    Re: Yosemite Rockfall Along Horsetail Fall

    From this photo in Fred's link, it appears the the rock-slide occurred on the left (west) side of the waterfall:



    From other photos this appears to have undercut the knob on which the waterfall flows and that knob might well be the next to go.

    The main monolith takes a concave turn toward the Dawn wall, North America wall, and El Cap (Horsetail) Falls. This comprises a "book" (like a partially opened book) which funnels everything falling in this general area into the big talus pile below. The boulders are both whitish from the main monolith and darker andesitic rock from the North America-shaped inclusions up there. This recent Rockwall looks like typical joint spelling probably accelerated by frost wedging during the exceptional past winter.

    Spalling, not spelling. Why this darn dumbphone leave things alone and not try to resell (repsell), speak or small (spall) everything? I'd like to toss it off that cliff!
