Michigan has mining history buried across the entire state, but this spot lets visitors dig through it themselves instead of just reading about it behind glass. Choosing Your Ore Pile AdventureNot all ore piles are created equal, and that is exactly what makes this place exciting. You get to choose your digging experience based on your group size and what you want to find. The Single-Person Ore Pile works great for one to two adults over a two to four-hour window. Sluicing And Panning For Copper NuggetsBeyond the ore pile dig, this spot offers something even more hands-on for people who love water-based prospecting.
