Geology
Geological setting:
Ablation till is extensive in the southwest of the basin and shows distinctive moraine loop formations suggesting retreat of ice in two directions; thin bands of till 20-30cm wide are present in the ice and are probably incipient medial moraine; this material is a good example of fresh, unweathered till
light brownish grey to light olive grey (2.5Y 6/2 - 5Y 6/2) silty granule and pebble gravel; loose; rock particles angular to subrounded and unstained,
