State officials say a 39-year-old woman and her two sons who got lost and spent a night on New York's highest peak have been treated for cold-related injuries at a hospital.

The Cuomo administration says Ning Cai of Potsdam, New York, and her boys, ages 7 and 11, hiked to the 5,344-foot summit of Mount Marcy in the Adirondacks late Saturday afternoon, then got lost as they headed back down.

Cai called 911 for help and the state Department of Environmental Conservation was alerted. Forest rangers reached the summit around 9:30 p.m., but couldn't find the family.

A state police helicopter spotted them near Marcy's summit around 11 a.m. Sunday. The helicopter first rescued the boys, then went back for their mother.

All three were treated for cold weather-related injuries at Adirondack Medical Center in Lake Placid.
