An open question for geology majors:

Given the depth and size of the hole, and the (very low) value of the property surrounding the hole, what do you do next?

Do you just abandon the "circle" around it, hoping the sides stay "vertical" and don't continue to cave in? I don't realistically see a way to fill it in, given the economy down there.

Downtown FL or just about anywhere in the center of a US city, it'd be filled in, or secured safely.

But down there?

Devil's Millhopper State Park

First think I could think of ;-)

Winter Park Sinkhole

I guess the first real question is whether or not it can actually be stabilized.

They say they can hear water moving. Make a real toilet out of it.
