RHINELANDER - A missing section of a map, a book about the Alaska headwaters, and a diary entry.

Sounds like something out of a spy novel but these items could help locate 31-year-old Thomas Seibold.

He's been missing since early November.

Alaska State Troopers found those things at Seibold's cabin.

Tamarack Song directs the Teaching Drum Outdoor School and knows Seibold.

Song says Seibold should be prepared for any conditions.

At this point, only 25 percent of the "headwaters area", near the Kotzebue River has been searched.

The area is 1,300 square miles.

"We've hired two of the pilots that the troopers had hired themselves to keep searching," Song said.

"We're starting to organize a ground search. We're going to contact a couple of trackers, expert man trackers, and organize a search by snowmobile so we're ready to go as soon as there's enough snow."

Song says the biggest challenges are emotional and psychological.

Even without food, Song thinks he could live for a long time.

"The best case scenario considering the evidence is that he's injured, and that he's taking care of himself," Song said.

"He's just waiting for somebody to fly over and see him. He undoubtedly has some sign, an SOS trampled in the snow or something. We just have to fly over the right spot."

You can help keep the search going by contacting First National Bank in Three Lakes.
