Isachsen Mountain is a large mountain rising to 2,750 metres (9,020 ft), [1] standing 4 nautical miles (7 km; 5 mi) southeast of Mount Bergersen in the Sør Rondane Mountains of Antarctica. It was mapped by Norwegian cartographers in 1957 from air photos taken by U.S. Navy Operation Highjump, 1946–47, and named for Major Gunnar Isachsen, the leader with Captain Hjalmar Riiser-Larsen of the Norwegian expedition 1930–31.

Mount Bergersen is a large mountain rising to 2,636 m, standing at the west side of Byrdbreen in the Sor Rondane Mountains. It was mapped by Norwegian cartographers in 1946 from air photos taken by the Lars Christensen Expedition, 1936–37, and named for Ambassador Birger Bergersen, chairman of the Norwegian Whaling Board. It was remapped in 1957 by the Norwegians from air photos taken by USN Operation Highjump, 1946-47.
The Sør Rondane Mountains are a group of mountains about 100 miles long with main peaks rising to 3400 m, between the Queen Fabiola Mountains and Wohlthat Mountains in Queen Maud Land. They were discovered and photographed from the air by members of the Lars Christensen Expedition on February 6, 1937, and named after Rondane, a mountain massif in southern Norway. The mountains were mapped in greater detail in 1957 by Norwegian cartographers working with air photos taken by U.S. Navy Operation Highjump, 1946-47.
Operation Highjump, officially titled The United States Navy Antarctic Developments Program, 1946–1947, was a United States Navy operation organized by Rear Admiral Richard E. Byrd, Jr., USN (Ret), Officer in Charge, Task Force 68, and led by Rear Admiral Richard H. Cruzen, USN, Commanding Officer, Task Force 68. Operation Highjump commenced 26 August 1946 and ended in late February 1947. Task Force 68 included 4,700 men, 13 ships, and 33 aircraft. Operation Highjump's primary mission was to establish the Antarctic research base Little America IV.

The Sverdrup Mountains are a group of mountains about 80 km (50 mi) long, standing just west of the Gjelsvik Mountains in Queen Maud Land, East Antarctica. With its summit at 2,655 metres (8,711 ft), the massive Mount Krüger forms the highest point in the Sverdrup Mountains.
Jutulstraumen Glacier is a large glacier in Queen Maud Land, Antarctica, about 120 nautical miles (220 km) long, draining northward to the Fimbul Ice Shelf between the Kirwan Escarpment, Borg Massif and Ahlmann Ridge on the west and the Sverdrup Mountains on the east. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and air photos by the Norwegian expedition (1958–59) and named Jutulstraumen. More specifically jutulen are troll-like figures from Norwegian folk tales. The ice stream reaches speeds of around 4 metres per day near the coast where it is heavily crevassed.
The Jutulpløgsla Crevasses form a crevasse field halfway up Jutulstraumen Glacier, about 8 nautical miles (15 km) southeast of Nashornet Mountain, in Queen Maud Land, Antarctica. They were mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–52) and from air photos by the Norwegian expedition (1958–59) and named Jutulpløgsla.

The United States 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 has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.
The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
