Investigators are looking into what caused a big debris fire at a recycling facility in Saint George.  Fire crews were called to the scene at Rocky Mountain Recycling on North Ten-80 East after employees failed to knock the fire down themselves.  Firefighters spent hours on scene yesterday battling the flames but eventually managed to get them under control.  No one was injured by the fire.  Firefighters remained on scene for the rest of the day to make sure the embers didn't reignite the blaze.
