Tuolumne Grove is home to about two dozen mature giant sequoias and is a popular destination in Yosemite. The area was temporarily closed after the incident.

According to reporting by San Francisco Gate, Angela Lin was hiking with her boyfriend David Hua, and two friends in Tuolumne Grove on July 19 when the tragedy occurred. Hua says the group heard a loud cracking sound followed by several falling branches just seconds later.

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.
