Fletcher Ice Rise
Encyclopedia
Fletcher Ice Rise or Fletcher Promontory, is a large ice rise
, 100 miles long and 40 miles wide, at the southwest side of Ronne Ice Shelf. The feature is completely ice covered and rises between Rutford Ice Stream
and Carlson Inlet
. The ice rise was observed, photographed and roughly sketched by Lieutenant Ronald F. Carlson, U.S. Navy (USN), in the course of a C-130 aircraft flight of December 14–15, 1961 from McMurdo Sound
to this vicinity and returning. Mapped in detail by U.S. Geological Survey (USGS) from Landsat imagery taken 1973-74. Named by Advisory Committee on Antarctic Names (US-ACAN) for Joseph O. Fletcher, director of the Office of Polar Programs, National Science Foundation
, 1971-74.
Ice rise
An ice rise is a clearly defined elevation of the otherwise totally flat ice shelf, typically dome-shaped and rising 100 to 200 meters above the surrounding ice shelf. An ice rise forms where the ice shelf touches the rocky seabed because of an elevation in the seabed that remains below sea level...

Rutford Ice Stream
Rutford Ice Stream is a major Antarctic ice stream, about 180 miles long and over 15 miles wide, which drains southeastward between the Sentinel Range, Ellsworth Mountains and Fletcher Ice Rise into the southwest part of Ronne Ice Shelf...

Carlson Inlet
Carlson Inlet is an ice-filled inlet, long and wide, lying between Fletcher Ice Rise and Fowler Ice Rise in the southwest part of the Ronne Ice Shelf. It was named by the Advisory Committee on Antarctic Names for Lieutenant Ronald F. Carlson, U.S...

McMurdo Sound
The ice-clogged waters of Antarctica's McMurdo Sound extend about 55 km long and wide. The sound opens into the Ross Sea to the north. The Royal Society Range rises from sea level to 13,205 feet on the western shoreline. The nearby McMurdo Ice Shelf scribes McMurdo Sound's southern boundary...
