On the Web at http://www.asa.org January 2, 2000 Published during the austral summer at McMurdo Station, Antarctica, for the United States Antarctic Program Searching the snows for space rocks By Aaron Spitzer The Antarctic Sun With a glimmer of pride in his eye, researcher Ralph Harvey gently lifts the lid of a wooden box, revealing a fist-sized, fractured black stone. Harvey found the rock earlier this season in Antarctica, but it came from 200 million miles away. The stone is a meteorite, which traveled to Earth from the vast asteroid belt between Mars and Jupiter. And Harvey, a geology professor at Case Western Reserve University in Cleveland, is a meteorite hunter.

The AAC held an Alpine Climbing Camp in Baffin Island in 1979, as described by E. Whalley (63 29), which explored the area of mountains near Ayr Lake some 40km to the W of the Clyde River. The region had not been visited much before and some 30 first ascents were recorded of mountains of around the 1500m mark. Heights were read with 2 aircraft altimeters thought to measure accurately to 3m. Kevin O'Connell (63 70) gives some weather data for Baffin Island, gathered in May 1979, which is presented in the form of pressure and temperature graphs over a 25 day period. This was collected while he was a member ofthe above party-he was also responsible for the height measurements. Other reports on visits to the Eastern Arctic Mountains appear in 63 107-109, and largely deal with other expeditions to Baffin. Montagnes 13 80 has an article by Giles Bordessoule on a solo 700km ski traverse of Spitzbergen, made carrying his gear on a small sledge which he towed behind him. In Montagnes 14 71, he discusses the equipment used on his trip. OJ! Belay 48 33 contains a list of the highest mountains in Antarctica which is reproduced

Antarctica: the Lore and the Profits
Antarctica: The Lore and the Profits PETER D CLARKSON Executive Secretary The Scientific Committee on Antarctic Research (SCAR) Scott Polar Research Institute (Plates I, 2) Antarctica was the great terra australis incognita of the planet for centuries, although the ancient Greeks had postulated its existence to 'balance' the known world in the northern hemisphere. Early explorers who circumnavigated the globe gradually reduced the limit of the hypothetical southern continent as they sailed farther south without sighting land, but it was not until Captain Cook's second voyage (1772-75) in high southern latitudes that Antarctica's isolation and approximate maximum size were confirmed. Cook was rather unlucky in failing to sight the coast of Antarctica because his farthest penetrations south were in areas of extensive pack ice. But it was Cook who inadvertently precipitated the earliest exploration ofthe south polar regions when he reported the abundance of fur seals on South Georgia. Commercial interests drove sealers to exploit the seal stocks and then to search for additional sealing grounds as profits began to fall. This led to new discoveries, although they were often kept secret for proprietary reasons, but the sighting of the Antarctic continent is generally attributed to Thaddeus Bellingshausen. Geographical exploration stimulated other expeditions in the 19th century with the pioneering voyages ofJames Clark Ross, already famous for Arctic exploration, Charles Wilkes, Dumont d'UrviIle and others. However, it must not be forgotten that, in the minds of the sponsors at least, the thirst for knowledge was not entirely divorced from the hope of possible profitable returns from these ventures.

Antarctica 2007,2008
NICK LEWIS Antarctica 2007,2008 s usual, the vast majority of mountaineers visiting Antarctica went to A the Vinson Massif (now commonly referred to as Mount Vinson) and despite very mixed weather, a total of 157 climbed the mountain during the 2007-08 season. This year, Antarctic Logistics & Expeditions (ALE), the logistics operator who run the flights in and out of Vinson Base Camp and provide support on the mountain, developed a different route which climbs the shoulder immediately to the south of the old route which climbed the 'headwall' to the Goodge Col between Vinson and Mount Shinn. The headwall itself had become increas1ngly more serac-ridden and subject to avalanche over the last few years and many people were becoming concerned at the increased risk. Roger Mear, Dave Hahn and others had suggested this route in the 1990s as a quick and safe way of accessing the high plateau but the route saw only infrequent ascents. ALE fixed 1200m of rope up the shoulder in November, and by December 2007 it had become the standard route for the majority of parties. In addition, several rescue caches and a radio repeater were also placed on the mountain by ALE for the benefit of all. These provided crucial support to those climbers caught in vicious storms this season. Notable ascents of the season include Norwegians Ine-Lill Gabrielsen and Rita Glenne who climbed Vinson and then skied to the South Pole from Vinson Base Camp, unsupported, via a new route. Two groups - a Norwegian/Danish female team led by Randi Skaug and an elite Italian military Alpini team led by Ettore Taufer - skied the 200km from the ALE Patriot Hills camp in the Southern Ellsworths to Vinson before making successful ascents.
