About this map

The high desert plains of Elmore County meet the rising timber of the Boise National Forest in this 1990 survey. Centered on the growing hub of Mountain Home, the map details a landscape defined by water management and military infrastructure, from the massive Anderson Ranch Reservoir on the South Fork Boise River to the sprawling Mountain Home Air Force Base and its associated Mountain Home Small Arms Range.

Transit through the region is anchored by the Union Pacific railroad and Interstate 84, connecting remote outposts like Mayfield and Hill City. The terrain transitions from the volcanic geology of the Crater Rings and Slaters Flat in the west to the high, fertile reaches of the Camas Prairie and Mount Bennett Hills in the east. Scattered reservoirs, including Little Camas Reservoir and Long Tom Reservoir, illustrate the critical role of irrigation and storage in this arid environment.
