Marble Hills
The Marble Hills () are a group of mainly ice-free hills in West Antarctica. They are located on the west side of Horseshoe Valley, between the Liberty Hills and Independence Hills in the southern part of the Heritage Range, Ellsworth Mountains. The hills were named by the University of Minnesota Ellsworth Mountains Party, 1962–63, because the rocks in these hills are composed of marble Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or Dolomite (mineral), dolomite.

West Antarctica
West Antarctica, or Lesser Antarctica, one of the two major regions of Antarctica, is the part of that continent that lies within the Western Hemisphere, and includes the Antarctic Peninsula. It is separated from East Antarctica by the Transantarctic Mountains and is covered by the West Antarctic Ice Sheet. It lies between the Ross Sea (partly covered by the Ross Ice Shelf), and the Weddell Sea (largely covered by the Filchner-Ronne Ice Shelf). It may be considered a giant peninsula, stretching from the South Pole towards the tip of South America. West Antarctica is largely covered by the Antarctic ice sheet, but there have been signs that climate change is having some effect and that this ice sheet may have started to shrink slightly. Over the past 50 years, the west coast of the Antarctic Peninsula has been - and still is - one of the most rapidly warming parts of the planet, and the coasts of the Peninsula are the only parts of West Antarctica that become (in summer) ice-free ...

Horseshoe Valley (Antarctica)
Horseshoe Valley is a large ice-filled valley in the southern Heritage Range of the Ellsworth Mountains of Antarctica. It is outlined by the semicircular arrangement of the Independence, Marble, Liberty and Enterprise Hills. Approval of the descriptive name was suggested by the University of Minnesota Ellsworth Mountains Party, 1962–63, who reported the name was in wide use by U.S. Navy The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States.

Liberty Hills (Antarctica)
The Liberty Hills () are a line of rugged hills and peaks with bare rock eastern slopes, about long, standing northwest of the Marble Hills and forming part of the west wall of Horseshoe Valley, in the Heritage Range, Ellsworth Mountains, Antarctica. The Liberty Hills were mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1961–66.

Independence Hills
The Independence Hills () are a line of rugged hills and peaks, long, with mainly bare rock eastern slopes. They lie southeast of the Marble Hills and form the southern segment of the west wall of Horseshoe Valley, in the Heritage Range of Antarctica. The Independence Hills were mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1961–66.

Heritage Range
The Heritage Range is a major mountain range, long and wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers. The northern portion of the range was probably first sighted by Lincoln Ellsworth in the course of his trans-Antarctic flight of November 23, 1935. On December 14, 1959, the southern range was seen for the first time in a reconnaissance flight from Byrd Station, made by Edward C. Thiel, J. C. Craddock and E. S. Robinson. The team landed at a glacier on Pipe Peak, in the northwestern part of the range, on December 26.Gerald F.

Ellsworth Mountains
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a long and wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson () constituting the highest point on the continent.Bockheim, J.G., Schaefer, C.E., 2015.

Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or Dolomite (mineral), dolomite. Marble is typically not Foliation (geology), foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for Marble sculpture, sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; Robert S. P. Beekes, R. S. P. Beekes has suggested that a "Pre-Greek origin is probable". This Stem (linguistics), stem is also the ancestor of the English language, English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French language, French , most other European languages (with words like "marmoreal") more closely resemb ...
