Coldwater Spring

Coldwater Spring is a spring in the Fort Snelling unorganized territory of the U.S. state of Minnesota, that is considered a sacred site by the Dakota people, and was also the site of the U.S. Army's Camp Coldwater for troops that constructed Fort Snelling. Coldwater Spring is located on the west bluffs of the Mississippi River directly south of Minnehaha Park and adjacent to Fort Snelling State Park. Waters from the naturally occurring spring flow continuously year round and remain unfrozen in winter months. The spring and surrounding area is managed as a protected historic site and natural park by the National Park Service as part of the Mississippi National River and Recreation Area.
