Teams plan another day of searching Saturday for a 60-year-old man missing in Washington's Olympic National Park.

Jim Griffin hasn't been seen since he went for a hike Monday on the Olympic Hot Springs Trail. His friends reported him missing Wednesday night after he failed to show up at a Christmas Eve dinner.

The National Park Service said three searchers spent that night looking for him, and two two-person teams looked for him on Thursday. In the afternoon, they found his day pack 50 feet off the trail, just half a mile from the trailhead.

Searchers from Olympic National Park, Olympic Mountain Rescue and three dog teams found no further sign of him on Friday.

Officials said Griffin frequently takes day hikes to the Olympic Hot Springs.
