Found it in Rogers City. Tons of amazing rocks/boulders up there, including an absurd amount of petoskeys. There are a few rock slides I go to in the area where you can casually look at the ground and can find half a dozen petoskeys in about 30 seconds. I'm not personally a huge fan of them, but everyone else in Michigan seems to be, so I still grab them sometimes.Very nice local stone...
