1966 Map of Beaver Basin

About this map

Middle Mountain and Cold Spring Mountain dominate this high-altitude landscape in northwestern Colorado, where the 1966 terrain is defined by a complex network of seasonal drainages and springs. The map documents the high-country grazing infrastructure of the mid-20th century, specifically the Buckley Cow Camp near the headwaters of My Valley. This remote corner of Moffat County serves as a transition point between state lines, bordering the Utah State Line to the west and the Wyoming-Colorado border to the north. Numerous water sources such as Spitzie Spring, Talamantes Creek, and Antelope Spring are crucial markers for local land use and stock management. The presence of Rocky Reservoir and a system of jeep trails indicate the essential, though sparse, human presence required to manage these upland meadows and peaks like Diamond Peak.
