ANCHORAGE, Alaska – Four children ages 2 to 14 who were reported overdue in returning from a snowmobile ride in western Alaska have been found, rescuers said.

Rescue teams confirmed the children were found Monday – cold, hungry and tired, KTUU-TV reported. Though the rescuers initially said the children were otherwise unharmed, KTVA-TV reported a trooper dispatch later said they are being treated for severe hypothermia.

Blizzard conditions had hampered the search, Alaska state troopers said. The children had been expected to return to the community of Nunum Iqua early Sunday afternoon, troopers said in a web posting Monday.

Troopers identified the children as Christopher Johnson, 14, Frank Johnson, 8, Ethan Camille, 7, and Trey Camille, 2.

Multiple local, state and federal agencies were involved in the search, including helicopters from the Army National Guard and the U.S. Coast Guard.

Nunum Iqua, formerly known as Sheldon Point, is about 500 miles northwest of Anchorage. The 2010 census put the population at 187 people.
