Coordinates: The Desko Mountains are a west-northwest–east-southeast mountain range on Rothschild Island, off northwest Alexander Island. The mountain range spans 20 nautical miles (37 km) from Bates Peak to Overton Peak and rises to about 1,000 metres (3,300 ft) at Enigma Peak, Fournier Ridge.
Other mountains nearby are Goward Peak, Schenck Peak, Morrill Peak and Thuma Peak.
To the east lies Lazarev Bay, a rectangular bay that separates the east side of Rothschild Island from the north-west coast of Alexander Island.
The mountains were seen (in part) from a distance by F. Bellingshausen in 1821, and by Jean-Baptiste Charcot in 1909, but the nature of the feature remained obscure.
The Desko mountain range was photographed from the air by U.S. Navy Operation Highjump and the Ronne Antarctic Research Expedition in 1947. The mountain range was further mapped by air by D. Searle of the Falkland Islands Dependencies Survey in 1960. The mountain range was further mapped by the U.S. Navy in 1966, and with Landsat imagery since 1975.
The island was named by the Advisory Committee on Antarctic Names for Commander Daniel A. Desko, U.S. Navy, Commanding Officer, Squadron VXE-6, Operation Deep Freeze, 1977, and LC-130 aircraft commander, 1976.
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 360 km (224 mi) long and 48 km (30 mi) 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 (4,892 m) constituting the highest point on the continent. Geologically, they are part of the Antarctandes which stretch from the Antarctic Peninsula to Cape Adare on the western shore of the Ross Sea. The Antarctandes form the southernmost arc of the Pacific 'Ring of Fire'. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones.
The Branscomb Glacier is an Antarctic glacier, 11 nautical miles long, flowing west from the north-west side of Vinson Massif into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains. Its upper course receives ice influx from both Goodge Col and Jacobsen Valley, while the tributary Roché Glacier joins Branscomb Glacier just northwest of Príncipe de Asturias Peak.

It was named by the Advisory Committee on Antarctic Names after Commander Robert H. Overton, U.S. Coast Guard, Executive Officer, USCGC Westwind, U.S. Navy Operation Deep Freeze, 1971.
Johnson Spur is a rocky spur located 5.67 miles (9.1 km) south-southeast of Taylor Spur, 8.26 miles (13.3 km) southwest of Batil Spur and 8.65 miles (13.9 km) north-northwest of Long Peak, on the east side of the Sentinel Range in the Ellsworth Mountains of Antarctica. It forms the southeastern extremity of the Doyran Heights, and overlooks Rutford Ice Stream to the east and Obelya Glacier to the west.
Evans Peninsula is an ice-covered peninsula about 30 nautical miles (60 km) long, between Koether Inlet and Cadwalader Inlet in the northeast part of Thurston Island. Cape Braathen is an ice-covered cape at the northwest termination of Evans Peninsula. It was discovered in flights from the USS Burton Island and USS Glacier by personnel of the U.S. Navy Bellingshausen Sea Expedition in February 1960, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Commander Griffith Evans, Jr., commander of the icebreaker Burton Island during this expedition.
Evans Point is an ice-covered point fronting on Peacock Sound, lying 15 nautical miles (28 km) west-northwest of Von der Wall Point on the south side of Thurston Island. The Trice Islands lie just to the west. It was first plotted from air photos taken by U.S. Navy Operation Highjump in December 1946, and was named by the Advisory Committee on Antarctic Names for Richard Evans, an oceanographer on the USS Burton Island in this area during the U.S. Navy Bellingshausen Sea Expedition, February 1960.
Linsley Peninsula is a broad, roughly rectangular ice-covered peninsula which protrudes into the south part of Murphy Inlet, northern Thurston Island, Antarctica, dividing the inlet into two arms at the head. The peninsula was first plotted from air photos taken by U.S. Navy Operation Highjump, 1946–47, and was named by the Advisory Committee on Antarctic Names for Lieutenant Commander Richard G. Linsley, U.S. Navy, a pilot of LC-130 Hercules aircraft who made flights in support of the United States Antarctic Research Program geological party working at Thurston Island in the 1968–69 season.

Balgari Nunatak is the mostly ice-fee rocky ridge extending 800 m in east–west direction and 550 m wide, rising to 200 m on the south side of Bongrain Ice Piedmont in northern Alexander Island, Antarctica. It surmounts Lazarev Bay to the south. The nunatak was visited on 3 January 1988 by the geological survey party of Christo Pimpirev and Borislav Kamenov, and Philip Nell and Peter Marquis. On that occasion, a small rocky offshoot situated 360 m southeast of the nunatak's summit was designated as the site for a future Bulgarian Antarctic base. However, the two prefabricated huts brought for the purpose on board the Soviet Research Ship Mikhail Somov in April 1988 could not be helicoptered ashore due to bad weather, and were erected on Livingston Island instead.
Stryama Peak is the ice-covered peak rising to 1700 m on the west side of Rouen Mountains in northern Alexander Island, Antarctica. It surmounts Rosselin Glacier to the north-northwest. The peak's foothills were visited on 10 January 1988 by the geological survey team of Christo Pimpirev and Borislav Kamenov, and Philip Nell and Peter Marquis.
