The Wisconsin Range (85°45′S 125°00′W) 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 Wisconsin Range was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1959–64. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for the University of Wisconsin–Madison, Madison, Wisconsin, which has sent numerous researchers to Antarctica.[1]
The first air photographs of the Wisconsin Range were taken by United States Navy Taskforce 68 during Operation Highjump in 1946–47. In 1958 an oversnow tractor train drove from Byrd Station in West Antarctica to a temporary station on the Ross Ice Shelf. From there, William E. Long and F. Darling walked south to the Wisconsin Range escarpment and gathered samples of granitic rock from Mount LeSchack. In 1964–65 Gunter Faure and John H. Mercer led a group of geologists from what is now the Byrd Polar Research Center of Ohio State University to study the Wisconsin Range and the Long Hills, using snowmobiles and three United States Army helicopters to access all parts of the area.[2] In 1990–91 a team using a Twin Otter airplane sampled basement rocks in the Wisconsin Range.[3]
The Wisconsin Range is east of the Reedy Glacier and south of the Horlick Ice Stream and the Shimizu Ice Stream. The Wisconsin Plateau is in the southeast of the range. The southeast of the range borders the west of the Wisconsin Plateau and overlooks the Olentangy Glacier. From south to north it includes Polygon Spur, Tillite Spur, Red Spur and Mount Huckaby. The southern massif lies between Olentangy Glacier and Norfolk Glacier both tributaries of the Reedy Glacier. It includes Mount McNaughton, Mount Bolton, Goodwin Peak, Haworth Mesa and Sisco Mesa.[4] The Wisconsin Range covers about 8,600 square kilometres (3,300 sq mi) when it is taken to also include the Watson Escarpment south of the Kansas Glacier, the Quartz Hills, the Caloplaca Hills and the Cleveland Mesa, all in the Queen Maud Mountains to the west of the Reedy Glacier.[2]
The southwest part of the range includes Mount Soyat, Mickler Spur and Mount Sweatt between Norfolk Glacier and Hueneme Glacier, another tributary of Reedy Glacier. It includes Griffith Peak, Mount Frontz and Mount Vito to the north of Hueneme Glacier. The central portion of the range extends from west to east and includes Brinton Nunatak, the Ford Nunataks, Martens Peak, Murtaugh Peak, Mount Miashew, Faure Peak, Walters Peak and Lentz Buttress. The Gierloff Nunataks, McCrilliss Nunatak and Gibbon Nunatak are north of the central portion.[4]
The north of the range is north of the Davisville Glacier, a tributary of the Horlick Ice Stream, and mostly south of the Quonset Glacier, a tributary of the Davisville Glacier that rises in Perkins Canyon. From west to east in includes Saunders Rock, Feeley Peak, Sheets Peak, Moran Buttress, Koopman Peak and Ruseski Buttress. Isolated features to the north of Quonset Glacier include, from west to east, Spiers Nunatak, Garczynski Nunatak, Baker Nunatak, Mount Brecher, Angus Nunatak, Mount LeSchack, Spencer Nunatak and Widich Nunatak.[4]
Portions of the Wisconsin Range are recorded in aerial photography obtained by United States Navy Operation Highjump, 1946–47. The Horlick Mountains, including the Wisconsin Range, were completely surveyed by United States Antarctic Research Program (USARP) parties, and was mapped from United States Navy aerial photographs, 1959–64.[5]
