Mines Museum, home to one of Colorado’s two Goodwill moon rocks collected during the Apollo 17 mission, had its beginnings in 1874 with the collection of geologist, Arthur Lakes, and includes the historic Colorado State Mineral Collection created by the Bureau of Mines in the 1890’s. The museum serves as the state repository for Colorado’s mineral heritage and showcases the most extensive public collection of minerals from Colorado.

Land Acknowledgement

It is important to understand the longstanding history that has brought us to reside on this land as an institution of higher learning and to seek to understand and acknowledge our place within that history. We wish to recognize that we reside in the ancestral lands of the Ute, Cheyenne, and Arapaho people of Colorado. We also acknowledge the 48 contemporary tribal nations tied to the lands that make up the state of Colorado and the lands we call Colorado.


For those unfamiliar with the practice, it is a small gesture of recognition of peoples, cultures, and acknowledgment that seeks to speak against the invisibility and erasure faced by Native peoples from their homelands—in this context, especially in education– and to consider how we can each, in our own way, move forward informed by our collective history and commit to a more equitable present and future.
