Location

The Finger Ridges are in the northwest of the Cook Mountains, to the east of Butcher Ridge, north of Harvey Peak and west of Henry Mesa. The highest points on the main ridge are about 2,050 metres (6,730 ft).^[1] The individual ridges are 1 to 2 miles (1.6 to 3.2 km) long and project northward from the higher main ridge. They were mapped by the United States Geological Survey from tellurometer surveys and Navy air photos, 1959–63, and named descriptively by the Advisory Committee on Antarctic Names.^[2]

Harper Ridge

79°9′S 156°57′E. A nearly ice-free ridge in Antarctica, 2 nautical miles (4 km) long and rising to over 1,800 metres (5,900 ft). It extends north from the central part of the Finger Ridges, toward Yamagata Ridge. It was named after Doyal A. Harper of the University of Chicago Yerkes Observatory, Williams Bay, Wisconsin, director of the Center for Astrophysical Research in Antarctica at South Pole Station for several years from 1991.^[3]

Seay Peak

79°05′S 157°30′E. Pointed ice-free peak, 1,805 metres (5,922 ft) high, the northeasternmost summit in the Finger Ridges. Mapped by the USGS from tellurometer surveys and Navy air photos, 1959-63. Named by US-ACAN for Benny F. Seay, a member of the U.S. Army aviation support unit for Topo North and Topo South (1961-62) which conducted the tellurometer surveys.^[4]
