1978 Map of Black Lassic

USGS Topo · Published 1978

About this map

The high ridges of the Six Rivers National Forest define this 1970s landscape, where the Humboldt Co and Trinity Co line follows the drainage divide between the Van Duzen River and eastern basins. This terrain is anchored by a trio of prominent peaks: Black Lassic, Mt Lassic, and Red Lassic. These summits loom over a network of seasonal water sources and trails, including Alder Spring and the Dry Lake area.
