• Abstract:
  A detailed assessment of the mineability of ten potential locations of pozzolans was made. The deposits are all volcanic ash beds within the Lakota Formation, a cretaceous sedimentary rock which crops out as a hogback, which encircles the Black Hills. The most favorable deposit is located about 10 miles south of the Cement Plant at Rapid City. There is very little overburden. The deposit is over 30 ft. thick and could produce 1 million tons from an area less I than 10 acres.
