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.

Contrary to some sensational claims swirling about on social media, the crack is not an opening to the underworld or a sign that Yellowstone is about to erupt. The processes that created the crack are not even all that mysterious.
SNS is reporting that an engineer gave a more rational explanation for how the crack formed: “Apparently, a wet spring lubricated across a cap rock. Then, a small spring on either side caused the bottom to slide out. He estimated 15 to 20 million yards of movement.”
Though the speed with which the large crack formed might seem earth-shattering, these kinds of landslides are not that uncommon in the area on a smaller scale. This one just happened to be especially voluminous.
