Location

Trinity Peninsula, Antarctic Peninsula. Louis Philippe Plateau towards the southwest

The Sjögren Glacier is in Graham Land towards the southwest of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. It flows southeast from the Detroit Plateau to enter Prince Gustav Channel opposite Rohss Bay on James Ross Island. It is north of Mount Tucker and Longing Peninsula, and northeast of Larsen Inlet. Mount Hornsby looks over its western side.

Discovery and name

Sjögren Glacier was discovered in 1903 by the Swedish Antarctic Expedition (SwedAE) under Otto Nordenskjold. He named it Hj. Sjögren Fiord after a patron of the expedition. The true nature of the feature was determined by the Falkland Islands Dependencies Survey (FIDS) in 1945.

Northern features

Mureno Peak

64°08′40″S 59°10′15″W. A rocky, mostly ice-free peak rising to 1,100 metres (3,600 ft) high in the north part of Aldomir Ridge. Situated between Sjögren and Boydell Glaciers, 5.18 kilometres (3.22 mi) south-southwest of Lobosh Peak, 16.9 kilometres (10.5 mi) northwest of Mount Wild, 7.15 kilometres (4.44 mi) north-northwest of Vetrovala Peak, 11.94 kilometres (7.42 mi) north of Draka Nunatak, 10.34 kilometres (6.42 mi) northeast of Mount Hornsby and 7.22 kilometres (4.49 mi) southeast of Seydol Crag. British mapping in 1983. Named after the settlement of Mureno in Western Bulgaria.

Aldomir Ridge

64°09′35″S 59°08′10″W. A mostly ice-free ridge on southern Trinity Peninsula bounded by Sjögren Glacier to the west and Boydell Glacier to the east. Extending 14 kilometres (8.7 mi) between Detroit Plateau to the north-northwest and Sjögren Inlet to the south-southeast, 4.2 kilometres (2.6 mi) wide and rising to 1,350 metres (4,430 ft) high at its north extremity. Named after the settlement of Aldomirovtsi in Western Bulgaria.

Boydell Glacier

64°11′S 59°04′W. A glacier about 9 nautical miles (17 km; 10 mi) long, flowing southeast from the Detroit Plateau, Graham Land, and merging on the south side with Sjögren Glacier. Mapped bythe Falkland Islands Dependencies Survey (FIDS) from surveys (1960-61). Named by the UK Antarctic Place-Names Committee (UK-APC) for James Boydell, English inventor of a steam traction engine, the first practical track-laying vehicle (British Patents of 1846 and 1854).

Mount Wild

64°12′S 58°53′W. Sharply defined rock ridge with several summits, the highest 945 metres (3,100 ft) high, standing at the north side of the mouth of Sjogren Glacier. First charted by the FIDS in 1945 and named for Frank Wild.

Central features

Mount Daynes

64°12′12″S 59°06′35″W. Also known as Vetrovala Peak (Bulgarian). Locally prominent peak rising to 936 metres (3,071 ft) high at the south-eastern end of the promontory between Boydell and Sjögren glaciers. Named for Roger Daynes (b.1942), meteorologist and BC at Halley 1971-73. Co-founder, owner and Director of Snowsled Ltd 2000-16, manufacturers of Nansen sledges and pyramid tents for BAS since 1988 and designers and suppliers of polar equipment to many national polar research programmes and expeditions.

Royak Point

64°12′49″S 59°03′36″W. A rocky point on the northwest coast of Sjögren Inlet in southern Trinity Peninsula formed by the southeast extremity of Aldomir Ridge. Situated 2.6 kilometres (1.6 mi) southeast of Vetrovala Peak, 12.2 kilometres (7.6 mi) west of the headland formed by Mount Wild, and 16.25 kilometres (10.10 mi) northwest of the south side of the entrance to Sjögren Inlet. Formed as a result of the retreat of Sjögren Glacier and Boydell Glacier in the first decade of 21st century. Antarctic Digital Database mapping 2012. Named after the settlement of Royak in Northeastern Bulgaria.

Sjögren Inlet

64.2333333°S 59°W / -64.2333333; -59 An inlet exposed following the retreat of Sjögren Glacier, approximately 9 nautical miles (17 km; 10 mi) long running east-southeast from the base of Sjögren Glacier, into Prince Gustav Channel, north of Longing Peninsula. Named by UK Antarctic Place-names Committee (UK-APC) (2006) in association with Sjögren Glacier.

Sjögren Glacier Tongue

64°14′S 58°38′W. A tongue of ice between 5 and 7 nautical miles (9.3 and 13.0 km; 5.8 and 8.1 mi) {{coord|wide, extending 15 nautical miles (28 km; 17 mi) {{coord|from Sjögren Glacier across Prince Gustav Channel toward Persson Island. It was mapped from surveys by tge Falkland Islands Dependencies Survey (FIDS) (1960–61). The glacier tongue was an extension of the flow of Sjögren Glacier from which it took its name. It has disappeared since at least 1994, with its area now covered by the Prince Gustav Channel.

Southern features

Hazarbasanov Ridge

64°13′07″S 59°16′35″W. A mostly ice-free ridge 5.5 kilometres (3.4 mi) long, 2.4 kilometres (1.5 mi) wide and rising to 750 metres (2,460 ft) high on the southwest side of Sjögren Glacier. Situated 4.34 kilometres (2.70 mi) southeast of Mount Hornsby, 6.57 kilometres (4.08 mi) south of Survakari Nunatak, 8.51 kilometres (5.29 mi) west-southwest of Vetrovala Peak. Named after Dobri Hazarbasanov (b. 1960), physician at St. Kliment Ohridski Base during the 1995/96 and subsequent seasons.

Mount Hornsby

64°14′S 59°15′W. A prominent snow-capped mountain on the south side of the middle reaches of Sjögren Glacier. Mapped from surveys by FIDS (1960-61). Named by UK-APC after Richard Hornsby and Sons of Grantham, who designed and constructed several highly successful chain-track vehicles for the British War Office, the first "caterpillar tractors,|1904-10.

Shortcut Col

64°16′S 59°13′W. A wide col rising to over 460 metres (1,510 ft) immediately south of Mount Hornsby. Mapped from surveys by FIDS (1960-61). So named by UK-APC because this col provides a useful shortcut, avoiding the long detour through Longing Gap.

Downham Peak

64°17′S 58°54′W. A rock pyramid at the south side of the mouth of Sjögren Glacier. Mapped from surveys by FIDS (1960-61). Named by UK-APC for Noel Y. Downham, FIDS meteorological assistant at Hope Bay, who assisted in the triangulation of this area in 1961.
