River surfers come from far and wide, and form tight friendships as they look out for each other on these dangerous waters.
The Mountain Wave, located on the Kananaskis River, was created from a flat river section in 2014 by the organization Surf Anywhere for the Alberta River Surfing Association.
It took about a decade to get the permission and the time needed to build this wave on public land less than an hour west of Calgary — a process that involved placing boulders in the river to form a channel.
Now, it’s a permanent wave that surfers can ride for free, with the added benefit of ending up in roughly the same spot that you start.
And even in the extreme cold of Alberta’s unpredictable weather, river surfers are out there taking advantage of it.
The following photos and video were taken by Christina Ryan, who spent some time getting to know the surfers and what attracts them to the sport.
