1979 Map of Black Lassic

USGS Topo · Published 1979

About this map

Six Rivers National Forest anchors this 1970s landscape, where the rugged topography of the North Coast Ranges is defined by the three peaks of Mt Lassic, Black Lassic, and Red Lassic. This high-elevation terrain serves as a critical watershed, feeding the headwaters of the Little Van Duzen River and the West Fork Van Duzen River. The map reveals a land utilized primarily for resource management and seasonal use, characterized by numerous jeep trails and high-country landmarks like Swayback Ridge and Freezeout Ridge. Small, isolated camps and outposts such as Dutchman Camp, Summit Flat, and Fingal Ranch dot the wilderness, illustrating the area's history of remote ranching and forestry. Specific family-named or utilitarian features like Senteney Rock and Perry Salt Log provide specific points of interest for local historians and genealogists tracking land use patterns in this corner of Humboldt and Trinity counties.
