Alaska's economy fueled by more than just oil
The North Slope oil fields remain a cornerstone of the economy. Prudhoe Bay fields — drilled on subsurface lands owned by the state government — spin off taxes and royalties that fund 80 percent of state government. New fields continue to be added to the original gushers, helping the state maintain the flow of oil through the Trans-Alaska Oil Pipeline at slightly less than a million barrels a day. That's down from the peak of more than 2 million barrels a day in the 1980s.
