2 young people were killed early Friday after a limb from an oak tree fell on their tent as they slept

A limb fell from a black oak tree in the park's Upper Pines Campground It hit the tent that the two campers and killed them in at about 5am on Friday

Park spokesman Scott Gediman on Friday morning declined to release the ages or any details about the two, describing them only as under age 18

 it is unclear why the tree limb fell, but officials said it wasn’t windy that morning, Gediman said.
“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.
