Comments:
The lookers right side of rockface appeared to have slid at some point before we first saw it at 1 pm Monday, and then slid to the ground by the time we saw from the same vantage across the valley at 3 pm. Good reminder that smooth rock faces, especially unsupported ones like this notorious one are very unpredictable. Slide did not seem to corolate with a significant rise in temperature or loading.
