A 26-year-old woman fell to her death Sunday while descending from the summit of Half Dome within Yosemite National Park.
Hayley LaFlamme, of San Ramon, Calif., plummeted about 600 feet from the cabled route on the granite monolith. The incident is under investigation but thunderstorms were in the vicinity most of Sunday morning and the incident occurred at about noon.
Stormy weather makes for extremely hazardous conditions. Those planning to climb Half Dome should consult a web page set up by the park to show how to prepare for the endeavor.
The last hiker to have died on Half Dome was Majoj Kumar, also from San Ramon, on June 13, 2009. The most recent fatal accident on Half Dome's cabled route before that was in 2007.
