Prismatic calcite with low-angle rhomb terminations and associated light purple fluorite. This is a very characteristic calcite from the Ozark-Mahoning portion of the Cave-in-Rock district. Prior to the opening of Harris Creek this would have been considered quite a find from their area of CIR. Minor edge abrasions typical of the era. Mined ca. 1970s. Wayne Fowler Collection. Entered into Ross C. Lillie database as RCL2601.
