Narrative

A glacier tongue which is the seaward extension of Thwaites Glacier into the Amundsen Sea. It enters the sea about 100km east of Mount Murphy in Marie Byrd Land. At the time of naming the feature projected approximately 100km from the grounding line, with the Thwaites Iceberg Tongue projecting off at 45° for a further 150km (the Iceberg Tongue no longer exists). As of 2020 the feature has drastically reduced in size, the tongue having a significant calving in 2012 (Iceberg B-22) followed by extensive disintegration.
