Fault Bluff
Fault Bluff is a high rock bluff located about northeast of Mount Longhurst in the Cook Mountains of Antarctica. The rock bluff was visited in the 1957–58 season by the Darwin Glacier (Antarctica), Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition, 1956–58. They originated the name which presumably refers to a geological fault at the bluff.Stewart, J., 2011. ''Antarctica: An Encyclopedia,'' 2nd ed. Jefferson, North Carolina and London, McFarland & Company, Inc. 1771 pp. Geology Fault Bluff is a paleontologically important outcrop of the Aztec Siltstone that has yielded abundant fossils of Devonian vertebrates, including ''Bothriolepis'' and ''Groenlandaspis'' (armored placoderm fishes) and scales of an extinct lobe-finned fish. The fossils occur either as thin layers of well preserved, concentrated, bone beds or well-sorted, silt-size, ''bone mush''. The bone beds have yielded complete fish spines and bony plates.Long, J., 2001. ''Mountains of Madness: A Sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cook Mountains
The Cook Mountains () is a group of mountains bounded by the Mulock and Darwin glaciers in Antarctica. They are south of the Worcester Range and north of the Darwin Mountains and the Britannia Range. Early exploration and naming Parts of the group were first viewed from the Ross Ice Shelf by the British National Antarctic Expedition (BrNAE) of 1901–04. Additional portions of these mountains were mapped by a New Zealand party of the Commonwealth Trans-Antarctic Expedition (CTAE) of 1956–58, and they were completely mapped by the United States Geological Survey (USGS) from tellurometer surveys and US Navy air photos, 1959–63. Named by the NZ-APC for Captain James Cook. Location The Cook Mountains are bounded by the Darwin Glacier to the south, which separates the range from the Darwin Mountains. The Ross Ice Shelf lies to the east and the Mulock Glacier to the north, which separates it from the Worcester Range. To the west is the Darwin Névé and the Antarctic ice sh ...
