About Us

Our Story

Michigan Rockhounds began as a group with a goal: to engage and educate Michiganders on the geological history of the mitten state.

Our focus is on creating open resources with the philosophy that education should be more readily accessible. And so, with the help of like-minded content creators, geologists, and fellow staff, the community grew into what it is today.

Our Community

Michigan Rockhounds grew from a Facebook group of rockhounding enthusiasts. In one year of its inception, the group grew from 60 members to 60,000, and we’re still growing!

On our Facebook page, our team of admins and moderators stay engaged with members by helping ID their finds, share advice, and answer questions. But best of all — we can geek out about rocks together!

Our Mission

Michigan Rockhounds mission is to engage, educate, and uplift the rockhounding community in Michigan.

We’re fostering an engaging community focused on science education. We believe that all knowledge should be openly shared; there should be no secrets to polishing or collecting locations. We’re here to empower our community to have the best experience collecting beautiful rocks across the Great State of Michigan.
