Ryker Gamble, Alexey Lyakh, and Megan Scraper were reportedly walking along the edge of the falls when they slipped and fell about 30 yards, according to the Squamish Royal Canadian Mounted Police.
“Squamish Search and Rescue (SAR), Lions Bay SAR, BC Ambulance, Squamish Fire, BC Parks, and Squamish RCMP attended to the scene in order to coordinate the search efforts,” Squamish RCMP said in a Tuesday press release.
According to the Canadian Broadcasting Corporation, witnesses said they saw Gamble, 30, and Lyakh, 30, dive into the pool above the falls to save Scraper, 29, who fell from rocks at the top and was carried by a strong current. But none of them survived.
The trio was known for its adventurous travel videos. In 2011, Gamble and Lyakh created the YouTube vlog channel "High on Life" to showcase their performances of daring outdoor tricks and stunts at well-known locations.
And in 2016, the two made headlines after walking off a designated path in Yellowstone National Park to get closer to the famous Grand Prismatic Spring.
Last January, they were reportedly sentenced to seven days in jail for violating rules at multiple U.S. national parks and banned from American public lands for five years, according to CBC.
"High on Life" has over half a million subscribers on YouTube, and over 1.1 million followers on Instagram.
On Friday, the YouTube channel released a video tribute in memory of Gamble, Lyakh, and Scraper.
"High on Life" also started a fundraising campaign to support the victims’ families’ expenses “that come at an impossibly difficult time like this.”
In addition, the channel published a passage written by Gamble and Lyakh and encouraged subscribers to use the hashtag #HOLInspired to share their thoughts on social media.
“What do you want to do in your life? What makes you tick? What makes you feel awe? Don’t be misled into thinking that you’re supposed to do anything. You are supposed to do only what you chose to do,” they wrote. “The world is vast and full of possibilities. Follow your bliss. Get out of your comfort zone. Stop looking for reasons why you can’t and look for reasons why you can. And … if you can, you should."
