A level grade separate from the old water line, and not looking like a mill race, makes its way along the Hickory Run. Was this one of the old logging railroads? The far western end of this trail was definitely a spur from the Lehigh Valley Railroad, because USGS maps from 1900 show it...but was this an extension? | Metrotrails | Facebook
