If you enlarge the photo, you can vaguely see the outline of the Birmingham Bridge as it crosses the Little Juniata to what used to be called "Irish Flats" a community that was wiped out in the 1936 flood, with only two buildings surviving.  These can be seen in the photo.  You can read more about "Irish Flats" HERE

In my youth after hearing apocryphal stories about the "Flats", I ventured over and did a little exploring.  The only evidence I found of any settlement there was an old fashioned fire hydrant, poking up through the weeds in the middle of nowhere.
