About this map

Cross Mountain and the high plateaus of northwestern Colorado dominate this 1960s landscape, where the Yampa River and Little Snake River carve through high desert terrain. The area is characterized by an extensive system of drainages, including Yellow Cat Wash and Sand Wash, which frame various ranching outposts and remote landmarks. Ranching life is evident through family-named sites such as Sand Wash Ranch, Two Bar Ranch, and Sheridan Ranch, which are connected by a network of unimproved dirt roads.

Prominent elevations like Lone Mountain and Douglas Mountain rise above the surrounding mesas, while Sevenmile Ridge and Peck Mesa provide significant geographic markers. The presence of Thompson Springs and Two Bar Springs highlights the importance of water sources in this arid environment, while features like Clay Buttes and Pigpen Hill reflect the local nomenclature of the mid-century ranching era.
