3 Hikers Swept Over Edge of Yosemite's Vernal Fall, Search Underway

A section of Yosemite National Park has been closed after three hikers were apparently swept over the edge of the park's famous Vernal Fall Tuesday.

From this story on CNN:
A search is under way in Yosemite National Park for as many as three people who may have been swept over the 317-foot-high Vernal Fall on the Merced River in eastern California. Park rangers have closed the Mist Trail to the fall until at least noon Wednesday, saying they are conducting a search after receiving unconfirmed reports of one or more visitors being swept over the fall. Witnesses told CNN affiliate KGPE-TV that three people were swept over the fall around 1:30 p.m. Tuesday.

_"I saw the man's eyes when he went over the falls. That was devastating," witness Jacob Bibee told KGPE. Other witnesses said two men and a woman went into the water and over the fall into a rocky pool below. "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," witness Dean Sabo told KGPE.
