On Christmas Eve, five trees fell onto the hillside trail with one crashing onto a group of hikers, park officials say.
A 29-year-old man was pinned by the trunk of the tree.
He did not survive.
A woman in the group was injured by falling debris. Another man made it out without any injuries, park officials say.
They believe the winter storms over the past week and a half may have contributed to the trees falling.
At this time, the hillside trail is closed.
It will reopen after the holiday weekend.
