This benchmark was recovered by following the 1942 CGS description. The beacon tower is at the top of South Mountain between I-78 and Route 145. It is at the end of Beacon Road in Salisbury Township. This road is a steep, one lane, semi-private road. You shouldn't go up, unless you want to see the beacon up close.
