About this map

Spencer lies at the heart of this high-altitude landscape in Clark County, positioned where the drainage of Beaver Cr cuts through the foothills of the Targhee National Forest. The map documents a classic Western transportation corridor, with Interstate 15 and Old Hwy 91 tracing the natural path carved by the canyon. To the north and west, the terrain rises into the forest lands, marked by the deep incisions of Huntley Canyon and several branches of Dry Creek.

Evidence of the region's volcanic and hydraulic character is visible in landmarks such as The Crater and Bed Springs Butte in the southeastern quadrant, while Threemile Reservoir manages water resources in the higher elevations. The layout of rural routes like Zweifel Rd and Sky-Line Rd illustrates the interface between the open range and the protected timberlands, providing a clear view of the ranching and forestry infrastructure that sustains this portion of Idaho.
