Michigan’s State stone is the Petoskey stone. There is also a town in Michigan called Petoskey. Both are named after the Ottawa chief named Chief Petosega. The stone is part of a fossilized six-sided coral bed from ancient seas, with circle or striped patterns. They are found along the north western Michigan shoreline of Michigan’s Mitt (the Lower Peninsula) of Lake Michigan, most often in the spring (April or May) when the winter sea churns up the lake’s bottom and brings the stone ashore. Even knowing these facts, it took me years to find one of these treasures. Here is one I bought, all polished up:
I’ve seen people in rubber boots and pronged garden claws, and bags, buckets or even wagons in which to place their finds. These are the professional stone seekers. I’m barely in the Amateur’s Club. I casually look for them when I go to beaches. Each time I find one “in the Wild”, which is not very often at all, I feel like I’ve won a prize. I believe that my joy with finding just one Petoskey stone outshines the relentless beach-prowling pros.
In the photo below is part of the reason they are hard to find. Can you spot it?
It’s the ordinary oval-type one right in the center of the photo. Here’s the stone after I’ve turned it over:
See the circular pattern. Tricky stone! Often plain on one side, with the treasure revealed on the other. Win!
So if you ever find yourself on the northwestern Michigan coast line in the spring, keep your eye out for Michigan’s state stone, the Petoskey stone.
And here are three more of my lovely treasures:
