Well, that could be it, too. It could be the shadow of the Arch itself. Not sure where it would fall at that time.
I lived there. Hell, I still live in Missouri. That picture is photoshopped. Period. There may very well be 100k people at an Obama rally, but that one picture is so phony that it’s not even laughable.
I-70 runs through there on upper AND lower levels, about 8 lanes across. You can’t even SEE the courthouse from down there at the Arch.
Ridiculous.
That's not the shadow of the arch.
Here's an overhead view of the arch. The red line is the arch, the green line is approx. where the shadow is that runs dircetly across the crowd. There's no way, at any time of the day, can the sun cast the arch's shadow running directly across the crowd as seen in the bottom picture.
