About this map

City of Rocks dominates the southern landscape of this 1986 survey, marking a geologically complex region along the border of Camas and Gooding counties. The terrain is defined by a dense network of hydrologic features and high-altitude landmarks, most notably Mormon Reservoir in the north and the prominent peak of Fir Grove Mountain. This era of the Idaho backcountry shows a reliance on dispersed water sources, with numerous named springs such as Simms Spring, Cow Heaven Spring, and Big Mike Spring providing vital points of reference for land use and navigation.

Transportation through this area follows the natural contours of drainage systems like Cottonwood Creek and Mc Kinney Creek. The map records several named plateaus and elevations including Bowman Flat, Connet Flat, and Wrangle Hill, which suggest historic grazing or transitional zones between the canyonlands and the higher ridges. The detailed rendering of Bird Canyon and Timber Gulch illustrates the steep, broken nature of the land before it descends toward the southern formations.
