2016 Dog Rock rock slide

View from above looking down at fresh boulders and downed trees covering both lanes of a road and debris extending down the slope below.

A substantial debris flow blocked both lanes of El Portal Road at Little Windy Point. Both lanes were covered by rock debris and boulders. The rock mass slid down the lower slab and landed on the road, depositing rock blocks across both lanes of Hwy 140. The rock slide destabilized a 10 m tall tree that came to rest with its roots on the rock slide deposit and crown leaning against the source area.
