About this map

Modoc National Forest dominates this high-altitude landscape, where the management of water resources is the primary footprint on the land. The presence of numerous engineered catchments like McGinty Reservoir, Green Spring Reservoir, and Crowder Mountain Reservoir reflects a systematic effort to capture runoff across the arid terrain of Modoc County. These reservoirs are often situated at the terminus of drainages or within basins like Rimrock Valley, serving as vital infrastructure for the surrounding rangeland.

Boundaries of the X L Ranch Indian Reservation border the eastern edge of the quadrangle, where the terrain descends toward the flats. High points such as Crowder Mountain provide vantage points over a network of springs, including McLain Spring and Pine Spring, which have likely served as consistent water sources for generations. The map reveals a land defined by its geology and the careful husbandry of its intermittent water supply in the late twentieth century.
