Where To Find Petoskey Stone In Michigan

Petoskey Stone is a type of fossilized coral that can be found along the beaches and in the shallow waters of the Great Lakes. It’s prized by rock collectors for its unique appearance and history.

The stone features distinctive patterns of hexagonal cells that are remnants of the coral polyps that lived over 350 million years ago in a shallow sea that covered what is now Michigan.

As the corals died, their skeletons were left behind and were eventually buried by layers of sediment, which over time turned into the limestone rock formations that are prevalent in our state today.

The beaches of Traverse Bay is our favorite place to look for Petoskey Stones

The limestone rock formations that make up the beaches of Traverse Bay were formed over millions of years, and as the rocks erode, they release these fossilized coral. These stones are often polished and smooth, making them easy to spot among the other rocks and pebbles along the beach.
