Prudhoe Bay or Sagavanirktok is a census-designated place (CDP) located in North Slope Borough in the U.S. state of Alaska. As of the 2010 census, the population of the CDP was 2,174 people; however, at any given time several thousand transient workers support the Prudhoe Bay oil field. The airport, lodging, and general store are located at Deadhorse; the rigs and processing facilities are located on scattered gravel pads laid atop the tundra. It is only during winter that the surface is hard enough to support heavy equipment and new construction happens at that time.
