Review of the Geology and Paleontology of the Ellsworth Mountains, Antarctica
U.S. Geological Survey and The National Academies; USGS OF-2007-1047, Short Research Paper 107; doi:10.3133/of2007-1047.srp107 Review of the geology and paleontology of the Ellsworth Mountains, Antarctica G.F. Webers¹ and J.F. Splettstoesser² ¹Department of Geology, Macalester College, St. Paul, MN 55108, USA ([email protected]) ²P.O. Box 515, Waconia, MN 55387, USA ([email protected]) Abstract The geology of the Ellsworth Mountains has become known in detail only within the past 40-45 years, and the wealth of paleontologic information within the past 25 years. The mountains are an anomaly, structurally speaking, occurring at right angles to the Transantarctic Mountains, implying a crustal plate rotation to reach the present location. Paleontologic affinities with other parts of Gondwanaland are evident, with nearly 150 fossil species ranging in age from Early Cambrian to Permian, with the majority from the Heritage Range. Trilobites and mollusks comprise most of the fauna discovered and identified, including many new genera and species. A Glossopteris flora of Permian age provides a comparison with other Gondwana floras of similar age. The quartzitic rocks that form much of the Sentinel Range have been sculpted by glacial erosion into spectacular alpine topography, resulting in eight of the highest peaks in Antarctica.

The island has been formed by four volcanoes, and the largest of these, Mt Erebus, is the world’s southernmost active volcano. Ross Island is extremely important to New Zealand as it is home to Scott Base, New Zealand’s scientific research station in Antarctica. Scott Base was established at the island’s southern point – Hut Point Peninsula – by Edmund Hillary in 1957. Scott Base is run by Antarctica New Zealand, and its main function is to support scientists as they carry out their vital research on the continent over the summer months. New Zealand has a close relationship with the USA’s McMurdo Station, which is located nearby. During the winter months the island is in Research complete 24-hour darkness and temperatures can drop to –36 °C, which makes outside activities extremely dangerous. Ross Island played a significant part in the incredible exploration era of the early 1900s, when famous explorers such as Robert Scott and Ernest Shackleton used the island as a base as they tried to be the first to reach the South Pole. -
