2020 Map of Jim Sage Canyon

About this map

The Upper Raft River Valley in southern Cassia County is defined by a network of drainage systems and vital water sources that sustained ranching in this high-desert environment. The Raft River serves as the primary hydrological feature, fed by numerous seasonal and perennial flows including Almo Cr, Grape Cr, and Edwards Cr. This 2020 survey illustrates the complex topography of the eastern slopes, where the rugged Jim Sage Canyon and Womack Canyon descend toward the valley floor. High-elevation water points like Jim Sage Spring, Womack Canyon Spring, and Reed Spring are critical landmarks for those tracing the history of land use and livestock movement. The mapping of The Narrows and the transition into Dry Canyon highlights the geographical bottlenecks that influenced the development of local roads like Narrows Rd and EY Rd.
