1993 Map of Ash Valley

USGS Topo · Published 1996

About this map

Ash Valley is defined by a complex hydraulic landscape of ditches, levees, and reservoirs at the base of Knox Mountain. This 1993 revision, conducted by the U.S. Forest Service, illustrates the ranching and resource management character of northeastern California. Evidence of local history and land use is found in features like Fleming Sheep Camp and a small Cem located near the center of the valley floor. Water remains the primary shaper of human activity here, with Ash Creek feeding into a network of managed water sources, including Holbrook Reservoir and Spooner Reservoir. The western portion of the map transitions into the Modoc National Forest, where the terrain rises toward Oxendine Spring and Diaz Spring. Several small pits and a Gravel Pit suggest localized mineral extraction or road maintenance during this period.
