1993 Map of Rattlesnake Butte

About this map

Warm Springs Valley defines this portion of Modoc County, where the meandering Pit River and its associated water management systems dominate the landscape. Significant infrastructure is visible around the California Pines Airport, including a large residential layout and the Delmorma School near Donovan Reservoir. The area's volcanic and hydraulic character is evident through features like Rattlesnake Butte, Hot Creek Butte, and numerous water sources such as Mary Pete Spring and Portuguese Spring. The map documents a transition in land use, showing a complex network of ditches—including Rattlesnake Ditch and a prominent levee—designed to harness the valley's water resources for the surrounding high-desert plateau. Forested lands of the Modoc Nat For encroach from the east, while the central valley floor is marked by industrial sites like a Cinder Pit and Gravel Pit.
