1990 Map of Timbered Crater

About this map

Timbered Crater dominates the western portion of this landscape, a prominent volcanic feature situated at the intersection of Shasta, Siskiyou, and Modoc counties. The terrain is defined by extensive lava flows that stretch southeast toward Ahjumawi Lava Springs State Park and the waters of Big Lake. This 1990 provisional edition illustrates a rugged transition where the Shasta National Forest meets the marshy lowlands of Little Hot Spring Valley. Human presence is sparse, marked primarily by 4WD trails and the small settlement of Schneider near the eastern boundary. The map effectively captures the hydrology of the region, from the high Gassaway Reservoir to the geothermal signatures at Little Hot Spring. Numerous family or local landmarks such as Brushy Butte and Adobe Flat provide specific points of interest for those studying the remote volcanic geology of Northern California.
