Massive 'crack in the Earth' opens up suddenly in Wyoming's Bighorn Mountains

A dramatic crack has suddenly formed in the foothills of Wyoming's Bighorn Mountains that measures an impressive 750 yards long and 50 yards wide. It was discovered recently by surprised backcountry hunters who travel frequently to the area in search of game.

First reported by SNS Outfitter & Guides, a hunting company, on their Facebook page, the mammoth chasm appeared over the course of just a couple of weeks. It's an impressive example of just how quickly very large geological events can occur under the right conditions.

“Everyone here is calling it ‘the gash.’ It’s a really incredible sight,” wrote SNS on the group's Facebook page.

“An awesome example of how our earth is not as stable as you might think. Awesome forces at work here to move this much dirt!!” added Randy Becker, one of the hunters to stumble upon “the gash.” Becker shared a number of stunning photographs of the crack to his own Facebook page.

A shot taken from a distance and posted at SNS gives some perspective about just how wide and how deep the crack is:
