Surprise Valley defines the western expanse of this Modoc County landscape, where the ephemeral waters of Upper Lake meet the rising terrain of the Larkspur Hills. This arid high-country environment is marked by essential water sources for ranching and wildlife, including Conlan Spring and the drainage of Schamp Cr. The map reveals a network of rural routes such as Fee Reservoir Rd and Co Rd 7 that navigate the depressions of Poison Springs Canyon and Lieberman Canyon. Significant hydrology is concentrated at Fee Reservoir and the seasonal beds of Big Mud Lake and Little Mud Lake, illustrating how the management of limited water resources shaped the development and land use of this northeastern California territory.
