Firefighters work the north flank of the Fontenelle Fire outside Big Piney, Wyoming on Wednesday. Over 800 firefighters are working 15 hour shifts battling the fire that has exceeded 56,000 acres, according to fire information services. Record fire danger and long stretches of the red flag warning days have made it challenging to control. The crews are working and sleeping in close proximity to the fire in an effort to contain it. The blaze, burning in dead and thick stands of timber, started on June 24 and is currently 15 percent contained. Recently firefighting crews from as far away as Alaska have arrived to fight it.
