Ramsey Glacier (84°24′S 179°20′E / 84.400°S 179.333°E / -84.400; 179.333) is a glacier about 45 nautical miles (83 km; 52 mi) long in Antarctica. It originates in the Bush Mountains near the edge of the polar plateau and flows north through the Queen Maud Mountains of Antarctica to the Ross Ice Shelf eastward of Den Hartog Peak.

Early exploration

The Ramsey Glacier was discovered by the United States Antarctic Service (USAS) on Flight C of February 29 – March 1, 1940. It was named by the Advisory Committee on Antarctic Names (US-ACAN), on the recommendation of Rear Admiral Richard E. Byrd, for Admiral DeWitt Clinton Ramsey, United States Navy, Vice Chief of Naval Operations during U.S. Navy Operation Highjump, 1946–47.[1]

Course

The Ramsey Glacier originates in the Bush Mountains below McIntyre Promontory. It flows northwest, then north past Fulgham Ridge, where it is joined from the left (west) by Bowin Glacier. It continues north between Reid Spur to the east and Sullivan Ridge to the west. Muck Glacier joins from the west after Sullivan Ridge. Muck Glacier is fed from the northwest by Shanklin Glacier. Ramsey Glacier continues north through the Queen Maud Mountains, and receives Millington Glacier from the west before entering the Ross Ice Shelf.[2] It is joined from the right (east) by Erickson Glacier at its mouth.[3]

Named by US-ACAN for Cdr. J.L. Erickson, USN, commanding officer of the USS Staten Island during USN OpDFrz 1965.[8]

Features

The head of the glacier in the Bush Mountains forms between the Fulgham Ridge and McIntyre Promontory. To the northeast are Layman Peak, Mount Bellows and the Reid Spur, which runs along the east side of the Ramsey Glacier. The Sullivan Ridge, terminating in the Four Ramps, runs along the west side of the Ramsey Glacier to the south of the confluence with the Muck Glacier.[2]
