1979 Map of Shoshone Ice Cave

About this map

Lava flows dominate this Idaho landscape at the intersection of Camas, Blaine, and Lincoln counties. The geological character of the region is defined by volcanic features like Black Butte Crater and the notable Shoshone Ice Cave, which sits alongside several other subterranean caves. This arid environment was heavily modified for agricultural use during the late twentieth century, as evidenced by a complex irrigation network including the Bypass Canal, Richfield Canal, and a prominent Siphon. The Union Pacific railroad corridor cuts across the terrain, passing through the small settlement of Burmah in the southeast. Water management is central to the area's development, with the Big Wood River feeding a series of named impoundments such as Magic Reservoir, Trestle Reservoir, and Culvert Reservoir. The map reveals the infrastructure required to sustain life and transport in this distinct basalt-strewn territory.
