About this map

The Burnt Lava Flow Geological Area dominates the northeastern reaches of this Siskiyou County landscape, revealing a terrain shaped by volcanic activity within the Shasta National Forest and Modoc National Forest. The map is characterized by a series of significant depressions and volcanic vents, including the prominent Deep Crater and the twin openings of Double Hole Crater. These formations are often associated with subterranean features unique to the region, such as the Deep Ice Caves and Jot Dean Ice Cave.

Human activity is concentrated along the forest roads, specifically Doublehead Rd and Mc Cloud Rd, providing access to the southern settlement of Lakin. The presence of a Cinder Pit reflects the extraction of volcanic materials for local use. For those studying the topographic character of the region, the map traces the elevations of Porcupine Butte and Timber Hill, while the secluded Porcupine Lake offers a rare water feature in this porous volcanic soil.
