Yellowstone about to erupt?!!?!?

"A gigantic crack has appeared in the foothills of the Bighorn Mountains in northern Wyoming. This crack isn’t just a few meters wide, mind you: it has opened up a gap 685 meters (2,250 feet) long and 45 meters (150 feet) wide. The locals are somewhat unfortunately nicknaming it the “gash”, as reported by the Huffington Post."
