Wisconsin man missing in northwest Alaska

ANCHORAGE, Alaska — Open rivers, thin ice and a lack of snow are holding up a ground search for a 31-year-old Wisconsin man overdue from a trip to northwest Alaska.

Thomas Seibold of Three Lakes was reported overdue Sunday.

Siebold in September traveled to Alaska to hike and explore. Alaska State Troopers say he split from his friends in late September intending to stay at a remote cabin through October.

He was expected to hike 25 miles to the village of Kobuk (COE'-buck) but so far has not appeared.

Seibold is an outdoors and survival instructor. He has camped extensively during winters.

Troopers hope to search along the Ambler River and Ulaneak (oo-LAN'-ee-ack) Creek where Seibold may have built a base camp.

Bad weather has restricted search flights.
