At the bottom of both trenches there was a brown, moderately decomposed and compacted peat. The peat contained poorly preserved shells and clams and some seed pods were visible. Peat samples have been submitted to Drs. Don Schwert and Allan Ashworth, Geology Department, North Dakota State University, for detailed analysis and identification of insect remains.
