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.

Google software engineer Angela Lin, 29, died during a fatal accident at Yosemite National Park where a large tree branch fell on her.

After Lin's death, Tuolumne Grove—the area where she and her group had been hiking—was closed to the public for nearly a week.
