2008 Ledge Trail rock fall

A row of trees in front of a steep rock cliff. White dust clouds rise from behind the trees.

A large rock fall occurred from above the Ledge Trail on Glacier Point, about 200 m above the east-dipping joint-controlled ledge of the Ledge Trail. Rock debris impacted the Ledge Trail ledge and moved downward to the east, onto the top of the talus slope at the base of the ledge. Numerous large Douglas Firs were snapped or toppled by boulders moving down the talus slope below the Ledge Trail.
