1990 Map of Washington Mountain

USGS Topo · Published 1990

About this map

The Pit River cuts through this high-desert landscape in northeastern California, where the Warm Springs Valley meets the timbered slopes of the Modoc National Forest. This late-twentieth-century record shows the area just as modern accessibility began to intersect with long-standing ranching and forest uses. Key landmarks include the Canby Bridge crossing and the Howards Gulch Campground, providing a look at the outdoor recreation infrastructure of the era. The terrain is defined by prominent volcanic features such as Washington Mountain and Westlake Butte, alongside isolated landmarks like City Rock. Evidence of local industry and resource extraction is visible in the various Borrow Pits and a Cinder Pit scattered across the quadrangle, while seasonal water sources like Gosch Spring reveal the hydrology critical to this arid environment.
