ANTARCTIC METEORITE LOCATION AND MAPPING PROJECT (AMLAMP)
EXPLANATORY TEXT

Mount Dewitt lies at the northwest corner of the Dry Valleys region (77°12'S 159°50'E). To the north, the Mackay Glacier flows eastward past Mount Dewitt. A large amount of bare ice nearly surrounds the nunatak. DEW91-Figure 1 (82 KB JPEG) is a portion of an ASTER satellite image of the area. During the 1976 season several days were spent in searching the bare ice areas around Mt. Dewitt and eastward near Mt. Littlepage. No metoerites were found as a result of those seasrches (Yanai, 197xx).

A field party, studying tephra layers in the ice, traversed much of the ice area around Mount Dewitt during the 1996-97 field season. One specimen was found on bare ice. Another specimen was found on bedrock a short distance below a bare ice slope. During the 2003-2004 season an Italian party recovered another specimen from the area (Russel et al., 2004). During the 2005-2006 field season, an ANSMET field party spent three days searching the ice. No additional meteorites were discovered.

The three specimens recovered from Mount Dewitt are given in the listing below. Their locations are shown on DEW-Figure 1 (82KB JPEG).

Acknowledgments; Nelia Dunbar, Richard Esser, and Bill McIntosh contributed the two Mount Dewitt meteorite specimens to the Antarctic meteorite collection. The 2005-2006 ANSMET field team consisted of Mary Sue Bell, Graciela Matrajt, John Schutt, and Mike Wyatt.
