Dozens of professional and volunteer searchers have begun a third day of searching for a 29-year-old man believed to be missing in Ohiopyle State Park.
Assistant park manager Stacie Hall said the man's family hasn't heard from him since New Year's Eve. Crews began searching the park after the man's car was found parked there Wednesday.
Crews searched until after dark on Thursday, and picked up the search again about 7 a.m. Friday in frigid temperatures.
Authorities haven't released the man's name because they were still trying to notify other relatives that he is missing.
The park, about 50 miles southeast of Pittsburgh, covers more than 20,000 acres and includes whitewater rapids on the Youghiogheny ) River.
