56 Sturgeon Bay Ship Canal North Pierhead (WI 31)

latitude 44° 47' 31.3" N
longitude 87° 18' 33.8" W

For some reason (probably a need to load supplies), there's a Pier right by the canal.  This light illuminates the Pier.  The building also contains a fog horn, so it is larger than just the light requires.

Note carefully the height of the catwalk.  During heavy storms, this area can get very wet.
