Geology
Geological setting:
Recent moraine and tills have been deposited due to ice separation in two directions in the direction of the Scott Glacier and the valley head; the tills are forming through recent and ongoing ice ablation; the landscape is mobile with kettle holes developing, being infilled with sliding debris and forming inverted sediment cones; soils are moist in the vicinity of the kettle holes and water flows
Patterned ground:
Polygons up to 4m with cracks snow filled
Surface weathering or surface features:
Surface boulders unweathered and subangular to subrounded
Soil
Soil parent material:
Recent bouldery till from predominantly granitic overlying stagnant ice
