During the last three years several new deep wells have been drilled in Iowa and accurate sets of well cuttings have been studied. This material indicates the presence of bedded gypsum both in the forms of selenite and anhydrite in formations below the Ste. Genevieve and above the Kinderhook. It is suggested that the horizon is a part of the Warsaw formation and represents an interior saline basin of central Iowa. The details of the well logs of the intervals involved are included in the discussion.
