1993 Map of Big Swamp

About this map

Ash Creek State Wildlife Area dominates the central portion of this landscape, where the hydrology of Big Valley creates the extensive wetlands of Big Swamp. The map details a complex system of water management, including a prominent Levee, several canals, and numerous water sources like Service Spring and O'Neals Springs. Cultural history is anchored by Lookout Rancheria and the settlement at Hays, while a lone Cemetery and various Storage Bins suggest the agricultural and community foundations of the region in the early 1990s. The northeastern corner transitions into the high-elevation terrain of Modoc National Forest, marked by Barber Ridge and Major Canyon. Geothermal features are also present, noted by Kellog Hot Springs and other Hot Springs near the southern Modoc Co Lassen Co boundary.
