2006 Half Dome Northwest Face rock fall

White rock fall dust clouds rise and partially obstruct the view of Half Dome from the northeast. Tree silhouettes frame Half Dome on both sides.

A large rock fall from a low area, slightly southwest of the northwest face of Half Dome, above "Bushido Gully". After detaching along a joint from beneath a prominent curving arch, the slab slid down a steeply inclined surface for 60-80 m and then impacted a lower-angle section of the face where the rock began to break apart. The rocks then fell into Bushido Gully and the central gully beneath the northwest face, producing a substantial dust cloud that was observed throughout eastern Yosemite Valley and Tenaya Canyon.
