The Havola Escarpment (84°45′S 98°40′W / 84.750°S 98.667°W) is an isolated, snow-covered escarpment about 30 nautical miles (56 km; 35 mi) northwest of the Thiel Mountains in Antarctica. The escarpment is arc shaped, 30 nautical miles (56 km; 35 mi), and faces south.[1]
Discovery and naming[edit]
The Havola Escarpment was observed and mapped by the United States Antarctic Research Program (USARP) Horlick Mountains Traverse party, 1958–59, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Major Antero Havola, United States Army, the leader of the 700 nautical miles (1,300 km; 810 mi) tractor traverse from Byrd Station to South Pole Station from December 8, 1960, to January 11, 1961. On December 25, 1960, the Havola party passed a few miles northward of this escarpment.[1]
Location[edit]
The Havola Escarpment extends in an east-northeast direction from Fowler Knoll at the western end to Davis Promontory at the eastern end. There are no nearby named features.[2]
Fowler Knoll[edit]
84°47′S 99°14′W / 84.783°S 99.233°W. A notable snow-covered knoll, 2,465 metres (8,087 ft) high, with an abrupt south-facing cliff, in the west-central part of the Havola Escarpment. Mapped by the USGS from surveys and United States Navy air photos, 1958-61. Named by US-ACAN for Chief Warrant Officer George W. Fowler, USA, navigator on the 700 nautical mile tractor traverse from Byrd Station to South Pole Station, December 8, 1960 to January 11, 1961. The tractor party, led by Major Antero Havola, passed a few miles northward of this knoll on Dec. 25, 1960.[3]
Davis Promontory[edit]
84°41′S 96°30′W / 84.683°S 96.500°W. A low promontory, completely snow covered, near the northeast end of Havola Escarpment. This promontory which faces southward was occupied by the USARP Horlick Mountains Traverse party, 1960-61. Named by US-ACAN for Walter L. Davis, Chief Construction Mechanic, USN, who wintered over at Ellsworth Station, 1957, and Byrd Station, 1960. Davis was a member of the 11-man tractor party, led by Major Antero Havola, that journeyed from Byrd Station to South Pole Station, 1960-61. On December 25, 1960, the party passed a few miles northward of this promontory.[4]
