The three victims were reportedly part of a group of seven swimming near Shannon Falls outside Squamish, British Columbia. According to eyewitness reports, Megan Scraper slipped and fell 30 meters into fast-moving water just above the falls. Alexey Lyakh and Ryker Gamble are believed to have jumped into the water to try and save her, but all three were swept over the falls. Their bodies were recovered the next day.

According to the CBC, Gamble and Lyakh started High on Life with two other childhood friends. Previous videos posted by the deceased and the High on Life channel show lots of exotic travel as well as some high-risk outdoor activities, including cliff jumping and crossing decrepit rail bridges. Some of the group’s YouTube videos emphasize the danger of certain activities. One video, featuring Gamble descending a harrowing natural water chute, is accompanied by a disclaimer stating that “Our team has been trained and involved in gymnastics, diving, stunts, and the extreme sports community for over a decade,” and warning others against trying to replicate what they see.

The accident has nonetheless added new fuel to long-running debates about the potential danger of social media featuring risky activities. That’s in large part because the High on Life group has previously been accused of violating safety and natural preservation rules. In 2016, Gamble and Lyakh posted video showing themselves leaving designated trails in Yellowstone National Park and walking near the Grand Prismatic Spring, an ecologically delicate and potentially dangerous hot spring. They were ultimately sentenced to seven days in jail and apologized for their behavior.

Members of the group, including Gamble and Lyakh, were also accused of violating rules elsewhere. Those incidents included using bicycles in prohibited areas in Death Valley National Park; swinging from the Corona Arch rock formation in Utah; and wakeboarding on the sensitive Bonneville Salt Flats in the same state. At least some of those incidents were filmed, according to citations.

High on Life currently has more than 500,000 subscribers, no doubt partly thanks to such high-risk stunts. Some have argued that the quest for thrilling footage led the team to take more extreme risks, without the safeguards or oversight that might have been imposed by a more conventional media organization. That dynamic mirrors the documented tendency of algorithm-driven media platforms to encourage ideological extremism among users.

In a video message posted after the tragic deaths, other members of the High on Life team praised the trio’s legacy. “They lived every single day to its fullest,” the memorial stated in part. “They stood for positivity, courage, and living the best life that you can, and they shared and taught their values to millions of people worldwide.”
