This sinkhole has such things as telephone poles, oil equipment, and cars in it,plus more. Years ago this town was known for its oil production and also about 3years ago, Rita passed thru the town doing a lot of damage. The town is inLiberty County near Houston. Wondering if the Liberty of Tx. going to sink?Interesting also that there is a salt dome in middle of this sinkhole. This saltdomesucks in the oil in the ground, if I am correct in my understanding. Is Liberty,phone communication, transportation (cars) and oil production just flat out leavingTexas. Lots of things to think about if you read all of the articles.This second link comments that 'Oil drilling in the area, still dotted with working oil derricks, might have weakened the dome and caused it to collapse, 'http://www.foxnews.com/story/0,2933,354699,00.html
For sure the salt of the earth as a whole in Texas has lost it's preservative qualities as Tx. was the buckle of the Bible belt. Things have changed.over the last ten years or so.
