MOUNT SI, Wash. -- A 15-year-old boy had to be rescued from the rocky summit of Mount Si after he slipped and fell down a steep rocky area Saturday morning.
The U.S. Navy sent a helicopter to rescue the teen, but it had to circle for a good half hour because the summit was hidden by low, thick clouds - too foggy for rescue crews to get close enough.
Back down at the trailhead, a few dozen search and rescue volunteers set off on foot, trudging up four miles as a back-up if the chopper couldn't get to the teen first.
The victim is a high school student from Kennedy Catholic High School in Burien. He was there with 30 members of his cross country team. They say it's tradition to hike up Mount Si to the jagged, rocky summit known as the Haystack.
Once they reached the top, two boys slipped. The 15-year-old boy fell between 40 to 90 feet. He hit his head and was knocked unconscious.
The other boy was stranded, but not injured.
Around 2 p.m. the clouds cleared enough for the chopper to lower a medic, who hoisted the boy back up and airlifted him to Harborview Medical Center. He was reportedly talking and alert, but with serious head injuries.
Mount Si lies on the western edge of the Cascades and is about 4,167 feet high. It's located about 31 miles east of Seattle.
