Lillie Glacier Tongue
Location
Ob' Bay is on the Pacific Ocean to the east of the Explorers Range of the Bowers Mountains. It is northwest of the Anare Mountains The bay stretches between Lunik Point below Mount Dergach in the west and Cape Williams in the east. Astapenko Glacier enters the bay to the south of Mount Dergach, and is joined at its point of entry by Chugunov Glacier and Astakhov Glacier to the east. Further east, past Platypus Ridge, Lillie Glacier enters the bay, with Lillie Glacier Tongue extending into the bay. The Sputnik Islands are in the entrance to the bay.
Sailing Directions for Antarctica (1943) says "Lillie Glacier Tongue extends northward from snow-covered rounded hills between Cape Cheetham and Williams Head for a distance of about 20 miles, and is about 125 feet (38.1 m.) high. A sounding of 134 fathoms (245.1 m.) has been plotted about 4 miles northward of the Tongue. Many grounded icebergs and unbroken fast ice fringe the shore, and a strong northwestward current sets along the coast."

Named features, from west to east, include:
Barber Glacier
70°26′S 162°45′E / 70.433°S 162.750°E. A glacier rising just east of Mount Bruce in the Bowers Mountains and flowing north to the coast between Stuhlinger Ice Piedmont and Rosenau Head. Mapped by USGS from surveys and United States Navy air photos, 1960-65. Named by US-ACAN for Capt. Don W. Barber, CE, USA, construction and equipment officer, U.S. Naval Support Force, Antarctica, 1967 and 1968.
Lunik Point
70°32′S 163°06′E / 70.533°S 163.100°E. An ice-covered coastal point, lying 3 nautical miles (5.6 km; 3.5 mi) northeast of Mount Dergach on the west side of Ob' Bay. Photographed and plotted by the Soviet Antarctic Expedition, 1958, and named after the first Soviet moon module (called "Lunik").
Mount Dergach
70°36′S 163°01′E / 70.600°S 163.017°E. A flat-topped, ice-covered mountain located just west of Ob' Bay and south of Lunik Point. Photographed from the air by United States Navy Operation Highjump, 1946-47. Surveyed by the Soviet Antarctic Expedition in 1958 and named after meteorologist A.P. Dergach, a member of the Soviet Antarctic Expedition, 1959-61, who perished in a fire at Mirny Station on August 3, 1960.
Astapenko Glacier
70°40′S 163°00′E / 70.667°S 163.000°E. Glacier, 11 nautical miles (20 km; 13 mi) long, draining the north and northeast slopes of Stanwix Peak in the Bowers Mountains and flowing ENE to Ob' Bay. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960-62. Named by United States Advisory Committee on Antarctic Names (US-ACAN) for Pavel D. Astapenko, Soviet IGY observer, a Weather Central meteorologist at Little America V in 1958.
Chugunov Glacier
70°43′S 163°09′E / 70.717°S 163.150°E. Glacier about 15 nautical miles (28 km; 17 mi) long located just north of Astakhov Glacier in the Bowers Mountains. It is one of several glaciers which drain the east slopes of the Explorers Range and flow to Ob' Bay. Plotted from photographs taken by the Soviet Antarctic Expedition in 1958. Named for N.A. Chugunov, Soviet aerologist who died while taking part in this expedition.
Astakhov Glacier
70°45′S 163°21′E / 70.750°S 163.350°E. The glacier next south of Chugunov Glacier in the Explorers Range, Bowers Mountains. It flows northeast from Mount Hager and enters Ob' Bay just west of Platypus Ridge. Mapped by USGS from surveys and U.S. Navy air photos, 1960-65. Named by US-ACAN for Petr Astakhov, Soviet exchange scientist at the U.S. South Pole Station in 1967.
Platypus Ridge
70°42′S 163°43′E / 70.700°S 163.717°E. Large ice-covered ridge bordering the west side of the mouth of Lillie Glacier. It extends northeast from Bowers Mountains to the head of Ob' Bay. Its position was fixed by S.L. Kirkby, surveyor with Australian National Antarctic Research Expedition (ANARE) (Thala Dan) in Feb. 1962. Named by ANARE after this monotreme mammal, native only to Australia.

Lillie Glacier Tongue
70°34′S 163°48′E / 70.567°S 163.800°E. The prominent seaward extension of the Lillie Glacier into Ob' Bay. Discovered by the British Antarctic Expedition, 1910-13, when the Terra Nova explored westward of Cape North in February 1911. Named by British Antarctic Expedition for Denis G. Lillie, biologist on the Terra Nova.
Sputnik Islands
70°22′S 163°22′E / 70.367°S 163.367°E. Two ice-covered islands, one much larger than the other, located between Cape Cheetham and Cape Williams in the entrance to Ob' Bay. The islands were photographed from the air by United States Navy Operation Highjump, 1946-47. Surveyed by the Soviet Antarctic Expedition, 1958, and named after Sputnik 1, the first Soviet artificial earth satellite.
