Let's take this a little farther on the scary side. Mississippi River is so low that salt water has started backing up into the river. Now you have a sinkhole in LA that is right next to a butane underground storage mine. The mine blows up (which they claim could result in a blast 250 times stronger than Hiroshima, and that could open the river even larger, resulting in the gulf going further up river. Now the Saint Louis tower ( if in fact it is a huge tuning fork ) rings out, and creates an earthquake, and it is as big as the one that caused the Mississippi to run backwords for days, than you will have an image similar to that one map that shows the country split in 2 pieces. Damn, River DOOM!
