Copper Nunataks
The Copper Nunataks () are a cluster of nunataks across, situated at the head of Wetmore Glacier, west-southwest of Mount Crowell, in southern Palmer Land. The group was mapped by the United States Geological Survey (USGS) from surveys and from U.S. Navy tricamera aerial photography, 1961–67. The name was given by Peter D. Rowley, USGS geologist to this area (1970–71 and 1972–73), who reported that the nunataks contain the largest known copper Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkis ... deposits in Antarctica.

Nunatak
A nunatak (from Inuit language, Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic language, Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial i ...

Wetmore Glacier
Wetmore Glacier is a glacier about 40 miles (64 km) long, flowing southeast between the Rare Range and Latady Mountains into the north part of Gardner Inlet. It was discovered by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Ronne, who named this feature for Alexander Wetmore, Secretary of the Smithsonian Institution, who assisted Ronne in laying out the scientific research program of the expedition.

Mount Crowell
The Latady Mountains are a group of mountains rising west of Gardner Inlet, Orville Coast, between Wetmore Glacier and Ketchum Glacier, in southeastern Palmer Land, Antarctica. They rise to about and include from north to south Mount Aaron, McLaughlin Peak, Mount Robertson, Crain Ridge, Mount Wood, Mount Hyatt, Mount Terrazas, and Schmitt Mesa. The Latady Mountains were seen from the air by the Ronne Antarctic Research Expedition (RARE) on 21 November 1947 and partially surveyed by the Falkland Islands Dependencies Survey and RARE from Stonington Island in December 1947. They were photographed from the air by the U.S. Navy, 1965–67, and mapped from air photographs by the United States Geological Survey The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government.

Palmer Land
Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic Names and the UK Antarctic Place-Names Committee, in which the name Antarctic Peninsula was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69° S. Boundaries In its southern extreme, the Antarctic Peninsula stretches west, with Palmer Land eventually bordering Ellsworth Land along the 80° W line of longitude. Palmer Land is bounded in the south by the ice-covered Carlson Inlet, an arm of the Filchner-Ronne Ice Shelf, which crosses the 80° W line. This is the base of Cetus Hill. This feature is named after Nathaniel Palmer, an American sealer who explored the Antarctic Peninsula area southward of Decep ...

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...
