One young boy is dead and another missing in Yosemite National Park, where the two were swept down the Merced River below the Vernal Fall Footbridge.
Park officials say the two boys -- a 10-year-old and 6-year-old -- were on a hike with their family when they stopped near the footbridge on Wednesday afternoon.
The family, from southern California, had begun their hike at the Happy Isles Trailhead and hiked approximately one mile, where they stopped at the footbridge, a park release said.
"The group was in the river and the two boys were swept away by the current. Approximately 150 yards down river, the 10-year-old boy was pulled from the river and CPR was initiated by a park visitor," the release stated. "Yosemite National Park rangers continued resuscitation efforts, which were unsuccessful, and the boy was pronounced dead."
While those efforts were ongoing, other rangers began looking for the 6-year-old in the Merced River between the Vernal Fall Footbridge and Happy Isles. Search efforts for the boy were continuing Thursday morning, the park reported.
The Mist Trail remains open during search-and-rescue operations. Portions of the trail may close throughout the day to accommodations the search. The names of the victims will not be released.
It was a little more than a year ago when three young adults were swept down Vernal Fall. The area where the three were swept away on July 19, 2011, is signed as a dangerous area, and the group had crossed a metal guardrail placed there to keep visitors away from the fast-moving water. Two of the bodies weren't recovered for nearly five months.
