A Cantwell woman who burned her snowmachine to survive nearly three nights in wilderness is sure she saw wolves circling her makeshift campsite.

The Fairbanks Daily News-Miner reports 57-year-old Vivian Mayo was severely hypothermic when she was found Tuesday by a search party that included her son Kevin and an Alaska Wildlife Trooper.

She and her husband had traveled to a cabin off the Denali Highway so that he could check his trap line. When he didn't return, Vivian Mayo tried to drive for help but broke down.

Kevin Mayo says rescuers may have trampled any wolf tracks and her vivid description makes him believe his mother saw the predators. But mostly, he's happy his mother was found alive.

His father, Scott Mayo, was found safe a few hours later.
