'That Is Crazy': Locals Watch as Mudflow Surges Through California Canyon -- Storyful

A Californian hiking enthusiast was on hand to capture what he called the “incredible” moment a mudflow came sweeping through Sheep Canyon, near Wrightwood, California, on Sunday, August 20, carrying wood and debris along with it. The footage, by X user @TransverseDream, shows the debris approaching as he and two children react. “Before it started we could hear rocks and logs booming and crashing up in the landslide,” @TransverseDream posted on X, formerly known as Twitter. @TransverseDream said that he’d been up in the canyon previously, where he noted a “lot of loose soil deposited by avalanches & snowmelt”. He said he was therefore “expecting at least mud flows” from the downpours brought by Storm Hilary. Highway 2 in Wrightwood was closed on Sunday, local officials said. Roads were also closed in nearby Phelan due to the Sheep Canyon flooding.
