Barton Mountains

The Barton Mountains (-85.03333°N, 173°W) are a group of mountains located south of the Commonwealth Range and the Hughes Range and bounded by Keltie Glacier, Brandau Glacier, Leigh Hunt Glacier, and Snakeskin Glacier, in the Queen Maud Mountains.

Exploration and naming
The Barton Mountains were mapped by the United States Geological Survey (USGS) from surveys and from United States Navy aerial photographs, 1958–63. They were named by the Advisory Committee on Antarctic Names (US-ACAN) after Lieutenant Commander Walter H. Barton, U.S. Navy, officer in charge of the Squadron VXE-6 detachment at Beardmore South Camp in the 1985–86 field season. Lieutenant Commander Barton developed, coordinated, and executed the logistical plan for this large and remote camp, which was in operation for 78 days and required over 800 flight hours in support of research in the Beardmore Glacier area.

Location
The Barton Mountains lie to the south of the point where the Brandau Glacier enters the Keltie Glacier from the southwest. They are separated from the Supporters Range to the west by the Snakeskin Glacier. Northern features include Mount Usher, and Hare Peak to the east across Leigh Hunt Glacier. Features of the south of range include Mount Clarke, Graphite Peak and Tricorn Mountain. Falkenhof Glacier forms in the Barton Mountains and runs west into Snakeskin Glacier, which defines the west side of the range. The Lhasa Nunatak is a long ridge running north-south to the west of Snakeskin Glacier.

Mount Usher
-84.95°N, 172.06667°W. A distinctive mountain overlooking the south side of Keltic Glacier about 4 nmi southwest of the mouth of Brandau Glacier. Discovered and named by the British Antarctic Expedition (1907-09). Identification of this feature varied on subsequent maps. The present description follows the H.E. Saunders map of 1961 which has now been generally accepted.

Hare Peak
-84.98333°N, 174.28333°W. An ice-free peak, 2,970 m high, at the north end of the ridge forming the east side of Leigh Hunt Glacier. Named by the New Zealand Geological Survey Antarctic Expedition (NZGSAE) (1961-62) for C.H. Hare, a member of the British National Antarctic Expedition (1901-04).

Mount Clarke
-85.08333°N, 172.3°W. A mountain, 3,210 m high, located 13 nmi due east of Mount Iveagh. The feature rises along the east margin of the Snakeskin Glacier, near the edge of the interior ice plateau. Discovered and named by the Southern Journey Party of the British Antarctic Expedition (1907-09) under Ernest Shackleton.

Graphite Peak
-85.05°N, 172.75°W. A peak, 3,260 m high, standing at the northeast end of a ridge running 3 nmi northeast from Mount Clarke, just south of the head of Falkenhof Glacier. So named by the NZGSAE (1961-62) because of the graphite found on the peak.

Tricorn Mountain
-85.05°N, 173.45°W. A mountain, 3,475 m high, standing 4 nmi east of Graphite Peak, about midway between the heads of Falkenhof and Leigh Hunt Glaciers. Named by the NZGSAE (1961-62) because of its resemblance to an admiral's tricorn hat.

Lhasa Nunatak
-85.11667°N, 171.3°W. Narrow rock ridge, 9 nmi long, trending in a northwest–southeast direction between Snakeskin Glacier and Jensen Glacier, to the east of Supporters Range. So named by the NZGSAE (1961-62) because the central peak resembles a Tibetan monastery perched on top of a hill.
