Back in August 2015, two high school students were asleep in a tent in the Upper Pines Campground when an oak limb fell, killing them both. And in 2012, a concessions worker was killed when a tree fell on his tent cabin during a windstorm.

Tuolumne Grove is home to about two dozen mature giant sequoias and is a popular destination in the park. The area was temporarily closed following the incident, park officials said.
