2009 Rhombus Wall rock fall

A billowing white dust cloud rises from a cliff face above a sloping talus cone.

This was the largest in the series of rock falls from the Rhombus Wall on 26 August 2009. The majority of the debris that traveled beyond the edge of the talus slope landed just east of the valet parking gate and just west of the Royal Arches Creek streambed. Five vehicles were damaged in this area, including a minivan that was fully penetrated by a rock fragment, but there were no injuries.
