This 2005 photo shows the new Amundsen-Scott South Pole Station (top right) and the old dome station (now dismantled, bottom left). To meet the challenge of drifting snow, the new station is designed with the profile of a sleek airplane wing. It is elevated and faces into the prevailing near-constant 16 to 24 kph (10 to 15 mph) wind, which flows above and below the station. The fast-moving winds beneath the station effectively help scour the area of snow, thereby greatly reducing the need for manual excavation. However, because some snow buildup is inevitable, the building also sits on 36 uniquely designed hydraulic jack columns that allow the 6,040 sq m (65,000 sq ft) structure to be raised in 25 cm (10 in) increments, thereby effectively adding decades to its building life.
