The park’s dispatchers received numerous 911 calls for medical assistance. When they arrived to the campground, the youngsters were dead.
“Fallen branches like this one are a common occurrence across the park,” he said.
Situated at 4,000 feet in the Yosemite Valley near Curry Village, the campground with views of the park’s most iconic rock formation Half Dome is the chosen destination for families site.The youngsters’ deaths add to what appears to be a long history of tree-related fatalities at the park.
Two tourists were killed and nine were injured in 1985 when a 25-foot oak branch fell 15 feet onto an open-air tram carrying 50 passengers.
The same series of events happened in 1992, when a branch from an oak tree fell onto another touring bus, injuring seven people. The visitors were stopped on a main road near the Merced River to observe Yosemite Falls. The large branch came crashing as the tour guide spoke.
In Friday’s incident, drought may have played a role but it’s too early to say, Gediman said. Bark beetles steer away from oak, so he said that likely didn’t cause the limb to fall.
