1990 Map of Idaho Canyon Spring

USGS Topo · Published 1990

About this map

The Black Rock Range dominates this corner of Humboldt County, defining a landscape of high-elevation springs and deep canyons north of Summit Lake. This 1990 provisional edition, based on earlier surveys and 1980s aerial photography, highlights a region dedicated to conservation and seasonal livestock movement. Large tracts of the Sheldon National Wildlife Refuge and the Lahontan Cutthroat Trout State Natural Area suggest the environmental importance of the local watershed, where Pole Creek and Craine Creek flow through the arid terrain.
