ANTARCTIC METEORITE LOCATION AND MAPPING PROJECT (AMLAMP)
EXPLANATORY TEXT

Larkman Nunatak (86º 46' S 179º 20' E) is in the eastern Grosvenor Mountains and is the southernmost nunatak in the Shackelton Glacier drainage. The site consists of a main nunatak with a couple of smaller satellite outcroppings. The main area of blue ice is exposed to the north of the largest nunatak with extensive bare ice areas extending northward to Hayman Nunataks. Superglacial moraines are present in close proximity to the nunatak. LAR66-Figure 1 (129 KB JPEG) is an enlarged portion of the U.S.G.S. 1:2500000 scale Plunket Point map. LAR66-Figure 2 (174 KB JPEG) is an oblique aerial view of the Larkman Nunatak area from the south. The Roberts Massif and Shackleton Glacier are in the distance.

An ANSMET team spent 12 days at the site during the 2004-2005 season. Only two and a half days were spent in reconnaissance searches owing to an extended spell of bad weather. However, the team recovered 79 meteorites in that time. ANSMET returned during the 2006-2007 season for systematic search efforts. Four weeks were spent searching the ice and the moraines around Larkman Nunatak and Hayman Nunatak. A total of 632 specimens were recovered.

LAR66-Table1 gives the types of meteorites found at the Larkman Nunatak icefields from the 2004 and 2006 collections.

Acknowledgments; The 2004-2005 ANSMET team was made up of Cari Corrigan, Yulia Goreva, Dave Mittelfehldt, and John Schutt. The 2006-2007 systematic search team included James Day, Matt Genge, Cliff Leight, Shaun Norman, Don Pettit, Mike Rampey, Linda Welzenbach, and Nicolle Zellner.
