Greetings Rockwater et al:
It definitely has a lot of Silica sand in it. The color is what I would call a dusty rose. Bowen, I'm in MO. This is a mineral rich area & one of the theories is that the minerals were pushed here by the glaciers. This is about as far south as they got before receding back north. Don't know if there is any truth to that or not.
Thanks for your input RW. The last big boulder of it I saw was a couple of summers ago. A contractor was clearing trees from power lines along the right of way to the old road near the plantation where these rocks seem to surface. They had cleared back about 15-20 ft from the road. I happened to drive by & saw a big boulder of it sticking up out of the ground. A couple of days later I went back with my rock hammer & shovel but it was gone. Someone had beat me to it!

Good trip but sad, BB. I've given some thought to going in 2020 for the 80th anny but in all reality this was probably my last trip there. So I made a special effort on Wed to ride out to the Crazy Horse Memorial & museum at Custer one last time.
