It is surrounded by snowcapped peaks to the east & west, Bear Glacier to the north, and a long, thin beach to the south, separating the lagoon from the Gulf of Alaska. It is widely accepted that geothermal heat flux (volcanic activity) beneath the West Antarctic ice sheet – and Thwaites Glacier – is a “critical factor” in the active melting for the region.
