ANCHORAGE — A search is underway in western Alaska for four children ranging in age from 2 to 14 who were reported overdue in returning from a snowmobile ride, but poor weather is hampering the search.

The children should have returned to the community of Nunum Iqua early Sunday afternoon, Alaska state troopers said in a Monday web posting.

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

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

Blizzard conditions are hindering search efforts, troopers said.

Nunum Iqua, formerly known as Sheldon Point, is about 500 miles northwest of Anchorage. The 2000 Census put the population at 187 people.
