Dave, from above, drops rocks on overhang. It moves! It moves again, but does not fall.

A New Side by Side Comparison

by Bob Zimmerman (posted January 23, 2006)

With the help of the comparison that Charles Danforth had done after the first collapse, I have made a new side-by-side comparison below. Note the differences. Apparently the rocks under the overhang dropped off, leaving that overhang in a very precarious position. It is so precarious that it moved when hit by one of Dave's thrown rocks.
