A husband, wife and their 9-year-old son were found after spending the night lost in the Allegheny National Forest in northwestern Pennsylvania.

State police say the three weren't injured. Their names weren't released, but police say they're from Corry in nearby Erie County.

Relatives alerted police after the family didn't return from hiking. They were last seen about 2 p.m. Sunday and were located about 1:45 p.m. Monday, though police and forest officials didn't say how they were found.

The forest covers 802 square miles in four counties, Elk, Forest, McKean and Warren.

The National Weather Service says the low temperature overnight was 30 degrees. Temperatures were in the mid-40s Monday afternoon.

The family had been hiking on a trail near the Kinzua Dam off Route 59.
