Light show on a lonesome highway

This intense aurora borealis was captured over the Brooks Range, the stretch of mountains that forms the North Slope of Alaska. Journey hundreds of lonely miles northward via the Dalton Highway and you'll descend into a vast coastal plain before finally reaching the Beaufort Sea coast, where nothing but icy water lies between you and the North Pole.
