Where to Find Petoskey Stones in Michigan | Michigan<\/a><\/p>\n\n\n\n

Petoskey stones are fossilized coral from the Devonian period, found along the shores of Michigan, especially the northern coast<\/mark>. You can find them by looking for their distinctive hexagonal pattern, which is most visible when the stone is wet. Therefore, the best times to hunt are after a storm or early morning at dawn or dusk. Popular spots include Petoskey State Park<\/a>, Fisherman’s Island State Park<\/a>, and various beaches around Charlevoix<\/a>. They can also be found from Traverse City<\/a> northwards along the coast. <\/p>\n\n\n\n

Formed from fossilized coral that became a rock millions of years ago, then was broken up and rounded by glaciers and lake currents<\/mark>. First, during the Devonian period about 350 million years ago, the coral polyps died and their skeletons were fossilized, replaced by minerals. Later, glaciers scoured these fossil-bearing bedrock. They chipped off pieces and deposited them in what is now northern Michigan. Finally, the constant movement of glaciers and the action of waves on the shores of the Great Lakes smoothed and rounded these fragments. This created the finished stones seen today. <\/p>\n\n\n\n
