The post-Christmas snowmobile adventure of five people became a nightmare after two of them died when they fell into Seeley Lake's frozen ice on Friday night.

The Missoula County Sheriff's Office identified the dead as Derek Flesch, 25, from Pablo and Kurt Starkel, 28, from Belgrade.

The five snowmobilers had set out across the lake shortly after dusk Friday.  They came over Jocko Pass from the other side of the Mission Mountains, spent the day around Seeley Lake, stopped by a pizza restaurant in town for dinner, and then decided to head back across the pass toward home, the Country Sherrif's office explained.

Three of them actually fell into the ice water, but one of the other two who didn't fall managed to belly crawl and pull out a 45-year-old man from the water of the Montana lake, reports NBC News.

Two of the three survivors reached the west shore near the lake's campground and called 911 at 6:45 p.m. on Saturday night, which led to a search dispatched by 911 from Two Bear Air in Flatland County that found the two frozen bodies after three hours of search.

The 45-year-old man was also found wet and hypothermic. He was first stabilized and then airlifted to Providence St. Patrick Hospital in Missoula, according to Paige Pavalone, spokeswoman of the Missoula County Sheriff's Office.

Seeley Lake is a mountainous area 100 miles south of Glacier National Park.
