1993 Map of Big Sage Reservoir

USGS Topo · Published 1997

About this map

Modoc National Forest dominates this high-altitude landscape, where the massive Big Sage Reservoir serves as a focal point for water management and recreation in the high desert. The map shows the infrastructure supporting the reservoir, including the Big Sage Dam and a Boat Ramp, alongside smaller water bodies like Kelley Reservoir and Essex Reservoir. This 1993 revision, based on photographs dating back to 1958, illustrates a land utilized for both conservation and resource extraction, evidenced by the Devils Garden Conservation Camp and scattered sites like a Pit and Prospect near Salisbury Gulch. The network of 4wd tracks and trails connecting Whittemore Ridge and Porcupine Valley highlights the area's role as a managed wilderness area where natural springs such as Mill Springs and Rock Springs remain vital landmarks in an otherwise arid terrain.
