Coldwater Spring, Natural spring at Fort Snelling, Minnesota, US.
Coldwater Spring is a natural water source at Fort Snelling that flows continuously from limestone bedrock, releasing water daily at a steady rate. The water emerges from deep geological formations and maintains consistent conditions year-round.
The United States Army built formal waterworks at the spring during the 1880s, including a springhouse and storage structures that still stand. These structures show how the military developed the site for its strategic location.
The Dakota named this spring Mní Ówe Sní and held it sacred for its healing waters. Native peoples gathered at this location where two rivers meet, making it a place of spiritual importance.
The site is accessible through maintained walking paths that lead past historic structures and through restored prairie areas. You can explore the grounds at your own pace and observe wildlife and plants along the way.
The water flows without freezing even during harsh winters, a feature that has intrigued visitors for generations. This happens because the source originates from ancient rock layers deep underground that retain enough heat to keep the water flowing.
