High plains ranching and water management define this landscape on the border of Goshen Co Laramie Co during the early 1960s. The map illustrates a complex network of irrigation infrastructure essential to the region's agricultural viability, including the Coad Ditch, Petsch No 1 Ditch, and the primary Petsch Reservoir located in the southern portion of the quadrangle. These man-made watercourses redirect the natural flow of Horse Creek and its various tributaries like Bushnell Creek and Kellehan Creek.

Family holdings are clearly marked through several established landmarks, such as Gregory Ranch in the northwest and Scoon Ranch further south. To the east, the Union Pacific railroad corridor runs parallel to a pipeline and the winding Stinking Water Creek. This survey provides a precise look at the land use and drainage patterns of the Wyoming frontier before modern development, captured during the Missouri River Basin development program.
