1987 Map of Grouse Creek

About this map

Sawtooth National Forest dominates the northern reaches of this landscape, where the Raft River Mountains and Sawtooth Mountains create a high-altitude border between Utah and Idaho. The map captures a high-desert ranching and transit corridor defined by the Raft River Valley and the expansive Grouse Creek Valley. Small settlements such as Yost, Park Valley, and Rosette are isolated hubs connected by Highway 30, while the southern landscape descends toward the brine of the Great Salt Lake and the shifting terrain of Mud Flat.
