2010 Map of Split Rock

About this map

Split Rock stands as a focal landmark in this high-desert portion of Fremont County, where the landscape is defined more by its rugged access routes than by dense settlement. The area's network of primitive thoroughfares, including Red Rd, Crooked Rd, and Ice Cave Rd, hints at a terrain shaped by volcanic geology and remote rangeland management. This 2010 survey by the U.S. Geological Survey provides an intricate look at the topographic contours of the Snake River Plain, where naming conventions like Ice Cave Road point to the distinct subterranean features common to this basalt-dominated region. The map captures a moment of modern land use in a corner of Idaho where geographic isolation remains the primary characteristic of the land.
