USGS Topo · Published 1988About 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.
