The snowmobiler who ran out of gas in northwestern Wisconsin and survived two nights in extreme cold is recovering at a Duluth hospital, the Duluth News Tribune reports.

Craig Friebe, 52, hadn't been seen since Saturday morning and was reported missing by his wife Sunday morning. An initial search by several agencies found no signs of Friebe.

Tiffany Jenner, a plow operator, found him on the ice of the Nemadji River at about 8:50 a.m. Monday and called 911.

"He looked really tough," Jenner tells WDIO. "He looked severely frozen."

Temperatures plunged to -15 and -20 degrees both nights and officials say it's amazing Friebe was able to survive.

Friebe is being treated for hypothermia and frostbite at the Miller-Dwan Burn Center. He's in intensive care, but in fair condition, his brother Bruce Friebe tells the newspaper.
