After video of a pair of young men carelessly throwing pieces of rock off a cliff face at a popular Canmore hiking trail went viral this week, hikers in the area are decrying their actions as ‘stupid’ and ‘dangerous’. 
  
 In the video, two young men are shown taking turns throwing some large rocks over the edge of a cliff, unaware of the potential risk to anyone below. 
  
 It’s since been removed from social media, but many people who frequent the area say the stunt could have had serious consequences. 
  
 “It’s pretty silly. It’s dangerous,” said one woman. “You’re disrupting nature. You don’t know what’s underneath there and you might be causing a whole bigger issue.” 
  
 Even visitors to Canada who are enjoying the Rocky Mountains for the first time in their lives think that throwing rocks is a ridiculous idea. 
  
 “Oh that’s stupid. There’s no point. It’s just dangerous. I can’t believe that people are doing it,” said Simon Doering from Germany. 
  
 “It’s a threat for people’s life. There’s no purpose of throwing rocks,” said Marwa Haddra, who is from Tunisia. “If there are people who are doing this, there should be signs or restrictions.” 
  
 Other people who come to the trails of Mount Rundle on a regular basis say that the idea of someone throwing rocks is ruining the enjoyment of the area. 
  
 “It was frustrating. There are a lot of people who do fun stuff in the mountains and they shouldn’t have to worry about rocks hitting them,” said Chris Cobin. 
  
 Cobin says that some signage could help, if only to communicate the rules to hikers who aren’t as experienced as some. 
  
 Al Black, chairperson of the Climbers’ Access Society of Alberta, said he was sad when he first saw the video of the rock throwing. 
  
 “Here’s this situation that’s on camera that we know is just going to blow up. It’s just two guys out having fun. They’re just throwing rocks off the cliff and they have no idea about what they’re doing.” 
  
 Black says that the East End of Mount Rundle is a very popular climbing spot so the odds are pretty high that there was someone around them who could have gotten hit. 
  
 “They could have been killed. A rock that size, hits you in the head, you’re gone. If it hits you in the arm, you lose an arm. That’s the consequence of it.” 
  
 He says that it’s great that no one was hurt and signage could be a great idea to include to help inform those who just aren’t aware of the risks. 
  
 “Putting it up on the cliff, maintaining the sign could be really helpful to protect the recreating up there.” 
  
 Meanwhile, RCMP did say that they opened an investigation into the incident and that it led them to one of the men in the video. 
  
 They opted not to lay any charges because they determined that the group was inexperienced and didn’t understand the harm that could have been inflicted. 
  
 (With files from Brenna Rose) ||||| A video of two people throwing huge rock chunks off Mount Rundle near Canmore — potentially putting climbers and hikers at risk of injury — is drawing outrage and calls for better signage. 
  
 The video — originally posted to Instagram but since deleted — was copied and posted to a climbers' Facebook forum. 
  
 "I was really pissed off," long-time Calgary climber Adam Ghani told CBC News. 
  
 "It just really, really angered me. I am a climber so when I see stuff like that, it endangers people who are climbing on that cliff. I have climbed on that cliff numerous times, not far from where they were throwing those rocks off." 
  
 A video of rocks being thrown off Mount Rundle was posted and deleted from Instagram but a copy was shared with a climbers' Facebook forum. (Submitted) 
  
 CBC News has chosen not to identify the individuals in the video because a member of the climbing community has spoken to them and determined they weren't acting maliciously, but didn't realize their actions were dangerous. 
  
 Ghani agrees. 
  
 "I believe they don't really understand the consequences. They just think it's fun and not wrong. I don't think they were doing it intentionally," he said. 
  
 Police want to talk with people in video 
  
 Canmore RCMP are now involved and want to know more. 
  
 "We have received a complaint and we are investigating it," Sgt. Stan Andronyk said. 
  
 "It is definitely a safety concern to see those types of actions. We would like the public to be considerate of everyone in the area and to consider the potential consequences and actions that may seem harmless at the time. We definitely would like to speak to the people involved and determine what their intentions were."

 A public safety specialist with Alberta Parks Kananaskis Country says the actions did put climbers and hikers at risk as there are paths and hiking areas directly below where the rocks were thrown. 
  
 Mike Koppang says he gets complaints, but they aren't that common, and it's likely the people in the video weren't aware of what could happen.

 Meanwhile, Ghani would like to see better signage alerting people to the hazards. 
  
 "The signage should be better. There could be a collaborative effort where we could get together and start putting signs on popular cliffs where there are multiple users, hikers and climbers," Ghani said. 
  
 "There is that opportunity." 
  
 This isn't the first report of rocks thrown from mountains. A climber told CBC News just weeks ago he was twice subjected to rocks thrown from Mount Yamnuska while climbing. 
  
 Alberta Parks said at the time it had updated its website to explicitly remind Yamnuska visitors to not throw rocks from the mountain and is considering installing new signs along the route, as well.

A:
Video footage from a mountain trail that shows visitors throwing huge rocks off a precipice has stirred outrage in the Canada climbing community. The public became aware of the incident after video that recently appeared on Instagram before being taken down appeared to show hikers on Alberta's Mount Rundle as they threw chunks of rock down a cliff face on a popular Canmore trail, per CBC. The Royal Canadian Mounted Police became involved after the outcry from viewers who believed the people in the video were carelessly putting the lives of other climbers at risk. According to CTV, the RCMP have made contact with those in the video. However, authorities said they have decided not to press charges because the individuals did not know what they were doing posed such a risk. Others said the video just goes to show that signs warning of the dire consequences of this sort of carelessness would make a big difference. Climbers in particular seemed the most concerned about the incident because it occurred where unseasoned hikers could cause serious injury to those scaling the cliffs below. One climber told CBC, "There could be a collaborative effort where we could get together and start putting signs on popular cliffs where there are multiple users, hikers and climbers."
