Two
deformation events observed in summer 2005 associated with
precipitation followed by freezing air temperatures
There were two large storm
events in the summer of 2005 where significant precipitation was followed by
freezing air temperatures.The initial
hypothesis is that ice formed rapidly in the cracks and wedged the rock apart.Both of these events registered
deformations (up to 20 mm on September 10) on two of the extensometers.
