I just talked to Greg Stock, the Park Geologist, about the recent rock fall. He wants to warn climbers that the Slabs Approach should be avoided, and at all costs avoid Bushido Gully. The slabs and the base of the right side of the wall are covered with fine pulverized granite dust, and there are also dislodged boulders precariously perched throughout the area. There has not been any rain to clear anything out and we probably won't have a sizeable amount for a while. There is also still a high possibility that more rock fall will occur in the same area. It probably is not connected with the recent active zone further to the East (the fish-shaped chunk), but there is no way to totally rule that out.
The RNWF of HD was not immediately affected and climbers can approach it via the shoulder of HD below the cables by going on the hikers trail past Nevada and Vernal falls.
