Plank Bridge Creek

Plank Bridge Creek begins on a mountain in Spring Brook Township. It flows northwest for several hundred feet before turning northeast. After a few tenths of a mile, it turns north for a few tenths of a mile before turning east-northeast and entering a valley between Pinnacle Hill and another hill. The creek then turns north-northeast for several tenths of a mile before turning west-northwest and flowing alongside Spring Brook to its confluence with Spring Brook.
