Three hikers in California died after jumping into a waterfall, and they failed to resurface.

The Placer County Sheriff’s Office said on June 18, deputies made contact with three hikers who said that three other men in their group jumped into Rattlesnake Falls in Soda Springs, California, but did not come out of the water.

Deputies described the terrain as “extremely remote and difficult to access,” which made rescue attempts “especially challenging.” The sheriff’s office added that Rattlesnake Falls, northwest of Lake Tahoe, was located “several miles in on a steep and difficult hiking trail.”
