# Larsen Glacier

The Larsen Glacier (75°6′S 162°28′E﻿ / ﻿75.100°S 162.467°E﻿ / -75.100; 162.467) is a glacier flowing southeast from Reeves Névé, through the Prince Albert Mountains and entering the Ross Sea just south of Mount Crummer in Victoria Land, Antarctica.

## Exploration and naming

The Larsen Glacier was discovered by the South Magnetic Party of Ernest Shackleton's British Antarctic Expedition, 1907–09, who followed its course on their way to the plateau area beyond. They named it Larsen Glacier because it flowed past the foot of Mount Larsen, which was constantly in view as they ascended the course of the glacier.

## Location

The Larsen Glacier forms to the southeast of Reeves Névé between the Reed Nunataks and Tomovick Nunatak. It flows southeast past Widowmaker Pass and Mount Gerlache in the Prince Albert Mountains. It continues past the mouth of Backstairs Passage Glacier and Mount Crummer to the north, and Fleming Head to the south, to enter Relief Inlet in the Terra Nova Bay.

## Features

Features of the glacier and the terrain it flows through include:

### Reed Nunataks

74°49′S 161°58′E﻿ / ﻿74.817°S 161.967°E﻿ / -74.817; 161.967. A cluster of nunataks that form a divide between the upper portions of the Reeves Glacier and Larsen Glacier, 6 nautical miles (11 km; 6.9 mi) west of Hansen Nunatak. Mapped by USGS from surveys and United States Navy aerial photographs, 1956-62. Named by US-ACAN for David Reed, USGS Topographic Engineer at McMurdo Station, 1964-65.

### Tomovick Nunatak

74°59′S 161°51′E﻿ / ﻿74.983°S 161.850°E﻿ / -74.983; 161.850. A nunatak along the southern side of the upper portion of Larsen Glacier, 9 nautical miles (17 km; 10 mi) west of Mount Gerlache. Mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1956-62. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Donald S. Tomovick, United States Navy, utilitiesman at South Pole Station in 1966.

### Mount Gerlache

74°59′S 162°26′E﻿ / ﻿74.983°S 162.433°E﻿ / -74.983; 162.433. A prominent mountain, 980 metres (3,220 ft) high, standing on the northeast side of Larsen Glacier between Widowmaker Pass and Backstairs Passage Glacier. Discovered by the British National Antarctic Expedition, 1901-04, and named for Lieutenant Adrien de Gerlache.

### Backstairs Passage Glacier

75°02′S 162°36′E﻿ / ﻿75.033°S 162.600°E﻿ / -75.033; 162.600. A glacier about 2 nautical miles (3.7 km; 2.3 mi) long, draining east along the north side of Mount Crummer to the Ross Sea. The Magnetic Pole Party, led by T.W. Edgeworth David, of the British Antarctic Expedition, 1907-09, ascended this glacier from the Ross Sea, then continued the ascent via Larsen Glacier to the plateau of Victoria Land. So named by David's party because of the circuitous route to get to Larsen Glacier.

### Fleming Head

75°10′S 162°38′E﻿ / ﻿75.167°S 162.633°E﻿ / -75.167; 162.633. A prominent rock headland on the coast of Victoria Land, marking the south side of the terminus of Larsen Glacier where it enters the Ross Sea. Mapped by USGS from surveys and United States Navy air photos, 1957-62. Named by US-ACAN for John P. Fleming, Senior Chief Construction Electrician, United States Navy, a member of the McMurdo Station winter party, 1962 and 1966.
