Sentinel Range

One of the most spectacular discoveries of the 1963-64 field season was made by the Minnesota party under direction of Campbell Craddock (9) in the Sentinel Range of the Ellsworth Mountains. They submitted a sample of high rank coal accompanied by characteristic elements of the Glossopteris flora at a locality about 600 or 700 miles north of the nearest similar occurrences in the Transantarctic Mountains, intermediate in position between them and the Falkland Islands, where a similar flora (but no coal) has been reported from the work of early Swedish Expeditions.

The Sentinel Range of the Ellsworth Mountains in West Antarctica (Fig. 2.1) includes the Vinson Massif which contains the highest peak in Antarctica at 4,901 m (Stonehouse 2002). The highest peaks of the Transantarctic reach an elevation of 4,528 m in the Queen Alexandra Range along the north side of the Beardmore Glacier (National Geographic Society 1990).
