The wonderful thing about photography is that now I don't have to imagine it.
I can see it.

Scary as hell...

How is 330 foot deep possible?? The ground has to go somewhere and it's just mindboggling to think about how it happened. Well, maybe not mindboggling, but it does amaze you looking at the pictures.

And I thought we had some big potholes in east Fort Worth.

The rushing water that is 330+ feet under the surface eats away / erodes the dirt from the bottom up. So that eventually, there is nothing under the street, but a few feet of dirt and 325 feet of empty air. Eventually, the surface collapses into the hole.

What I am confused on is that they said it was the result of a busted sewage line. Those aren't buried 330 feet are they? Was this an underground spring? I can see that happening, but the spring would have to get larger to continue driving away the earth upwards, right? Yeah, I should have paid more attention in school.

You know, I was a little curious about the 330 foot deep sewer line myself. Maybe that's just the way foreign countries do it.
