1980 Map of Black Ridge

USGS Topo · Published 1980

About this map

Humboldt National Forest encompasses the high, drainage-rich terrain shown here in the early 1980s. The map is defined by the prominent Black Ridge and Mahogany Ridge, which separate various seasonal and perennial water systems. A single identified settlement, Cabin, sits in the northwest near the North Fork Creek, while the rest of the landscape is dominated by ranching and transit infrastructure such as the Bradshaw Road and various jeep trails.
