Daisetta, Texas sinkhole

On May 7, 2008, a 20-foot-wide sinkhole in Daisetta, Texas, began swallowing everything in its path and had expanded to 900 feet by the next day with a depth of 260 feet. The former oil town sits on the Hull Salt Dome, a four-mile-in-diameter geologic formation of compacted salt, and geologists speculate that years of storing saltwater waste — a byproduct of oil production — caused the massive pit.
