Lake Ellsworth
Subglacial Lake Ellsworth is located near the Ellsworth Mountains in West Antarctica at 78.9°S 90.6°W. The lake basin is in the center of the West Antarctic Ice Sheet (WAIS) in the Pine Island Glacier drainage basin, 20 km from the ice divide with the Institute Ice Stream. The lake is approximately...
