Mount Semprebon
Mount Semprebon () is a prominent, partly snow-free peak rising 1 nautical mile (1.9 km) northeast of Mount Barsoum in Martin Hills. The peak was positioned by the U.S. Ellworth-Byrd Traverse Party on December 10, 1958, and named for Louis C. Semprebon, an ionospheric physicist and assistant scientific leader at Ellsworth Station Ellsworth Scientific Station ( es, Estación Científica Ellsworth, or simply ''Estación Ellsworth'' or ''Base Ellsworth'') was a permanent, all year-round originally American, then Argentine Antarctic scientific research station named after Amer ... in 1958.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary ...

Martin Hills
The Martin Hills () are an isolated range of predominantly ice-covered hills, or peaks, in Antarctica, nearly long, lying about south of the Pirrit Hills. The feature was positioned by the U.S. Ellsworth–Byrd Traverse Party on 10 December 1958, and was named by the Advisory Committee on Antarctic Names for Larry R.

Ellsworth Station
Ellsworth Scientific Station ( es, Estación Científica Ellsworth, or simply ''Estación Ellsworth'' or ''Base Ellsworth'') was a permanent, all year-round originally American, then Argentine Antarctic scientific research station named after American polar explorer Lincoln Ellsworth. It was located on Gould Bay, on the Filchner Ice Shelf. It was shut down in 1962 over safety concerns due to it being built on increasingly unstable ice, which produced fast deterioration of its superstructures and endangered both personnel and equipment. History Ellsworth Station was built by United States Navy Seabees under the command of Captain Finn Ronne, with the support of the icebreakers USS ''Staten Island'' and USS ''Wyandot'', captained by Francis Gambacorta. The originally planned site for the station was Cape Adams, but when the terrain proved impractical due to huge ice cliffs, an alternate location on Gould Bay was selected, on the western coast of the Weddell Sea over the Filchner ...
