1966 Map of Sentinel Peak SW

About this map

The Ute Mountain Indian Reservation covers the majority of this mid-1960s survey, revealing a landscape defined by deep drainage systems and early industrial activity. The Mancos River flows across the southern portion of the sheet, while major ephemeral channels like Cowboy Wash and Aztec Wash carve through the arid terrain. For those interested in archaeology and historical land use, the presence of Indian Ruins near the river indicates the long-term habitation of these canyons. The map also documents a modern layer of development, showing a prominent Pipeline cutting diagonally across the reservation alongside scattered energy infrastructure such as Well No A-4 and several designated drill holes. This intersection of ancient sites and 20th-century resource extraction highlights the changing utility of this region in Southwest Colorado.
