About this map

Porcupine Butte rises as a central landmark in this high-elevation landscape within Siskiyou County, where volcanic geology dictates the terrain. The network of Forest Service roads, including the primary Forest Rte 40 and Medicine Lake Rd, provides access to a series of distinctive subterranean and surface features. Significant geological formations like the Porcupine Lava Tube, Half Mile Tube, and the depressions of Double Hole Crater and Deep Crater reveal the area's volcanic history.

The settlement of Lakin sits in the southern portion of the quadrangle, serving as a rare point of named habitation in an otherwise rugged environment. Small water bodies like Porcupine Lake and varied elevations such as Red Hill, Snell Butte, and Stud Hill are mapped with precision, offering researchers a clear view of the complex land management and natural history of this portion of Northern California in the early 21st century.
