A group of mountaineers and bikers from Cotabato City witness the beginning of the fire at Mt. Apo, shown in this photo taken at 4:59 pm on Saturday, as they set up tent at a camping site beside Lake Venado. The group says three unidentified mountaineers who slept at the peak may have caused the fire, as they cooked there and left apparently not knowing there was still fire left behind.
