ANTARCTIC METEORITE LOCATION AND MAPPING PROJECT (AMLAMP)
EXPLANATORY TEXT


GROSVENOR MOUNTAINS INTRODUCTION

The Grosvenor Mountains (85º40'S 175º00'E) lie at the southeast of the Beardmore Glacier drainage system. The Otway Massif is the largest nunatak in the area, poised at the junction of the Mill Glacier and the Mill Stream Glacier, both large tributaries to the Beardmore Glacier. Other widely separated, relatively small groups of nunataks are present to the southeast. GRO-Figure 1 (85 KB JPEG) is a portion of the 1:250000 scale Plunket Point quadrangle showing the Grosvenor Mountains area. Bare ice areas are present around many of the nunataks. Many of these have produced significant numbers of meteorite specimens.

An ANSMET team conducted reconnaissance searches in the Beardmore Region during the 1985-1986 field season. GRO-Figure 2 (42K JPEG) (adapted from Cassidy, 1992) shows the route of their traverses in the area. Additional reconnaissance was conducted during the 2003-2004 season. Meteorites were found at a number of localities throughout the Grosvenor Mountains. Several meteorites were found at widely scattered sites in the Otway Massif area including an interesting scatter field. Meteorites have been recovered from isolated ice patches surrounded by crevasses in the middle of the Mill Glacier above the Scott Icefalls. Numerous specimens have been recovered from icefields in the Mt. Cecily-Mt. Raymond and Mt. Bumstead areas as a result of reconnaissance and systematic search efforts in the 1985-86 and 1995-96 field seasons. The Block Peak-Mauger Nunatak-Mt. Block area has produced a numerous specimens, mostly from searches conducted during the 2006-2007 field season.
