Wyoming’s Overnight Canyon
We’ve received a great deal of questions recently about a giant crack in the earth that recently appeared on a ranch where we operate in the southern foothills of the Bighorn Mountains. Thinking it was interesting, but not knowing that it would get so much attention, we posted a photo on our Facebook page. After being shared more than 7,000 times, we started receiving a flood of questions and comments.
Here’s what we know so far: we have two outfitted camps on this ranch. We hunt here every year and have been doing so for decades. Our guides first noticed the giant fissure in early October. We couldn’t tell what had caused so much earth to suddenly move, but it certainly had not been there long.
A couple of weeks later, an engineer from Riverton, WY joined us to take a closer look. We walked the perimeter and took estimates on size using a rangefinder. We estimated the crevasse to be about 750 yards long and about 50 yards wide.
According to the engineer, there was a cap rock being lubricated by a spring. Additionally there was a spring running across east to west, which then caused the entire thing to slide north. The engineer estimated about 15 to 20 million yards of movement. According to the USGS, there has been no seismic activity, so we have no other possible explanations at this time.
Since posting the photo on Facebook, we’ve received countless offers from geologists, scientists and reporters from all over the world to come and take a look at this fascinating event. It truly is incredible to look at, a canyon that formed almost overnight – a mountainside that seems to have suddenly collapsed.
