Just some facts:

1. There is a large drainage pond adjacent to the museum.

C. The sinkhole caved in about a week and a half after some sustained low single digit temperatures (0-5 degrees).

I don't know where the drain lines for the pond run.

Here is a GooglEarth snip:

The asterisk marks what I think is the approximate location of the sinkhole inside the dome. It's either where I marked it, or, on the opposite side of the red spire.
