Wow! Take a look at this.
A geologist explains:
“An engineer from Riverton, WY came out to shed a little light on this giant crack in the earth. Apparently, a wet spring lubricated across a cap rock. Then, a small spring on either side caused the bottom to slide out. [The engineer] estimated 15 to 20 million yards of movement. By range finder, an estimate is 750 yards long and about 50 yards wide.”
Better watch out for the Pumas (@ about 2:00)
