I recently took a walk in my property in southern michigan and stumbled upon tons(literally) of these shiny silver and gold streaked rocks. Now I'm assuming that it is nothing but pyrite, however I figured I would post some pictures and hopefully get some insight from those with experience. Any...
Im in Menominee County, found dust and specks in my yard, but looking for good sites to search I've heard there is quite a bit in the water (where I work best) anyone with insite to this area?
