The Jaeger Table (82°36′S 52°30′W / 82.600°S 52.500°W / -82.600; -52.500 (Jaeger Table)) is the ice-covered summit plateau of Dufek Massif, in the Pensacola Mountains of Antarctica, rising to 2,030 metres (6,660 ft) at Worcester Summit.[1]

Mapping and name

edit

The plateau was mapped by the United States Geological Survey (USGS) in 1968 from ground surveys and United States Navy aerial photographs taken 1964. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN), at the suggestion of USGS geologist Arthur B. Ford, after Commander James W. Jaeger, United States Navy, pilot of the Squadron VXE-6 Lockheed C-130 Hercules aircraft that landed the USGS field party in the area in the 1976–77 season.[1]

Location

edit
 

The Jaeger Table is east of Neuburg Peak in the Dufek Massif and west of Davis Valley. The Ford Ice Piedmont is to the north and the Sallee Snowfield is to the south. Features immediately surrounding the plateau include Spear Spur, Kelley Spur, Worcester Summit, Lewis Spur and Carlson Buttress. Features along the escarpment that extends east from the plateau include Frost Spur, Alley Spur, Sapp Rocks and Nutt Bluff.[2]

Features

edit

Spear Spur

edit

82°38′S 52°22′W / 82.633°S 52.367°W / -82.633; -52.367. A rock spur 3 nautical miles (5.6 km; 3.5 mi) east of Clinton Spur on the south side of Dufek Massif. Mapped by USGS from surveys and United States Navy air photos, 1956-66. Named by US-ACAN for Albert Spear, builder, Ellsworth Station winter party, 1957.[3]

Kelley Spur

edit

82°37′S 52°08′W / 82.617°S 52.133°W / -82.617; -52.133. A rock spur 2 nautical miles (3.7 km; 2.3 mi) east of Spear Spur on the south side of Dufek Massif. Mapped by USGS from surveys and United States Navy air photos, 1956-66. Named by US-ACAN for Samuel Kelley, photographer of United States Navy Squadron VX-6 on several Deep Freeze deployments, 1964-70.[4]

Named by US-ACAN in 1979 after Robin Worcester who, with David W. Bennett, comprised the first of the annual USGS satellite surveying teams at the South Pole Station, winter party 1973.[5]

Lewis Spur

edit

82°34′S 52°13′W / 82.567°S 52.217°W / -82.567; -52.217. A rock spur 1.5 nautical miles (2.8 km; 1.7 mi) west of Frost Spur on the north side of Dufek Massif. Mapped by USGS from surveys and United States Navy air photos, 1956-66. Named by US-ACAN for Atles F. Lewis, aviation structural mechanic, Ells worth Station winter party, 1957.[6]

Carlson Buttress

edit

82°35′S 52°27′W / 82.583°S 52.450°W / -82.583; -52.450. A rock buttress to the northwest of Worcester Summit, rising to about 1,800 metres (5,900 ft) high on the north side of Jaeger Table.

The name is suggested by the appearance of the feature caused by weathering along prominent vertical joints in the gabbro rock. Named by Arthur B. Ford, USGS geologist, leader of the USGS Pensacola Mountains survey party, 1978-79.[8]

Czamanske Ridge

edit

82°35′S 52°42′W / 82.583°S 52.700°W / -82.583; -52.700. A ridge between Jaeger Table and Welcome Pass. Named by US-ACAN after Gerald K. Czamanske, USGS geologist, a member of the USGS Pensacola Mountains party, 1976-77.[9]
