The Sagavanirktok River[pronunciation?] or Sag River (Iñupiaq: Saġvaaniqtuuq) is a stream in the North Slope Borough of the U.S. state of Alaska.[1] It is about 180 miles (290 km) long and originates on the north slope of the Brooks Range, flowing north to the Beaufort Sea near Prudhoe Bay. The Trans-Alaska Pipeline System and Dalton Highway roughly parallel it from Atigun Pass to Deadhorse.[5]
