LANCASTER, N.H. (AP) — A hiker who activated an emergency personal locator beacon in New Hampshire’s White Mountains amid brutal weather conditions has been found dead.

The state’s Fish and Game Department says New York City resident Kate Matrosova’s body was found Monday afternoon between Mount Madison and Mount Adams near Star Lake.

Matrosova activated the beacon Sunday. Search and rescue crews couldn’t reach the area overnight because of extreme wind and subzero temperatures. A National Guard crew flew over the area with a helicopter Monday morning but couldn’t see anything because of blowing snow.

A team made up of Fish and Game officers, Mountain Rescue Services members and Androscoggin Valley Search and Rescue members braved 108 mph winds and subzero temperatures to reach the area. They say it appears Matrosova died of exposure to the extreme temperatures.
