NT 58174 74633 Two transects were cored: (A) north to south on the short axis of the pond at its widest part and (B) east-west along its long axis. Boreholes were made with a 1.0m long, 3.0cm diameter Eijelkamp peat gouge. Because visibility was limited through water, much stabbing with the gouge was necessary at all boreholes to find narrow gaps between the very many stones/boulders.

Similar sediments are recorded along both transects. The sediment appears to be lacustrine, with Units A and B separated by a consistently observed sharp boundary, although both units are internally unstratified. Unit B is generally less organic than the overlying Unit A. The organic content of the sediments is assumed to be derived from contemporary lacustrine biological activity.
