2015 Map of Black Lassic

USGS Topo · Published 2015

About this map

Six Rivers National Forest dominates this high-altitude landscape along the border of Humboldt and Trinity counties. The terrain is defined by the steep drainage systems of the Little Van Duzen River and the W Fork Van Duzen River, where the peaks of Black Lassic, Red Lassic, and Signal Peak rise as prominent landmarks. This 2015 survey reveals a wilderness area marked by curiously named features such as Perry Salt Log and Coffee Pot, suggesting a history of seasonal grazing or early forest management. The presence of Buck Pasture and several springs, including Goat Spring and Alder Spring, further indicates the historical importance of water sources in this remote mountainous region. Access is limited to forest routes like Forest Rte 1507 and Alderpoint Rd, which navigate the complex topography of Swayback Ridge and Mule Ridge.
