I tell a lot of folks who visit the BH to look for minerals. Lot of interesting rocks with a lot of there. I will not tell you where it is other than on the Iron Mountain Road between the east entrance of Custer State Park and Keystone, but there is a huge vein of Rose Quartz along that road that is easily seen and with the sun shining on it, very beautiful and pretty rare in that kind of volume. Give the kids a prize to the one who spots it (you have to look but it is there)
There are several rock shops in the town of Custer area and a visit to any of them would make a good prize
