YOSEMITE -- A male hiker fell and died Saturday while climbing Yosemite's Half Dome, park rangers said.
Manoj Kumar, 40, of San Ramon, fell from the granite monolith at 3:40 p.m., Yosemite Ranger Scott Gediman said.
Kumar had reached the summit and was descending when he slipped and dropped about 100 feet, the park service said. Park rangers were taken by helicopter to the scene, where Kumar was pronounced dead from severe trauma.
Gediman said there are indications the hiker was using the cable handrails that help climbers make the 17-mile round-trip hike, which begins in Yosemite Valley and ascends nearly 5,000 feet.
Never miss a local story.
The weather Saturday made for dangerous conditions, and 41 Half Dome climbers were escorted down by rangers.
"Right now, the weather is cold and cloudy. Hail has been reported on Half Dome today and the granite gets very slippery," Gediman said.
It wasn't clear if Kumar was with a group or alone.
The last death at Half Dome was that of Japanese hiker Hirofumi Nohara, 37, who slipped off of cables June 16, 2007.
Saturday's death was witnessed by a number of other hikers, Gediman said, and an investigation has been launched.
