River waves are a beautiful thing. And there are plenty yet to be discovered. This group of adventurers, who together comprise the YouTube channel “Sickos,” discovered a trapped body of water during their travels and decided to create a wave, similar to the one at Waimea Bay. The concept is simple: dig a small trench to allow the trapped water to reach the ocean, then let gravity do the rest. Water is a powerful force. Well, this river wave got a wee bit out of hand. Thankfully, the only thing broken were boards.
