"Clean Up The Mines! volunteers from across the country toured abandoned mines this week. They donned hazardous materials suits at Mount Rushmore and carried a large banner to raise awareness of the 169 AUMs in the Southwestern Black Hills near Edgemont.
This may be one of the reasons the fracking study just released that says in part that western SD sands are not good enough for fracking - too porous. Also, in the areas that have AUM's - the background radiation is too high.
