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.

  • Mcmurdo Dry Valleys, Southern Victoria Land
    Measure 1 (2004) Annex Management Plan for Antarctic Specially Managed Area No. 2 MCMURDO DRY VALLEYS, SOUTHERN VICTORIA LAND 1. Description of values to be protected and activities to be managed The McMurdo Dry Valleys are characterized as the largest relatively ice-free region in Antarctica with approximately thirty percent of the ground surface largely free of snow and ice. The region encompasses a cold desert ecosystem, whose climate is not only cold and extremely arid (in the Wright Valley the mean annual temperature is –19.8°C and annual precipitation is less than 100 mm water equivalent), but also windy. The landscape of the Area contains glaciers, mountain ranges, ice-covered lakes, meltwater streams, arid patterned soils and permafrost, sand dunes, and interconnected watershed systems. These watersheds have a regional influence on the McMurdo Sound marine ecosystem. The Area’s location, where large-scale seasonal shifts in the water phase occur, is of great importance to the study of climate change. Through shifts in the ice-water balance over time, resulting in contraction and expansion of hydrological features and the accumulations of trace gases in ancient snow, the McMurdo Dry Valley terrain also contains records of past climate change. The extreme climate of the region serves as an important analogue for the conditions of ancient Earth and contemporary Mars, where such climate may have dominated the evolution of landscape and biota. The Area is characterized by unique ecosystems of low biodiversity and reduced food web complexity. However, as the largest ice-free region in Antarctica, the McMurdo Dry Valleys also contain relatively diverse habitats compared with other ice-free areas.

  • Draft ASMA Plan for Dry Valleys
    Measure 18 (2015) Management Plan for Antarctic Specially Managed Area No. 2 MCMURDO DRY VALLEYS, SOUTHERN VICTORIA LAND Introduction The McMurdo Dry Valleys are the largest relatively ice-free region in Antarctica with approximately thirty percent of the ground surface largely free of snow and ice. The region encompasses a cold desert ecosystem, whose climate is not only cold and extremely arid (in the Wright Valley the mean annual temperature is –19.8°C and annual precipitation is less than 100 mm water equivalent), but also windy. The landscape of the Area contains mountain ranges, nunataks, glaciers, ice-free valleys, coastline, ice-covered lakes, ponds, meltwater streams, arid patterned soils and permafrost, sand dunes, and interconnected watershed systems. These watersheds have a regional influence on the McMurdo Sound marine ecosystem. The Area’s location, where large-scale seasonal shifts in the water phase occur, is of great importance to the study of climate change. Through shifts in the ice-water balance over time, resulting in contraction and expansion of hydrological features and the accumulations of trace gases in ancient snow, the McMurdo Dry Valley terrain also contains records of past climate change. The extreme climate of the region serves as an important analogue for the conditions of ancient Earth and contemporary Mars, where such climate may have dominated the evolution of landscape and biota. The Area was jointly proposed by the United States and New Zealand and adopted through Measure 1 (2004). This Management Plan aims to ensure the long-term protection of this unique environment, and to safeguard its values for the conduct of scientific research, education, and more general forms of appreciation.

    George VI of the United Kingdom - Wikipedia, the free encyclopedia 10/6/11 10:20 PM George VI of the United Kingdom From Wikipedia, the free encyclopedia (Redirected from King George VI) George VI (Albert Frederick Arthur George; 14 December 1895 – 6 February 1952) was King of the United Kingdom George VI and the Dominions of the British Commonwealth from 11 December 1936 until his death. He was the last Emperor of India, and the first Head of the Commonwealth. As the second son of King George V, he was not expected to inherit the throne and spent his early life in the shadow of his elder brother, Edward. He served in the Royal Navy and Royal Air Force during World War I, and after the war took on the usual round of public engagements. He married Lady Elizabeth Bowes-Lyon in 1923, and they had two daughters, Elizabeth and Margaret. George's elder brother ascended the throne as Edward VIII on the death of their father in 1936. However, less than a year later Edward revealed his desire to marry the divorced American socialite Wallis Simpson. British Prime Minister Stanley Baldwin advised Edward that for political and Formal portrait, c. 1940–46 religious reasons he could not marry Mrs Simpson and remain king. Edward abdicated in order to marry, and George King of the United Kingdom and the British ascended the throne as the third monarch of the House of Dominions (more...) Windsor. Reign 11 December 1936 – 6 February On the day of his accession, the parliament of the Irish Free 1952 State removed the monarch from its constitution.
