Wisconsin Range

The Wisconsin Range (

85°45′S 125°00′W / 85.750°S 125.000°W / -85.750; -125.000) is a major mountain range of the Horlick Mountains in Antarctica, comprising the Wisconsin Plateau and numerous glaciers, ridges and peaks bounded by the Reedy Glacier, Shimizu Ice Stream, Horlick Ice Stream and the interior ice plateau.^[1]

The range was mapped by the USGS from surveys and U.S. Navy air photos, 1959–64. Named by US-ACAN for the University of Wisconsin–Madison, Madison, Wisconsin, which has sent numerous researchers to Antarctica.^[1]

Most of the upland surface area of the range is the Wisconsin Plateau (

85°48′S 125°24′W / 85.800°S 125.400°W / -85.800; -125.400), a large ice-capped plain with general elevations above 2,800 metres (9,186 ft). To the east and southeast, the plateau descends gradually and with only minor ice escarpments to merge with the interior ice plateau; to the north and west, the plateau displays abrupt escarpments and cliffs of over 1,000 metres. Mapped by USGS from surveys and U.S. Navy air photos, 1960–64. Named by US-ACAN in association with the Wisconsin Range.^[2]
