Explore the Mammoth Site

The Mammoth Site is a 501(c)(3) nonprofit organization dedicated to the mission of preservation, research, and interpretation of the late Ice Age record found at our site in Hot Springs, South Dakota. We are the world’s largest mammoth research facility and one of the top fossil interpretive sites in North America. Over 60 mammoths (58 Columbian, 3 woolly) have been unearthed, along with at least 87 other Late Ice Age animals.

The Mammoth Site does not receive any ongoing federal, state, or local funding. Admission, donations, and gift shop sales help us continue to tell the story of the late Ice Age.

The History

In June 1974, heavy equipment operator George Hanson was leveling ground for a Hot Springs housing development planned by land owner Phil Anderson. Hanson was grading a small hill when his blade struck something that shone white in the sunlight. Hanson got out for a closer look. What he saw was a tusk, about seven feet long, sliced in half length wise, along with other bones.
