I have no idea if this is in a karst region. But if so, maybe some cavers might check this baby out!

Just put a stand pipe in it and pump it full of concrete. Thats what they do in my neck of the woods............................. yeah.

This was obviously the work of aliens. They are building a labyrinth of hidden chambers in preparation for their upcoming invasion in 2012.

I have seen sinks delvelop like this one over the years here in the Md/Pa area. Not as big though, but close. These rarely open up. It is dangerous to get on the rim of such a thing. A person could get a quick trip to the bottom if the rim edge lets loose. Perhaps an underground Cro-Magnon meeting chamber had collapsed causing the sink.

Let me just stroll right over to the very edge of this reputably unstable sink and broadcast my news report. I think she earned herself the title of "spelunker-journalist"... lol.

Just saw the pics and the video. That's impressive. And a little creepy.

I spent my boyhood in Erick, OK - just down old highway 66 from Sayre. This country is dry and flat. Surface soil is mostly sand, underlain by massive layers of gypsum. I suspect that a solution channel in the gypsum gave way, creating the sinkhole. There is a fairly well-known small cave just outside Erick that is a single solution pathway running about a quarter of a mile. No formations or activity, and it lies very shallow underground, less than 30 feet.

Chances are that the Sayre sinkhole is very similar.
