One of the Baltic Mine's three (!) powder houses, as viewed from the inside. We found this while looking for a totally different powder house. Then, we found another one -- also not the one we were looking for. By the time we found the right one, it wasn't that surprising any more!
The powder house is pitch black and smelling of ancient dust. It was surprisingly clean of graffiti and junk. Taken on the first day of this year's Copper Country Explorer weekend.
