1991 Map of White Rock Canyon

USGS Topo · Published 1991

About this map

The Santa Rosa Range dominates this portion of the Humboldt National Forest, where the high desert terrain is defined by a network of drainage systems including Willow Creek and Flat Creek. This 1991 provisional map, based on aerial photography from the mid-1980s, reveals a landscape primarily managed for resource extraction and ranching. Multiple labels for Prospects are scattered across the slopes, particularly near the South Fork Flat Creek and the headwaters of White Rock Canyon, indicating mineral exploration typical of the Nevada backcountry. The presence of Flat Creek Ranch in the northern reach provides a rare point of established habitation in an otherwise uninhabited wilderness of canyons and high peaks like those found along Skull Creek.
