1990 Map of Cathedral Rocks

USGS Topo · Published 1991

About this map

Smith Prairie dominates the northern landscape of this Elmore County region, characterized by a high plateau that transitions into the steep canyon of the South Fork Boise River. The river winds through the southern half of the map, crossed by the Danskin Bridge and bordered by the Boise National Forest. The presence of the Smith Prairie Landing Strip, a Radio Facility, and numerous prospects suggests a remote area managed for both resource extraction and backcountry access. Geological landmarks like the Cathedral Rocks, Steamboat Rock, and a notable flow of Lava define the terrain's character. Small traces of human activity appear in the form of a Cem and the settlement of Horse, while a complex system of water management is visible through a labeled Ditch network across the prairie.
