1978 Map of Stony Ridge

About this map

The Diamond Mountains dominate this 1970s landscape, marking the transition from high-elevation peaks down to the Honey Lake Valley floor. This era is defined by the significant military footprint along the western shore of Honey Lake, where the Sierra Army Depot occupies the lakeside flats. Small-scale ranching and remote outposts like Clark Ranch and Ophelia represent the sparse settlement patterns of the period, while the Plumas National Forest land is crisscrossed by a network of drainage systems, including Cottonwood Creek and Stony Creek. Numerous named water sources, such as Dinky Spring and Round Mtn Spring, suggest the critical importance of water management in this arid Lassen County environment. Topographical detail captures the steep descents of Wales Canyon and Brockman Canyon toward the valley below.
