Mount Harker

Saint Johns Range () is a crescent-shaped mountain range about long, in Victoria Land, Antarctica.
It is bounded on the north by the Cotton Glacier, Miller Glacier and Debenham Glacier, and on the south by Victoria Valley and the Victoria Upper Glacier and Victoria Lower Glacier.

Name

Saint Johns Range was named by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (CTAE), 1956–58, which surveyed peaks in the range in 1957. Named for St John's College, Cambridge, England, with which several members of the British Antarctic Expedition, 1910–13 were associated during the writing of their scientific reports, and in association with the adjacent Gonville and Caius Range.

Location

Saint Johns Range is bounded to the west by the Victoria Upper Glacier and the Victoria Valley, which runs in a south-southeast direction to Lake Vida.
Below Lake Vida the Victoria Valley turns to an east-northeast direction. It is filled by the Victoria Lower Glacier in its lower end, which flows into the Wilson Piedmont Glacier, lying along the west coast of the Ross Sea.
The Victoria Valley separates Saint Johns Range from the Cruzen Range to the west and the Olympus Range to the south.
The north of the range is separated from the Clare Range by the Cotton Glacier. The Miller Glacier defines the northeast side of the range, flowing into the Debenham Glacier, which defines the north side of the southern arm of the range and terminates in the Wilson Piedmont Glacier.
The Gonville and Caius Range is to the north of the Debenham Glacier.

Northwest features

Features from the northern tip of Saint Johns Range south to Broady Valley are, from north to south: Marchetti Glacier, Gargoyle Turrets, Helicopter Mountains, Mount Mahony, Wheeler Valley, Rutherford Ridge, Mount Rowland, Lobeck Glacier, Kuivinen Ridge, Mount Lewis, Watson Valley, Lanyon Peak and Broady Valley.
