NATURAL BRIDGE, Va. (AP) — -

An emergency official says two Washington & Lee University students were chilly but uninjured after they became lost while hiking and spent the night in the James River Face Wilderness.

Rockbridge County Emergency Management coordinator Robert Foresman tells The Roanoke Times (http://bit.ly/1nsrs3L ) that searchers reached the students around 4:15 a.m. Thursday at Devil's Marbleyard.

Foresman says the students were among four who were hiking at Devil's Marbleyard on Wednesday evening when they became lost. The other two students were quickly found.

He says one student rescued Thursday was wearing a T-shirt and shorts. Temperatures dropped to around 28 degrees Wednesday night.

One firefighter twisted a knee during the search. Another was taken to a hospital after feeling ill.

Devil's Marbleyard is an inclined rock field of boulders.
