Short Hike &x28;8&x29;

Large poison ivy vine (Toxicodendron radicans) on an oak tree along the Katellen Trail, Northampton County. The one-mile, blue-blazed Katellen Trail (named for the village of Katellen, where the trail begins) ascends the south slope of Blue Mountain before joining the white-blazed Appalachian Trail at the summit.
