1960 Map of Measel Spring Reservoir

About this map

Shirley Basin and the adjacent Shirley Ridge define this high-altitude livestock and ranching territory in Carbon County. The landscape is characterized by its vital water management features, including the Measel Spring Reservoir and Junction Res, which supported the region's agricultural economy. This mid-century topography reveals a sparse network of ranching infrastructure, such as the Section 20 Reservoir and a lonely Well in the eastern basin, illustrating how water access dictated land use. North of the basin, the terrain drops into Bates Hole, while intermittent drainages like Sand Spring Creek and Sand Creek cut through the arid flats. The inclusion of Sullivan Reservoir further emphasizes the importance of engineered water storage for survival and industry in this portion of the Wyoming interior.
