Why have petoskey stones become so scarce along the Lake Huron shore in the last few years?
They have not. You must know where to find them on lake Huron
shores. If there is a spot near you with loads of rocks in the
water and there are not many waves, stay and look for 5 minutes. If
there is a rocky beach near you and it is wavy look at the rocks
that get wet. By myself, just a few miles south of tawas, I found
363 petoskey stones last weekend and I'm only 13. If you really
want some you can ask me and ill put some more on eBay for you.
Hope I could help, Evan. =D
