USGS Topo · Published 2021About this map
Six Rivers National Forest dominates this landscape along the border of Humboldt and Trinity counties, where the terrain is defined by dramatic peaks and high-elevation meadows. The Little Van Duzen River and its numerous tributaries, including Black Lassic Cr and the W Fork Van Duzen River, carve deep drainages between prominent landmarks like Senteney Rock, Signal Peak, and the namesake Black Lassic.
