Good to know

  • Petoskey stones are most common on northern beaches, though they also turn up farther south.23
  • They come from the Devonian reef limestones of the Gravel Point Formation, which occur in Charlevoix, Emmet, Cheboygan, Presque Isle and Alpena counties.24
  • Charlevoix stone is the local nickname for Favosites, a tabulate coral with closely packed, honeycomb-like cells.2325

Not allowed

  • Sleeping Bear Dunes National Lakeshore: "it is illegal under federal law to remove stones from the National Lakeshore."26
