About this map

The Emigrant Trail and Lander Cutoff cut across this Sublette County landscape, tracing the historic movement of pioneers through the Wyoming basin. Centered near Big Piney, the map illustrates a complex network of ranching and petroleum infrastructure developed by 1970. The hydrology of the region is defined by the three forks of Piney Creek, where numerous irrigation projects like the Homestake Ditch and Mickelson Ditch draw water toward local holdings.

Resource extraction is prominent along the western edge, where the Ruben Oil Field and the Star Corral Reservoir Oil Field Distribution Canal represent the area's mid-century industrial growth. For genealogists, the Plainview Cem and family-named features such as Mc Ninch Ditch and Reardon Ditch provide specific points of interest for locating ancestral homesteads or early water rights claims in the valley.
