Jan 15, 2020 (Therese Pettigrew) - The lake bottom is clay overlain by organic rich sediment in the shallower more sheltered part of the bay. This material is very soft, brown in colour and contains plant and shell fragments. The water at the sample location was 2.3 m deep in 1984. The thickness and lateral extent of sediment was not determined. Similar gelatinous brown sediment with plant and shell fragments underlies part of Helldiver Bay at a depth of 1 to 3 m. When dry the sediment is a fine-grained grey mass with 2 to 3% shell fragments and minor plant material. All parts of it are found to be calcareous when tested with HCl.
Jan 15, 2020 (Therese Pettigrew) - Two samples 84-82 from near Yum Yum Point and 84-84 from Helldiver Bay were submitted for major and trace element analyses: The CaO:MgO ratios are 13.8 making the material an impure (due to its high SiO2 content) dolomitic limestone. Both samples are composed chiefly of calcite with relatively minor amounts of feldspar and quartz.
