That was how "John," one of the SOG's paramilitary officers, unexpectedly found himself peering out the open window of a Soviet-made Mi-17 helicopter that day as it soared over the Anjuman Pass and into the Panjshir Valley, northeast of Kabul. Just ahead on the ground, John spotted a patrol of bearded men in turbans toting AK-47 rifles...
...valley of the dead," declared explorer Robert Falcon Scott after discovering Taylor Valley in 1903, and at first glance it would seem he was right. Yet there is life in the Dry Valleys, albeit life that is primitive in form and exceedingly cryptic. Minuscule roundworms called nematodes and insects known as springtails constitute what biologists jokingly call the "lions and tigers of the soil." The top of the aquatic food chain is occupied by single-cell protozoa that feed on bacteria...
...begin solving this puzzle, scientists working in the Dry Valleys need climate records that extend over a longer period of time, and now it appears they may finally have them. In November, the University of Illinois' Doran and his colleagues retrieved a series of sediment cores from the bottom of three lakes that march up Taylor Valley like Cyclopean footprints: Fryxell, Hoare and Bonney. These cores are layered like the pages of a history book, and the record of geochemical shifts they contain can be used to reconstruct lake levels and stream flow for past centuries. Doran thinks that...

Carrying a pickax and shovel, Boston University geologist David Marchant trudges up a snow-dusted side canyon to Beacon Valley. The ground beneath his feet is as intricately patterned as a quilt, and under its rubble-strewn surface lurks a glacier of venerable age. Marchant believes this glacier has been frozen in place for millions of years--and if he's right, the ice in the glacier holds invaluable clues to an earlier epoch of global warming, one that offers a provocative parallel to the warming expected later in this century...
