The trails of Tuolumne Grove, a popular site in Yosemite National Park, wind through forests of pine and giant sequoias, the largest trees on earth. On July 19, after hiking about a mile into the grove, Angela Lin, 29, and her friends heard a snapping sound above them.

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.
