1980 Map of Red Rock Canyon

About this map

The high desert borderland where California meets Nevada is defined by isolated water sources and sharp elevation changes in this 1980 survey. Running north to south, the boundary between Lassen County and Washoe County cuts through a landscape where survival and land use depend on specific named springs and reservoirs. Features like Sheep Camp Draw Reservoir and Rocky Trail Reservoir indicate a history of ranching and range management in these arid uplands. To the east, the topography descends toward Dry Valley, while prominent landmarks such as Black Mountain, Eagle Head, and Black Knoll provide navigational anchors across the high basin. Numerous seasonal water points, including Rosebud Spring and Mustang Spring, trace the natural drainage patterns of Red Rock Canyon and the surrounding draws.
