Dispatches from Antarctica's Dry Valleys
Scientists hunt for clues about Earth's climatic past and possible future in one of the world's most remote landscapes.
In 1903, explorer Robert F. Scott and his team stumbled on an anomaly in the frozen, white expanse that is Antarctica: the Dry Valleys, fields of exposed rock with virtually no visible ice. Since 1986, geologist David Marchant of Boston University has spent nearly every Antarctic summer here, decoding a unique landscape. Journalist Jennifer Berglund, assisting Marchant in the field, kept a diary of her adventure.
