2011 Map of Yost

About this map

Yost serves as the central hub of this high-altitude basin where the Upper Raft River Valley meets the northern slopes of the Raft River Mountains. This landscape is defined by its vital water sources, with numerous named springs such as Callahan Spring, Blyth Spring, and Mahogany Spring feeding a network of drainages including Johnson Creek and Wildcat Creek. The settlement pattern follows these watercourses, with local infrastructure like Strevell Rd and Lynn Valley Rd connecting remote ranching sites and the Yost Cemetery. High-elevation landmarks like Mahogany Peaks overlook the terrain, which transitions into deep cuts such as Browns Canyon and Limekiln Hollow. The map detail captures the specialized geography of the Utah-Idaho borderlands, illustrating how irrigation and topography shaped the development of this secluded mountain community.
