Hmm .. I was right under the vertical part on a day like that. Most of the falling ice would hydroplane away from the face. Then the wind calmed, and a chunk about 60 ft across landed about 30 ft away. Time to get out of Dodge City. Watkins, Muybridge, and Fiske all did wonderful pale sky shots of El Cap by virtue of blue sensitive films. My sky was white due to snow conditions, like this one. That kind of treatment often renders a sense of scale and monumentality to the scene. There is a better known shot taken by AA from the same spot much later, which would make an interesting comparison. His careful timing with respect to the pattern of ascending vapors or fog is apparent in both. Few of his disciples had the same level of poetic timing. The Zone System can't teach you that!
