Shedding a little light

I just completed work on a small navigational structure which will be installed at the end of my copper smelter dock. This type of aid to navigation was typical of such structures used throughout the Great Lakes beginning in 1910.

The light at the top was powered by acetylene which was provided by four tanks stored in the small shed at the base of the tower. 

Note the prototypical liberal addition of seagull poop one every possible perching location. Here in the Great Lakes, our nickname for seagulls flying rats!
