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 a satellite image of the area.

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).

The three specimens recovered from Mount Dewitt are given in the listing below.

Acknowledgments; Nelia Dunbar, Richard Esser, and Bill McIntosh contributed the two Mount Dewitt meteorite specimens to the Antarctic meteorite collection.
