Broad Valley (63°32′S 57°55′W / 63.533°S 57.917°W[a]) is a descriptive name for the broad glacier-filled valley on the south side of Laclavere Plateau, Trinity Peninsula, Antarctica. The name was suggested by V.I. Russell of the Falkland Islands Dependencies Survey (FIDS) following his survey in 1946.[1]
Location[edit]
Broad Valley is in Graham Land towards the north of the Trinity Peninsula, which forms the tip of the Antarctic Peninsula. It is south of the Laclavère Plateau, west of Duse Bay, north of Eyrie Bay and east of Cugnot Ice Piedmont and Louis Philippe Plateau, from which it is separated by Windy Gap. Misty Pass leads northwest from the valley to the Cockerell Peninsula. Features and nearby features incude Stepup Col, Cain Nunatak, Abel Nunatak and View Point.[2][3]
Features[edit]
Features from west to east include:
Windy Gap[edit]
63°34′S 58°09′W / 63.567°S 58.150°W. Pass 975 metres (3,199 ft) high high, located at the northeast end of Louis Philippe Plateau. It marks the meeting place of three valleys of Trinity Peninsula, namely Broad Valley leading eastward toward Duse Bay, a valley leading northward to Lafond Bay, and another southward to Prince Gustav Channel. Discovered by the Falkland Islands Dependencies Survey (FIDS) and so named because of the very bad weather experienced in the pass during a survey journey in April 1946.[4]
Yarlovo Nunatak[edit]
63°32′52″S 57°58′17″W / 63.54778°S 57.97139°W. A rocky hill rising to 744 metres (2,441 ft) high on Trinity Peninsula. Situated in the northern foothills of Giovannini (Lobell) Ridge, 4.53 kilometres (2.81 mi) west-northwest of Marten Crag, 6.72 kilometres (4.18 mi) south of Prilep Knoll and 11.48 kilometres (7.13 mi) southwest of Kanitz Nunatak. Surmounting Broad Valley to the north. German-British mapping in 1996. Named after the settlement of Yarlovo in Western Bulgaria.[5]
Marten Crag[edit]
63°33′46″S 57°53′12″W / 63.56278°S 57.88667°W. A rocky peak rising to over 700 metres (2,300 ft) high on Trinity Peninsula. Situated between Stepup Col and the eastern foothills of Giovannini (Lobell) Ridge, 8.2 kilometres (5.1 mi) northwest of McCalman Peak, 7.88 kilometres (4.90 mi) north by east of Kribul Hill, 4.53 kilometres (2.81 mi) east-southeast of Yarlovo Nunatak, 9.58 kilometres (5.95 mi) southwest of Kanitz Nunatak and 3.08 kilometres (1.91 mi) west of Kumata Hill. Surmounting Broad Valley to the north and Cugnot Ice Piedmont to the SE. German-British mapping in 1996. Named after the town of Marten in Northeastern Bulgaria.[6]
Stepup Col[edit]
63°34′S 57°51′W / 63.567°S 57.850°W. A snow-covered north–south running col linking Broad Valley and Cugnot Ice Piedmont, at the east end of Louis Philippe Plateau. The name given by UK Antarctic Place-Names Committee (UK-APC) is descriptive, as 100 feet (30 m) in height is gained when the col is traversed in a northerly direction.[7]
Kumata Hill[edit]
63°33′35″S 57°49′30″W / 63.55972°S 57.82500°W. A partly ice-free hill rising to 614 metres (2,014 ft) high on Trinity Peninsula. Situated east of Stepup Col, 6.9 kilometres (4.3 mi) north-northwest of McCalman Peak, 3.08 kilometres (1.91 mi) east of Marten Crag, 7.88 kilometres (4.90 mi) south-southwest of Kanitz Nunatak and 3.37 kilometres (2.09 mi) west-southwest of Cain Nunatak. Surmounting Broad Valley to the north and Cugnot Ice Piedmont to the S. German-British mapping in 1996. Named after the Kumata locality on Vitosha Mountain in Western Bulgaria.[8]
Cain Nunatak[edit]
63°34′S 57°42′W / 63.567°S 57.700°W. The westernmost of two isolated nunataks on the south side of Broad Valley. The name arose at the time of the FIDS geological survey in 1960-61 and is in association with nearby Abel Nunatak.[9]
Abel Nunatak[edit]
63°33′S 57°41′W / 63.550°S 57.683°W. The easternmost of two isolated nunataks on the south side of Broad Valley. The name arose at the time of the FIDS geological survey in 1960-61 and is in association with nearby Cain Nunatak.[10]
Eyrie Bay[edit]
63°35′S 57°38′W / 63.583°S 57.633°W. A bay, 2.5 nautical miles (4.6 km; 2.9 mi) wide at its mouth and extending 3 nautical miles (5.6 km; 3.5 mi) inland, lying north of Jade Point. So named by UK-APC because of the proximity to Eagle Island.[11]
Notes[edit]
- ^ Alberts 1995 gives the coordindates of Broad Valley as 63°22′S 57°55′W / 63.367°S 57.917°W.[1] This appears to be a typo, putting it 10' to far north
