About this map

Six Rivers National Forest dominates this California landscape along the rugged border of Humboldt and Trinity counties. The terrain is defined by a series of prominent peaks, most notably the triplet of Black Lassic, Mt Lassic, and Red Lassic, which overlook a network of high-elevation meadows and ridges. A sparse human presence is marked by primitive encampments and ranching outposts like Dutchman Camp, Fingal Ranch, and the curiously named Perry Salt Log.

Water sources are vital in this upland environment, with the Little Van Duzen River and its various forks carving through deep drainages such as Lost Canyon. Numerous springs are recorded throughout the area, alongside isolated bodies of water like Lost Lake and Dry Lake. The map reveals a land utilized for grazing and seasonal movement, evidenced by place names like Buck Pasture and Summit Flat, and connected by a system of trails and unimproved jeep roads that navigate the complex topography of Mule Ridge and Swayback Ridge.
