ANTARCTIC METEORITE LOCATION AND MAPPING PROJECT (AMLAMP)
EXPLANATORY TEXT

During the 1994-95 field season a two person party was airlifted to the Lonewolf Nunataks (81º20'S 152º50' E) for reconnaissance of the extensive icefields surrounding the isolated nunataks at the southwestern head of the Byrd Glacier. The nunataks are generally aligned SW-NE and form a local topographic high with active icestreams to the north and south. Ice sweeps off the polar plateau grazing by the nunataks on the north, with less active ice flow to the south and over the escarpment. LON40-Figure 1 (19 KB JPEG) is an enlarged portion of a satellite image of the Lonewolf Nunataks. Ice in close proximity to the nunataks appears to be moving relatively slowly, but given the directions of ice flow in the area there are few places where non-local ice has effectively stagnated, therefore no significant concentration of meteorites was discovered.

The period January 20-25, 1995 was spent exploring the area. A total of 11 meteorite specimens were recovered. LON40-Table 1 gives a tabulation of meteorite types of the Lonewolf Nunataks collection.

Meteorite positions were obtained using a handheld GPS receiver in point positioning mode. Generally, each meteorite position is the average of around 100 fixes with Selective Availability on. The locations of the meteorites from the Lonewolf Nunataks are shown on LON40-Figure 2 (90 KB JPEG), which is a scanned portion of the area from the U.S.G.S. Wilhoite Nunataks (1:250000) quadrangle.

Acknowledgments; Ann Hawthorne and John Schutt conducted the meteorite reconnaissance searches. Henry Perk and his aircrew of Kenn-Borek Air, Ltd. piloted the Twin Otter aircraft that put the team into the field. Their contributions are appreciated.
