1979 Map of Black Lassic

USGS Topo · Published 1988

About this map

Six Rivers National Forest dominates this mountain landscape along the border of Humboldt and Trinity counties. The terrain is defined by the three iconic summits of Black Lassic, Red Lassic, and Signal Peak, which form a dramatic high-altitude cluster. These peaks shed water into a complex network of drainage basins, primarily feeding the Little Van Duzen River and the various forks of the South Fork Van Duzen River.
