About this map

Klamath National Forest and Shasta National Forest meet in this mid-1980s topographic survey of Northern California. The terrain is dominated by prominent volcanic and geological landmarks, including the namesake shield volcano The Whaleback in the southeast and the distinctive Sheep Rock to the west. The presence of several industrial extractions, such as a Cinder Pit, Gravel Pit, and Sand Pit, indicates the area's utility for road-building materials and geological resources during this era.

A network of 4WD trails and unimproved roads laces across the slopes of Deer Mountain and into the Shasta Valley, reflecting a landscape managed for timber and recreation. The transition between the high peaks and the valley floor is marked by the geological label Andesite, signifying the volcanic character of the Siskiyou County landscape. State Route 97 serves as the primary artery through this rugged region, which remains largely characterized by its national forest boundaries and open natural terrain.
