ANTARCTIC METEORITE LOCATION AND MAPPING PROJECT (AMLAMP)
EXPLANATORY TEXT

Mt. Bumstead (85º39'S 174º10'E) is more or less centrally located within the nunataks that comprise the Grosvenor Mountains (GRO-Figure 1 - 85 KB JPEG). A moderately large expanse of bare ice is present to the north of Mt. Bumstead. The ice flows westward past the nunatak from off the nearby divide and into the Mill Glacier. GRO60-Figure 1 (63 KB JPEG) is an aerial photo looking southward at most of the ice exposed in the area. GRO60-Figure 2 (41 KB JPEG) is an enlarged portion of the Mt. Bumstead area from the U.S.G.S. 1:250000 scale Plunket Point quadrangle.

The icefield at Mt. Bumstead was briefly visited by a reconnaissance team during the 1985-1986 season (Cassidy 1992). No meteorites were found at that time. During the 1995-1996 season however, a field party spent a few days at Mt. Bumstead. The icefield was systematically searched which resulted in the recovery of 15 meteorite specimens. Abundant terrestrial material, blown out on to the ice from nearby Mt. Bumstead, made searching somewhat more difficult.

GRO60-Table 1 gives a tabulation of the various meteorite types recovered from the icefield at Mt. Bumstead.

Acknowledgments; ANSMET field party members during the 1985-1986 season were William Cassidy, Peter Englert, Twyla Thomas, Carl Thompson. Field members of the 1995-1996 party included Ralph Harvey, Pascal Lee, Anders Meibom, and John Schutt.
