This name originates from United Kingdom. It is part of the Gazetteer of the British Antarctic Territory and the SCAR Composite Gazetteer of Antarctica.
Large subglacial ridge beneath Thwaites Glacier in West Antarctica. It is ~50 km long and 10-30 km wide, rising at least 200 m above the surrounding landscape and aligned roughly NE. Its highest point (S 75.8235°, W 106.7526°) has an elevation of -807 m; the ice thickness over this summit is 1560 m. This ridge is a barrier to ice movement and a significant influence on the glacier’s dynamics. It is surrounded by deeper glacier bed in all directions. Deeper bed troughs lie adjacent to each side of the ridge.
Named after the GHOST Project, a component project of the International Thwaites Glacier Collaboration. This project studies the glacier bed, its topography and composition, and its control of present and future ice flow. The project will study this ridge and the glacier’s bed further upstream.
