2020 Map of Split Rock

About this map

The boundary between Clark County and Fremont County bisects this high-elevation volcanic landscape. Dominating the northern reaches of the quadrangle are Butte Crater and the distinct formation of Split Rock, landmarks that guide travelers through this transition between ranges. The terrain is marked by the complex Public Land Survey System grids of Townships 9, 10, and 11 North, revealing how this territory was partitioned for management. Transportation is defined by a series of primitive routes including Red Rd and the aptly named Ice Cave Rd, which suggest the subterranean volcanic features typical of this corner of Idaho. The lack of permanent structures or major waterways emphasizes the area's use for seasonal passage or resource management rather than dense settlement.
