Lassen Volcanic National Park dominates the southern landscape of this mid-1970s survey, showcasing a geological theater of volcanic features including Lassen Peak, Chaos Crags, and Cinder Cone. The eastern corridor is defined by the massive basaltic escarpment of the Hat Creek Rim, while the Pit River carves through the northern reaches near Chalk Mountain. This era captures the region's complex land management across the Shasta National Forest and Lassen National Forest, showing the proximity of tribal lands like the Montgomery Creek Indian Rancheria to established settlements such as Burney. The map reveals a high-altitude wilderness shaped by both fire and water, where the Pacific Crest Trail traverses a terrain dotted with alpine lakes like Manzanita Lake and Snag Lake alongside specialized sites like the Poison Station and Bogard Ranger Station.
