Английская Википедия:Benson Glacier
Шаблон:Short description Шаблон:For Шаблон:Infobox glacier Benson Glacier (Шаблон:Coord) is a glacier about Шаблон:Convert long, draining the east part of Flight Deck Névé and continuing east between Fry Glacier and Mackay Glacier into the north part of Granite Harbour where it forms a floating tongue.Шаблон:Sfn
Exploration and naming
Benson Glacier was mapped in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–1958), and indicated as a somewhat longer glacier including the present Midship Glacier. It was named by the party after Noel Benson, formerly professor of geology at the University of Otago, New Zealand, whose publications include a major contribution to the petrology of Victoria Land.Шаблон:Sfn
Location
The Benson Glacier forms in the northeast end of Alatna Valley in the Convoy Range and flows northeast to the south of Mount Razorback, Dotson Ridge, Flagship Mountain, Mount Davidson (Antarctica) and Mount Nesbelan, which surround Flight Deck Névé. To the south the Benson Glacier flows past Mount Morrison, Mount Brøgger and Black Pudding Peak. Benson Glacier saddles with Gran Glacier, a tributary of Mackay Glacier that flows to the south.Шаблон:Sfn Benson Glacier continues east past Mount Whitcombe, Mount Perseverance and Mount Arrowsmith to the north, and Red Buttress Peak to the south, to flow into Granite Harbour The small Hunt Glacier, which flows from Mount Forde joins the south of the ice tongue of Benson Glacier.Шаблон:Sfn
Midship Glacier divide features
Features of the terrain around the contact between Midship Glacier, Benson Glacier and Cleveland Glacier include:
Jetsam Moraine
Шаблон:Coord. A thin, sinuous medial moraine that arcs smoothly for Шаблон:Convert from a point near Mount Razorback to beyond the far (northeast) side of Black Pudding Peak. Its curved trajectory marks the contact between Benson Glacier ice and that of Midship Glacier. So named by a 1989–1990 NZARP field party from association with Flotsam Moraines and because all supraglacial moraines are "floating" on the glacier ice, and drift similar to flotsam and jetsam.Шаблон:Sfn
Mount Morrison
Шаблон:Coord. A mountain, Шаблон:Convert high, standing between Midship Glacier and the head of Cleveland Glacier. Discovered by the British National Antarctic Expedition (BrNAE) (1901–1904) and named after J. D. Morrison of the Morning, a relief ship to the expedition.Шаблон:Sfn
Dogwatch Saddle
Шаблон:Coord. A snow saddle between Mount Brøgger and Mount Morrison, separating the glacial catchments of the Benson Glacier and Cleveland Glacier. A NZARP field party made a late-night temporary camp on the saddle in January 1990. The name commemorates the midnight hours kept at this location.Шаблон:Sfn
Mount Brøgger
Шаблон:Coord. A mountain, Шаблон:Convert high, which forms part of the north wall of Cleveland Glacier about Шаблон:Convert north of Referring Peak. Charted by the British Antarctic Expedition (1910–1913) which named it for Professor Waldemar C. Brøgger, Norwegian geologist and mineralogist.Шаблон:Sfn
Shipwreck Moraine
Шаблон:Coord. An extensive moraine in a valley beside the Benson Glacier, between Black Pudding Peak and Mount Brøgger. Named by a 1989–1990 NZARP field party (Trevor Chinn) to commemorate an incident at the site. On a descent to the moraine, the motor toboggan and a sledge ran onto blue ice thinly disguised by snow and careened out of control down the slope, tossing gear and personnel overboard as the sledge overturned.Шаблон:Sfn
Black Pudding Peak
Шаблон:Coord. An isolated black mountain located Шаблон:Convert northwest of Mount Brøgger. Named for its squat black appearance by the 1957 New Zealand Northern Survey Party of the CTAE, 1956–1958.Шаблон:Sfn
Névé features
Feature of the Flight Deck Névé, the main source to Benson Glacier, include:
Flight Deck Névé
Шаблон:Coord. An elevated and unusually flat glacier névé, about Шаблон:Convert by Шаблон:Convert, between Flagship Mountain and Mount Razorback. The feature is the primary source of ice to the east-flowing Benson Glacier at Scuppers Icefalls. One of a group of nautical names in Convoy Range applied by NZGB in 1994.Шаблон:Sfn
Dory Nunatak
Шаблон:Coord. An isolated sandstone nunatak, Шаблон:Convert long, rising above the southwest part of Flight Deck Névé, Шаблон:Convert southwest of Dotson Ridge. One of a group of nautical names in Convoy Range. So named by a 1989–1990 NZARP party because the feature appears to be sailing in the midst of the glacier névé like a small boat.Шаблон:Sfn
Dotson Ridge
Шаблон:Coord. A ridgelike nunatak, Шаблон:Convert long, rising to Шаблон:Convert high in the northwest part of Flight Deck Névé. Mapped by the United States Geological Survey (USGS) from ground surveys and Navy air photos. Named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1964 for Morris F. Dotson, electrician at McMurdo Station, 1962.Шаблон:Sfn
Flagship Mountain
Шаблон:Coord. A prominent, conical rock peak, Шаблон:Convert high, surmounting the south part of the large rock mass between Northwind Glacier and Atka Glacier. Named by the New Zealand Northern Survey Party of the CTAE (1956–1958) after the USS Glacier, flagship of the American convoy into McMurdo Sound in the 1956–1957 season, and closely associated with the area in other years.Шаблон:Sfn
Mount Davidson
Шаблон:Coord. A mountain, Шаблон:Convert high, standing at the head of Albrecht Penck Glacier. Discovered by the BrNAE (1901–1904) which named it for a member of the ship's company of the Morning, relief ship to the expedition.Шаблон:Sfn
Mount Nespelen
Шаблон:Coord. A massive mountain, the highest in the coastal ranges between the Mackay Glacier and Fry Glacier, lying on the north side of Benson Glacier, Шаблон:Convert south of Mount Davidson. Named by the New Zealand Northern Survey Party (1956–1957) of the CTAE after the USS Nespelen, one of the vessels of the American convoy to McMurdo Sound that season.Шаблон:Sfn
Scuppers Icefalls
Шаблон:Coord. A prominent line of icefalls, Шаблон:Convert long and nearly Шаблон:Convert high high, between Mount Razorback and Mount Nespelen. The icefalls are the main outflow draining from Flight Deck Névé into Benson Glacier. One of a group of nautical names in Convoy Range, this descriptive name is derived from the drainage of the feature, suggestive of stormwater on a ship's deck draining through scuppers along the rail. Named by a NZARP field party, 1989–1990.Шаблон:Sfn
Lower features
Features of the terrain near the coast include:
Mount Whitcombe
Шаблон:Coord. A large mountain, Шаблон:Convert high, standing just north of Mount Perseverance and west of Mount Arrowsmith at the west side of Evans Piedmont Glacier. Mapped in 1957 by the New Zealand Northern Survey Party of the CTAE, 1956–1958. Named by them for its similarity to the Canterbury, New Zealand, mountain of the same name, and in association with Mount Arrowsmith.Шаблон:Sfn
Mount Perseverance
Шаблон:Coord. The high peak near the south end of the ridge from Mount Whitcombe, overlooking the lower Benson Glacier in Victoria Land. So named because it was the final station occupied by the New Zealand Northern Survey Party of the CTAE (1956-58) during a particularly long day's field work on October 22, 1957.Шаблон:Sfn
Mount Arrowsmith
Шаблон:Coord. A jagged rock peak near Mount Perseverance, Шаблон:Convert along a ridge running northeast from that mountain, and a like distance east of Mount Whitcombe in Victoria Land. Mapped in 1957 by the New Zealand Northern Survey Party of the CTAE (1956–1958). Named by them for its similarity to the Canterbury, New Zealand, mountain of that name, and in association with Mount Whitcombe.Шаблон:Sfn
Mount Forde
Шаблон:Coord. A mountain over Шаблон:Convert high, standing at the head of Hunt Glacier, Шаблон:Convert northwest of Mount Marston. Mapped by the British Antarctic Expedition (1910–1913) and named for Petty Officer Robert Forde, Royal Navy, a member of the expedition's Western Geological Party.Шаблон:Sfn
