Emmet County
Little Traverse Bay in Emmet County is the most reliable place in Michigan to find Petoskey stones, the state stone, which are fossilized Hexagonaria colonial coral that show their honeycomb pattern best when wet. Petoskey State Park offers about a mile of sand-and-rock Lake Michigan shoreline, and nearby Magnus City Park adds a free-parking beach within walking distance of downtown. Charlevoix stones and other Devonian fossils turn up in the same gravel.
