Indian Spring

Location: Saguache County
Size: 640 acres
Designated: 1987
Owner: National Park Service

Indian Spring is the largest of the natural cold springs in the San Luis Valley. It lies in the midst of an active, warm climate dune field adjacent to Great Sand Dunes National Monument.  The drainage has been separated from the Rio Grande River for several thousand years, isolating the aquatic fauna. A rare species of tiger beetle and an unusual diversity of wasps, bees and butterflies occur nearby.
