Two hunting guides found a small crack in an isolated ranch near Ten Sleep in north central Wyoming last September. A few weeks after they returned, what they saw shocked them as the small crack now measures 45 metres wide and 650 metres in length. 

"There it was, this huge slide or crack or whatever it is," owner of SNS Outfitter and Guides Sy Gilliland told KUSA. Dubbed as "The Crack" while others call it "The Gash" or "Crevasse," these hunting guides, who were scouting for antelope last Oct. 1, found the massive hole in the ground and estimated it to be 100 feet deep in some areas.

Geologists believe that the crack found was a result of a landslide. Although The Gash has been making rounds on the Internet, Tom Drean, geologist from the Wyoming state, said that this phenomenon happens all the time.

According to SNS in an update posted on its Facebook page, the crack appears "steep cliffs, earthen towers, and massive boulders." The size of Crevasse was impressive and so was the speed of formation.

"The mass geologic movement in the remote area where no people or property are directly at risk came to light last week when commercial hunters in Wyoming discovered it and posted photographs and commentary on their firm's Facebook page," as per Reuters. 

According to the Wyoming Geological survey, because of the unstable hillside, water coming down the hillside loosed the dirt and gravity did the rest. "Extended saturation like a wet spring and summer leads to more weakness, and then the hillside shifted and caused a landslide with an associated large crack."

Experts, nonetheless, strongly suggest that people should not go near the gash although it does not pose an immediate cause for alarm.
