The high desert landscape of the Warner Mountains straddles the Oregon California border in this 1993 revision, showcasing a complex water management system in a semi-arid region. Irrigation infrastructure is prominent, with the Spoil Bank, Ditch, and several check dams regulating flow into the Cow Head Lake basin. This seasonal lake bed, along with nearby Lake Annie and Big Mud Lake, defines the local geography at the edge of the Surprise Valley.
