About this map

San Luis Valley and the towering Sangre de Cristo Mountains define this 1988 U.S. Geological Survey portrait of southern Colorado. The map traces the historical path of the Rio Grande as it flows south through the Alamosa National Wildlife Refuge, passing early settlements like Alamosa and San Luis. To the east, the dramatic transition from the Wet Mountains to the high plains is marked by the course of the Purgatoire River and the industrial activity around Trinidad.

Regional transportation networks are heavily detailed, featuring the corridors of the D & R G W RR and the A T & S F Ry. Significant water management features, including the Sanchez Reservoir and the Cucharas Reservoir, illustrate the critical importance of irrigation in this high-altitude landscape. Researchers can locate numerous small communities such as Viejo San Acacio, Chama, and Gardner, which preserve the cultural geography of the region before late-twentieth-century shifts.
