Collecting Rocks in Michigan

There is a 25lb annual limit on the collection of rocks, minerals and fossils from state-owned land and lands held in the public trust in the state of Michigan. Collecting artifacts and antiquities of any kind (including shipwreck material and native artifacts) from state and public trust lands is illegal. State-owned lands refer primarily to state parks. Lands held in the public trust by the state of Michigan include all Great Lakes shorelines up to the Ordinary High Water Mark (OHWM) and all bottomlands. Bottomlands include all sand/soil/rocks beneath the water of the Great Lakes and all navigable rivers and lakes. Excluded from this list are all regions under federal management. <a href="https://craigmcclarren.medium.com/collecting-rocks-in-michigan-aa5c2d6567e9">Website</a>
