Location

The Barton Mountains lie to the south of the point where the

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

. 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.

Features

Mount Usher

. A distinctive mountain overlooking the south side of Keltic Glacier about 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

. An ice-free peak, high, at the north end of the ridge forming the east side of Leigh Hunt Glacier. Named by the

(1901-04).

Mount Clarke

. A mountain, high, located 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

. A peak, high, standing at the northeast end of a ridge running 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

. A mountain, high, standing 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

. Narrow rock ridge, 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.
