2017 Map of Split Rock

About this map

Split Rock and the nearby Butte Crater dominate the northern landscape of this corner of eastern Idaho. This 2017 survey details a volcanic and high-desert environment defined by sparse infrastructure and significant geological formations. The boundary between Clark and Fremont counties bisects the western portion of the map, carving through an area largely shaped by natural contours rather than dense settlement. A handful of primitive routes provide the only land access through this terrain, including Red Rd and Ice Cave Rd, which trace the low-lying areas between ridges and craters. The township and range system here, including t11n r39e, reflects a landscape partitioned for public land management and conservation, where the evidence of past volcanic activity remains the most prominent feature of the local geography.
