About this map

Mountain Home Air Force Base occupies a significant portion of the eastern landscape on this modern Idaho survey, showing the facility’s infrastructure near the high desert borderlands. The terrain is defined by the ephemeral courses of Canyon Creek and Squaw Creek, which cross the high plains towards the Snake River basin. Transport and access follow a rigid grid of rural and service roads, including Simco Rd and Grandview Rd, illustrating the intersection of military operations and regional transit. Historically significant routes such as the Strike Dam Cut Off Rd and industrial features like Gravel Pit Rd suggest the ongoing utility of this arid landscape. The map also delineates the jurisdictional boundaries between Ada, Elmore, and Owyhee counties, providing a precise record of these administrative lines in relation to the local drainage patterns and military installations.
