This is the second geologic incident since my recent visit to the SW of Colorado, Utah and Arizona, first was the massive rock slide in the Black Canyon of the Gunnison a short 8 weeks or so ago and now this...! It proves the world is a dynamic place and changes, even ones that normally occur on geologic time scales of millions of years, can and do occur, in an instant. I am privledged to have experienced these wonders prior to their falls and hope many will appreciate the fragility of most of our natural wonders, get out there and experience nature's grandeur knowing nothing is forever.
