## Name

The Malta Plateau was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) to commemorate the island of Malta in association with the Victory Mountains.[1]

## Geology

The plateau is part of the Melbourne Volcanic Province of the McMurdo Volcanic Group.[2]

## Location

The Malta Plateau is to the south of the Trafalgar Glacier, to the east and north of the Seafarer Glacier and the Mariner Glacier, and to the west of the Borchgrevink Glacier.[3][4] The west of the plateau is drained by Potts Glacier to the south, Olson Glacier and Wilhelm Glacier to the west, Osuga Glacier and Trainer Glacier to the north. Features of the west include Mount Heg, Thomas Peak, Soft Snow Pass, Mount Hancox and Mount Finch.[3]

The east of the plateau is drained by the Line Glacier, Hand Glacier and Behr Glacier, which feed the Borchgrevink Glacier to the west, and by the Gruendler Glacier and Rudolph Glacier to the north, which feed the Trafalgar Glacier. Features of the east include Collins Peak, Mount Burrill and Mount Hussey.[3] Features of the south of the plateau include Mount Philipps, Cuneiform Cliffs, Mount Alberts, Tur Peak and Cape Crossfire.[4]

It is bounded on the west, south and east sides by the Seafarer Glacier, Mariner Glacier and Potts Glacier. The mountain first appears on a 1960 New Zealand map compiled from United States Navy aerial photographs. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1972 for James E.

Mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960-64. Named by the US-ACAN for Francis J. Thomas, biologist at McMurdo Station, 1962-63 and 1964-65.[6]

### Soft Snow Pass

[ ⚑ ] 72°37′S 166°34′E﻿ / ﻿72.617°S 166.567°E﻿ / -72.617; 166.567. A snow pass at about 2,000 metres (6,600 ft) high at the head of Osuga Glacier, a tributary of Trafalgar Glacier. So named by the New Zealand Antarctic Research Programme (NZARP) geological party led by M.G. Laird, 1981-82, from the unusually soft snow encountered in the pass.[7]

### Mount Hancox

[ ⚑ ] 72°38′S 166°59′E﻿ / ﻿72.633°S 166.983°E﻿ / -72.633; 166.983. A prominent mountain 3,245 metres (10,646 ft) high about 6 nautical miles (11 km; 6.9 mi) southeast of Mount Burton, rising above the north margin of Malta Plateau. Named by the Mariner Glacier geology party of NZGSAE, 1966-67, for G.T. Hancox, senior geologist with the party in this area.[8]

### Mount Finch

[ ⚑ ] 72°34′S 167°23′E﻿ / ﻿72.567°S 167.383°E﻿ / -72.567; 167.383. A mountain 2,100 metres (6,900 ft) high standing at the west side of the mouth of Trainer Glacier where the latter enters Trafalgar Glacier. Mapped by USGS from surveys and United States Navy air photos, 1960-64. Named by US-ACAN for Lieutenant Jerry L. Finch, United States Navy, Squadron VX-6 project officer for infrared ice sounding equipment and an aircraft commander in Operation Deep Freeze, 1968.[9]

## Eastern features

### Collins Peak

[ ⚑ ] 72°58′S 167°49′E﻿ / ﻿72.967°S 167.817°E﻿ / -72.967; 167.817. A small but noteworthy peak 1,810 metres (5,940 ft) high at the east side of Malta Plateau, on the end of the ridge overlooking the confluence of the Hand and Line Glaciers. Mapped by USGS from surveys and United States Navy air photos, 1960-64. Named by US-ACAN for Eric J. Collins, biologist at Hallett Station, 1965-66.[10]

### Mount Burrill

[ ⚑ ] 72°50′S 167°29′E﻿ / ﻿72.833°S 167.483°E﻿ / -72.833; 167.483. A mountain 2,310 metres (7,580 ft) high on the east edge of Malta Plateau, situated 4 nautical miles (7.4 km; 4.6 mi) south of Mount Hussey at the head of Hand Glacier. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for Doctor Meredith F. Burrill, Executive Secretary of the United States Board on Geographic Names, 1943-73. His leadership in the development of Antarctic names policy and principles has been instrumental in establishing greater international uniformity in the geographic nomenclature of the continent.[11]
