Russell West Glacier (63°40′S 58°50′W / 63.667°S 58.833°W / -63.667; -58.833 (Russell West Glacier)) is a glacier, 11 nautical miles (20 km; 13 mi) long and 4 nautical miles (7.4 km; 4.6 mi) wide, which lies immediately north of Detroit Plateau and flows from Mount Canicula westward into Bone Bay, on the north side of Trinity Peninsula. This glacier together with Russell East Glacier, which flows eastward into Prince Gustav Channel on the south side of Trinity Peninsula, form a through glacier across the north part of Antarctic Peninsula.[1]

Location

Russell West Glacier flows west into the northwest shore of the western end of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. Its mouth is in Bone Bay on the Bransfield Strait, northeast of Charcot Bay, east of the Orléans Strait, south of Astrolabe Island and southwest of Lafond Bay. It is bounded to the southwest by the Gavin Ice Piedmont. The head of the glacier is between Allen Knoll and Sirius Knoll. At its mouth it passes Wimple Dome to the north.[2][3]

Mapping and name

Russell West Glacier was first surveyed in 1946 by the Falkland Islands Dependencies Survey (FIDS). It was named by the UK Antarctic Place-Names Committee (UK-APC) for Victor Ian Russell, surveyor and leader of the FIDS base at Hope Bay in 1946.[1] Russell was head of the Hope Bay station in 1946 and 1947. In April 1946 Russell led a party of four that, despite gales and snow, found a route across the northern Antarctic Peninsula via what is now called Russell East Glacier. In July and August 1946 Russel reached the west coast via what is now called Russell West Glacier.[4]

Glaciology

Russell West Glacier is in the moist climatic region of the west coast of Trinity Peninsula. In this area rime ice is deposited in huge masses on the northwest faces of nunataks, and these occasionally break off and join the glacier ice below the nunatak. In the late 1950s an ice block measuring 20 metres (66 ft) by 4 by 4 metres (13 by 13 ft) was found below a ridge on Mount Canicula that faces northwest.[5] (Mount Canicula stands on the divide separating Russell East Glacier and Russell West Glacier.[6]) The velocity of the glacier measured at its maximum ice thickness increased by 73% between 1993 and 2014.[7]

Surmounting Russell West Glacier to the north. Named after the settlement of Chelopech in Western Bulgaria.[14]

Zlatolist Hill

63°43′32″S 58°47′00″W / 63.72556°S 58.78333°W / -63.72556; -58.78333 An ice-covered hill rising to 924 metres (3,031 ft).[15] Situated in the north foothills of Detroit Plateau, 5.03 kilometres (3.13 mi) west-northwest of Mount Schuyler, 7.09 kilometres (4.41 mi) northeast of Aureole Hills, 7.2 kilometres (4.5 mi) east of Tinsel Dome. Surmounting Russell West Glacier to the north. Named after the settlement of Zlatolist in Southwestern Bulgaria.[16]

Tinsel Dome

REMA Explorer
The Reference Elevation Model of Antarctica (REMA) gives ice surface measurements of most of the continent. When a feature is ice-covered, the ice surface will differ from the underlying rock surface and will change over time. To see ice surface contours and elevation of a feature as of the last REMA update,
  • Open the Antarctic REMA Explorer
  • Enter the feature's coordinates in the box at the top left that says "Find address or place", then press enter
    The coordinates should be in DMS format, e.g. 65°05'03"S 64°01'02"W. If you only have degrees and minutes, you may not be able to locate the feature.
  • Hover over the icons at the left of the screen
  • Find "Hillshade" and click on that
    In the bottom right of the screen, set "Shading Factor" to 0 to get a clearer image
  • Find "Contour" and click on that
    In the "Contour properties" box, select Contour Interval = 1m
    You can zoom in and out to see the ice surface contours of the feature and nearby features
  • Find "Identify" and click on that
    Click the point where the contour lines seem to indicate the top of the feature
    The "Identify" box will appear to the top left. The Orthometric height is the elevation of the ice surface of the feature at this point.
