2007 Castle Cliffs rock fall

A close perspective of source area on cliff, circled in yellow.

A rock fall from the Castle Cliffs north of the National Park Service stables occurred causing numerous rock impacts sounded like thunder and lasted about 30 seconds. Inspection in the morning revealed a fresh boulder in the gully directly north of the stables leading up to Sunnyside Bench and two large boudlers resting approximately 100 m upslope of the Valley Loop Trail north of the National Park Service stables. One smaller flyrock boulder fell onto the Valley Loop Trail in the talus slope section north of the stables. Considerable vegetation on the talus slope was damaged, with several live oaks completely shattered and many others broken and scarred.
