Helli Listers

I would like to thank everyone that submitted their answers and congratulated John L C for being the Lister to send me the correct answer. He will be receiving a free Harrisonville 245mg meteorite fragment found in 1933 in Cass Co. Missouri.


Question


What is the first ANSMET meteorite to be collected?


Answer

Allan Hills 76001 (ALHA 76001)found in 1976 or 1978 by the ANSMET team.


For those you that would like to read up on the Antartica research trips I was able to find a PDF copy METEORITES,ICE, AND ANTARTICA a personal account by William A. Cassidy

Introduction

The Yamato Mountain Range wraps the ice sheet around its shoulders
like an old man with a shawl. Ice coming from high off the ice
plateau of East Antarctica, arriving from as far away as a subice ridge
600 km to the south, finds this mountain range is the first barrier to
its flow. The ice has piled its substance up against the mountains in
a titanic contest that pits billions of tons of advancing ice against immovable
rock, whose roots extend at least to a depth of 30 km. The
ice is moving because billions of tons of ice are behind it, pushing it
off the continent and into the sea. Ultimately it yields, diverging to
flow around the mountains. On the upstream side the rocks have been
almost completely overwhelmed ? only pink granite peaks protrude
above the ice, which spills down between and around them in tremendous
frozen streams and eddies, lobes, and deeply crevassed icefalls.
The change in elevation of some 1100 m between the high plateau
upstream of the mountains and the lower ice flowing away from the
downstream slopes creates a spectacular view of this giant downward
step in the ice surface. Almost constant howling winds from the interior
blow streamers of ice crystals off the mountain peaks and ?snow
snakes? dance down the slopes in sinuous trains, as if somehow connected
to each other. The scale of the scene is such that people become
mere specks in an awesome, frigid emptiness.
