Input: A large crevasse that has formed a mini canyon in the Bighorn Mountains of Wyoming is likely a slow-moving landslide, a state geologist said. 
  
 The crevasse that developed on a grassy, sloped area at the southern end of the mountain range is about 750 yards long and about 50 yards wide, according to outfitters with SNS Outfitters & Guides who posted a photo of it on their Facebook page. 
  
 "It's a pretty good size," Seth Wittke, geologic manager with the Wyoming State Geological Survey, said Friday. "I wouldn't say it's huge. I think there's much bigger ones that we've seen in the state. It's definitely not a small one, I would agree with that." 
  
 The owner of SNS was in the backcountry Friday and not immediately available for comment. 
  
 Wittke said the landslide could be the result of springs in the area. 
  
 "And so what may be happening is that you may have excessive water infiltration into the hill slope that's causing the instability in it," he said. 
  
 It's not clear when the landslide started and whether it is still moving, Wittke said, adding his only information about it comes from pictures and anecdotal evidence. 
  
 State geologists have not been able to inspect the crevasse yet. 
  
 "It's not as big a priority because it's not threatening infrastructure, or population centers or anything like that," Wittke said. "Although we do think it's significant and we want to go look at it. We just have to find the time to get up there." 
  
 Wittke said the State Geological Survey has mapped about 40,000 landslides throughout Wyoming. 
  
 "They do occur in the state and they occur pretty much everywhere within the state," he said.

 Information from: Powell (Wyo.) Tribune, http://www.powelltribune.com ||||| Story highlights A hunting guide company posts pics about a geological phenomenon in Wyoming 
  
 Experts speculate that a wet groundwater spring may have contributed to "the crack" 
  
 (CNN) Some call it "The Crack." To others, it's "The Gash." And a few may see it simply as a case of the Earth opening up and swallowing itself. 
  
 Whatever the label, the emergence of the new geologic phenomenon in Wyoming's Bighorn Mountains is impressive. 
  
 SNS Outfitters & Guides first alerted the world about it last Friday, in the form of a picture that shows a rolling, largely barren landscape broken up by a sliver that was itself broken up -- not unlike a puzzle piece that doesn't or hasn't been fit in. 
  
 "This giant crack in the Earth appeared in the last two weeks on a ranch we hunt in the Bighorn Mountains," said the company, which offers guided elk, antelope, deer, moose and bear hunts. "Everyone here is calling it 'the gash.' It's a really incredible sight." 
  
 Subsequent photos popped up on social media showing the formation's considerable scale.

Just in time for the ancient and unspeakable ones to rise from their underground caverns on Halloween, KTVQ reports a large crack has mysteriously appeared in Wyoming's Bighorn Mountains. "Everyone here is calling it 'the gash,'" SNS Outfitter & Guides writes on its Facebook page. "It’s a really incredible sight." The local hunting company first snapped photos of the crack last week and estimates it's 750 yards long and 50 yards wide. According to CNN, the crevasse is many stories deep with a number of different levels stepping down into the earth. "It's a pretty good size," Seth Wittke, geologic manager with the Wyoming State Geological Survey, tells ABC News. "I wouldn't say it's huge. I think there's much bigger ones that we've seen in the state. It's definitely not a small one." Wittke says state geologists haven't gotten to check out the crack in person yet—it's not urgent because it's nowhere near infrastructure or settlements—so they aren't sure when it started or if it's still moving. The geological survey is calling the phenomenon an "apparent active landslide," for which it blamed groundwater, CNN reports.
