FAIRBANKS - A fire burning 25 miles southwest of Fairbanks doubled in size in recent days.
The Wood River 1 fire has expanded to more than 60,000 acres, fueled by hot, dry weather.
The Alaska Interagency Coordination Center says smokejumpers have cleared the areas around homes and cabins to protect them from flames.
The agency says the north and northeast edges of the fire have grown faster than other fronts, carrying the fire into pockets of black spruce trees.
Alaska's fire season has been worse than usual this year, with more than 1.5 million acres burned.
