State police and local fire officials are investigating the cause of a fire that destroyed a large structure early Sunday morning in Penn Forest township.

The fire was first reported at 2:30 a.m. at 118 Smith Road just west of Route 903.

When firefighters from Penn Forest and Franklin townships as well as Albrightsville, Lake Harmony and Lansford arrived on scene they found the large wood frame structure fully involved in flames.

Fire crews made a gallant effort in keeping the flames from destroying the home it was attached to.
