2020 Map of Black Ridge Crater

About this map

Black Ridge Crater dominates the southern landscape of this Lincoln County survey, marking a significant volcanic feature within the broader Snake River Plains. The topography is defined by the subtle elevation changes characteristic of this basaltic highland, where the lack of perennial surface water is reflected in the absence of named creeks or springs. This isolation is further emphasized by the sparse road network, consisting primarily of local and four-wheel-drive tracks that navigate the township boundaries of T4S R21E and T5S R21E. The map captures an era of modern land management in Idaho's high desert, where the vast open range of the Snake River Plains remains largely undeveloped, serving as a distinct record of the geologic character and remote wilderness of the region.
