This pier was monumented in 1877 and includes the latitude (40° 15' 44') & longitude (76° 52' 56") of its location in Degrees/Minutes/Seconds although the latitude is hard to read due to a horizontal gouge on the face of the stone.
The monument is mentioned in the NGS datasheet for PID #KW0854 (Disk 'L 3' - which is seated in the SE quadrant of the top of the pier) as an Astronomic Station Pier - see text below:
