1990 Map of Yost

About this map

The small settlement of Yost sits at the foot of the Raft River Mountains, serving as a focal point in this high-altitude landscape where the Upper Raft River Valley meets the northern slopes of the range. Surveyed in the 1980s, the terrain is defined by the complex drainage systems of Johnson Creek and George Creek, which flow northward from the Sawtooth National Forest toward the Idaho border. The map captures a working landscape of resource extraction and seasonal water management, evidenced by numerous adits, prospects, and a gravel pit tucked into the foothills.
