YOSEMITE NATIONAL PARK, Calif. -- Yosemite National Park officials say search-and-rescue crews have recovered the body of a missing 6-year-old boy who was swept away in the Merced River along with his elder brother.

Park spokesman Scott Gediman says Jacob Adams' body was found Thursday morning, wedged under a large boulder about 50 yards downriver from where he went missing.

The two boys were swept away Aug. 15 on a popular but treacherous stretch of the river on the Mist Trail. Hikers recovered the body of 10-year-old Andres "Andy" Adams that same day, about 150 yards downstream from where the family entered the water.

The Southern California family had been hiking near the Vernal Fall Footbridge with a church group, whose members were cooling off in the river when a current carried the boys away.

    The setting sun hits Horsetail Fall at just the right angle to light it up as if it's on fire, in Yosemite, Calif. This natural phenomena occurs for just two weeks in February and is reminiscent of the old firefall of burning embers that park employees pushed over Glacier Point to entertain guests until 1968.
