Charles Mears State Park Beach — Rockhounding in Oceana County, Michigan

Charles Mears State Park puts almost 2,000 feet of Lake Michigan beach within easy reach in Pentwater, where wave-sorted gravel turns up Petoskey stones and other glacially transported Great Lakes specimens. The shoreline below the ordinary high-water mark is public land, so beachcombing is broadly allowed along the water's edge. It is one of the more accessible west-coast beaches for casual collectors. Reported finds include petoskey stones, agate, fossils. Below: coordinates, access notes, nearby spots, and trip-planning links.
