2020 Map of Lyman Pass

About this map

Sawtooth National Forest lands dominate the northeastern corner of this area, marking a transition into the high terrain of the Albion Mountains. The topography is defined by the significant divide between Middle Mountain and the surrounding basins, with the prominent Lyman Pass serving as a natural corridor into Junction Valley. A network of remote water sources and drainages, including Slide Spring, Birch Creek, and Cottonwood Creek, suggests a landscape historically utilized for livestock grazing and movement through the high desert canyons. The presence of Emery Canyon Rd and Birch Creek Rd indicates the primary routes used to navigate these valleys, following the natural contours of Emery Canyon as it cuts through the mountains. This 2020 record documents the hydrography and elevation of a sparsely populated but geographically complex section of Cassia County.
