yosemite national park | For Hikers, Feared Swept Over Falls

Park officials began a search at Yosemite National Park on Tuesday afternoon for hikers who may have been swept over the park's falls.

According to the Associated Press, Yosemite officials received multiple emergency calls on Tuesday from witnesses who saw one or more hikers go into the water and over Vernal Falls, which is 317 feet high. At the top of the path to Vernal Falls, a guardrail seperates Yosemite visitors from the water, and yet accounts suggest that 13 people have fallen over and died since records began.

Witnesses provided various reports of what happened to Yosemite officials and reporters.

Witness Jacob Bibee told CNN affiliate KGPE-TV, “I saw the man’s eyes when he went over the falls. That was devastating."

Witness Dean Sabo told KGPE, “I saw two that were holding each other and one that was floating alone through the water. And the reason that I looked was because this woman was screaming, running along the edge of the water."

NBC Fresno affiliate KSEE reports that, according to witnesses, a man and woman climbed over the guardrail for a better view, and possibly encouraged their children to go over as well. The man and woman began to slip before the children climbed over. Another man jumped over the guardrail to help, but also fell over the edge, KSEE reports.

Park spokeswoman Kari Cobb said that rangers quickly shut down Mist Trail, and searched the Merced River corridor for any possible victims. While the search was stopped when darkness fell, it is expected to resume today.
