I have no idea what this thing is there for. It marks the beginning of
what I think was a depiction of the Miami-Erie Canal. It had very
little water in it, and what there was had slimey algae growing in it.
There were also little metal things that I think marked the locations
of the various locks on the canal. There was a bigger pyramid
thingy at the other end of the mini-canal, but it was surrounded by
slimy algae water and several spiders had taken up residence in it,
so I didn't take a picture of that one.
