During the week of March 20, there was a significant rock-fall event in the main descent gully at San Ysidro.
In this event, at least 30 cubic feet (3,000-lbs?) of rock fell from high in the descent gully, from opposite the start of "Scrub Job." It is obvious that a considerable amount of instability remains and that smaller rock falls are happening regularly. A refrigerator-sized chalk-stone at the top of the gully (8 feet below the large oak tree) appears to have been undercut and could release.
Fortunately, falling rock has thus far tended to stay in the gully and does not appear to immediately threaten climbers on any of the major routes--with the possible exception of climbers at the bottom of "Great Race." Be extremely cautious when using the descent gully.
