Members of the U.S. 31st Marine Expeditionary Unit scour the village of Catmon February 22, 2006, for a possible landing area for helicopters. Catmon stands beside the mountain village of Guinsaugon, which was wiped out by a landslide. Rescue workers kept digging on Wednesday for survivors from a deadly Philippine mudslide, but some officials said the time to call of the search was fast approaching as hopes faded of finding anyone alive.
