The glacier drains the north, west and southwest slopes of Mount Pontida, and flows into Lazarev Bay north of Mount Holt. It was photographed from the air by Ronne Antarctic Research Expedition in 1947 and was mapped from the photographs by Falkland Islands Dependencies Survey in 1960. Named by Advisory Committee on Antarctic Names for Commander J.H. Wubbold, USCG, commanding officer, USCGC Northwind, U.S. Navy Operation Deepfreeze, 1977.
Neptune Glacier is a glacier on the east coast of Alexander Island, Antarctica, 12 nautical miles (22 km) long and 4 nautical miles (7 km) wide, flowing east into George VI Sound and the George VI Ice Shelf to the south of Triton Point. Although Neptune Glacier is not located within the mountain range Planet Heights, the glaciers name derives from the mountain range along with many other nearby glaciers named after planets of the Solar System. There are also other nearby landforms named in association with these glaciers. The glacier was first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The mouth of the glacier was positioned in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Neptune following a Falkland Islands Dependencies Survey (FIDS) survey in 1949. The head of the glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the FIDS in 1960.

It flows north from the east face of Mount Stephenson into the George VI Ice Shelf that occupies George VI Sound. The glacier was first photographed from the air in 1937 by the British Graham Land Expedition under Rymill. Surveyed in 1948 by the Falkland Islands Dependencies Survey and named for Patrick A. Toynbee, FIDS air pilot at Stonington Island in 1948 and 1949.
Grotto Glacier is a glacier on the east coast of Alexander Island, Antarctica, which flows east into George VI Sound between Belemnite Point and Ablation Point. It is 46 km (29 mi) long, 6 km (4 mi) wide where it emerges from the coastal mountains, and 13 km (8.1 mi) wide at its mouth. It was first photographed from the air on 23 November 1935, by Lincoln Ellsworth and mapped from these photographs by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS). The glacier was so named by the FIDS because a sledge dog was rescued from a grotto-like crevasse in the glacier.
Purcell Snowfield is a snowfield, 15 nautical miles (28 km) wide, lying between the east portion of the Colbert Mountains and the west side of the Douglas Range in the central part of Alexander Island, Antarctica.

The snowfield was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Henry Purcell (1659–1695), English composer.
Palestrina Glacier is a glacier lying in the northern portion of Alexander Island, Antarctica, 11 nautical miles (20 km) long and 8 nautical miles (15 km) wide, flowing west from Nichols Snowfield into Lazarev Bay. The glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Derek J.H. Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Giovanni da Palestrina (1525–1594), Italian composer.
Eros Glacier is a glacier on the east coast of Alexander Island, Antarctica, 7 nautical miles (13 km) long and 2 nautical miles (4 km) wide at its mouth, flowing southeast from the Planet Heights into George VI Sound immediately north of Fossil Bluff. It was probably first seen on November 23, 1935, by Lincoln Ellsworth, who flew directly over the glacier and obtained photos of features north and south of it. The mouth of the glacier was observed and positioned by the British Graham Land Expedition in 1936 and the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. It was named by the UK Antarctic Place-Names Committee after the minor planet Eros in association with nearby Pluto Glacier and Uranus Glacier.

The mountain was probably first observed by Lincoln Ellsworth, who photographed the east side of the Douglas Range from the air on November 23, 1935; its east face was roughly surveyed in 1936 by the British Graham Land Expedition. It was resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named for Ethelred I, Saxon King of England, 865–871. The west face of the mountain was mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Mount Ethelred is the seventh highest peak of Alexander Island, proceeded by Mount Calais.
Mount Ethelwulf is a mainly ice-covered mountain, 2,590 metres (8,500 ft) high, standing between Mount Egbert and Mount Ethelred at the head of Tumble Glacier, in the Douglas Range of northeast Alexander Island, Antarctica. The mountain was probably first observed by Lincoln Ellsworth, who photographed the east side of the Douglas Range from the air on November 23, 1935; its east face was roughly surveyed in 1936 by the British Graham Land Expedition under John Rymill. It was resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named for Ethelwulf, Saxon King of England, 839–858.

Paulus, U.S. Navy, LC-130 aircraft commander, Squadron VXE-6, U.S. Navy Operation Deepfreeze, 1969 and 1970.
Mimas Peak is a sharp conspicuous peak, rising to about 1,000 metres (3,300 ft) west of the head of Saturn Glacier and 9 nautical miles (17 km) west of the Dione Nunataks in the southeast part of Alexander Island, Antarctica. It was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. The peak was sighted from a distance in 1949 by the Falkland Islands Dependencies Survey (FIDS) and roughly positioned. It was named by the UK Antarctic Place-Names Committee for its association with nearby Saturn Glacier, Mimas being one of the satellites of the planet Saturn. The peak and surrounding area were first mapped in detail from air photos taken by the Ronne Antarctic Research Expedition 1947–48, by D. Searle of the FIDS in 1960. Note that some maps incorrectly attach the name to a subsidiary and smaller peak off the east flank of the mountain. The name is actually attached to the highest peak in the Herschel Heights range.
Saturn Glacier is a glacier lying in southeast Alexander Island, Antarctica. The glacier is 15 nautical miles (28 km) long and 6 nautical miles (11 km) wide, flowing southeast into the George VI Ice Shelf of George VI Sound north of Corner Cliffs. Although the glacier is not situated within Planet Heights, its name derives from the nearby mountain range along with many other glaciers named after planets of the Solar System. The nunataks at the head of the glacier are also named after solar system features, for example the Enceladus Nunataks named for a moon of Saturn. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. The glacier was surveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS) and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Saturn, the sixth planet of the Solar System.
