Exploration and naming

edit

Mount Freeman was mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960–64. It was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Elliott R. Freeman, United States Navy Reserve, a helicopter aircraft commander during Operation Deep Freeze, 1968.[1]

Location

edit

Mount Freeman is in the Victory Mountains above the Borchgrevink Glacier to the south. It is at the center of a line of mountains to the north of the Borchgrevink Glacier from which alternating ridges and glaciers extend north to the Tucker Glacier. These include, from west to east, McElroy Ridge, Stafford Glacier, Walker Ridge, Coral Sea Glacier, Mount Freeman, Carter Ridge, Mount Lepanto, Elder Glacier, Piore Ridge, Oread Spur, Bowers Glacier, O'Neal Ridge, Mount Northampton, Purvis Peak, Crater Cirque, Walsh Spur, Baker Glacier, Martin Hill and Whitehall Glacier.[2]

Notes

edit
  1. ^ Alberts (1995) says McElroy Ridge is bounded by the Gruendler Glacier, Trainer Glacier, Trafalgar Glacier and Rudolph Glacier.[3] Judging from the map, this is a description of Hackerman Ridge.[2] Alberts (1995) describes Hackerman Ridge as a large mountainous ridge trending north–south between the Gruendler and Rudolph Glaciers.[4] The map shows McElroy Ridge immediately to the east of Hackerman Ridge, between Rudolf Glacier and Stafford Glacier.[2]
