Victoria Land Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78th parallel south, 78°00'S, and westward from the Ross Sea to the edge of the Ant ...

Exploration and naming

Greenville Valley was explored in 1957 by the New Zealand Northern Survey Party of the
Commonwealth Trans-Antarctic Expedition The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South ...
(CTAE), 1956–58. It was named by them after the USNS ''Greenville Victory'', a freighter in the main American convoy into
McMurdo Sound The McMurdo Sound is a sound in Antarctica, known as the southernmost passable body of water in the world, located approximately from the South Pole. Captain James Clark Ross discovered the sound in February 1841 and named it after Lieutenant ...
in the 1956–57 season.


Features


Scuttle Valley

. A small deglaciated valley with meltwater lakes which lies parallel to and just south of Towle Glacier. The valley comprises the lower elevations at the northeast end of Elkhorn Ridge and is separated from Towle Glacier by a dolerite ridge upon which the flank of Towle Glacier rests above the valley floor. The feature was visited by Victoria University's Antarctic Expeditions (VUWAE), 1976-77, led by Christopher J. Burgess. The name derives from the discovery of a parachute and abandoned airdrop packaging in the vicinity.


Sore Thumb

. A notable rock spire (about high which rises above a crest of Elkhorn Ridge, to the east of Topside Glacier. Though not the highest point on the ridge, the spire stands out "like a sore thumb" and is an excellent reference point. The approved name is a shortened form of "Sore Thumb Stack," which had been suggested by New Zealand geologist Christopher J. Burgess during a visit to the area in the 1976-77 season.


Elkhorn Ridge

. A rugged ridge, long, between Towle and Northwind Glaciers. Mapped by USGS from ground surveys and Navy air photos. Named by US-ACAN in 1964 for the United States NavyS ElkhoRoyal Navy, a tanker in the American convoy into McMurdo Sound, 1961-62.


Topside Glacier

. A cirque glacier, long, descending the south wall of Elkhorn Ridge in Greenville Valley. The name is a nautical approximation of the situation of the glacier. Named by a 1989-90 NZARP field party to the area.


Greenville Hole

. A circular depression, deep, in the center of Greenville Valley. The feature is in diameter, ice free and marks the lowest elevation in Convoy Range. Named in association with Greenville Valley.


Bridge Riegel

. A flat-topped rock ridge on the north side of Greenville Valley, immediately above Greenville Hole. The feature provides a platform that overlooks the entire valley, similar to the bridge of a ship. So named by a 1989-90 NZARP field party.


Voigt Ledge

. A flat-topped ridge that rises to high between the head of Greenville Valley and Merrell Valley. The relatively level upper surface of the ledge is long by wide, tapering in the north. It stands high above the adjoining valleys. Named by Advisory Committee on Antarctic Names (US-ACAN) (2008) after Donald E. Voigt of the Department of Geosciences and Penn State Ice and Climate Exploration Center, Pennsylvania State University, who carried out research in glaciology, geophysics and seismology in diverse parts of Antarctica, including the Transantarctic Mountains, in 12 field seasons 1995-2008.


Merrell Valley

. A long, narrow ice-free valley in the Convoy Range, running north from its head immediately east of Mount Gunn into the Greenville Valley. Mapped in 1957 by the N.Z. Northern Survey Party of the CTAE, 1956-58. Named by them after the USNS ''Private Joseph F. Merrell'', a freighter in the main American convoy into McMurdo Sound in the 1956-57 season.
