This group of WSU professors and local residents are discussing how to best preserve the site from inundation. It was decided to build a coffer dam, one which failed to work even in the slightest. This photo gives a good idea of just how immense the cavernous Rockshelter is. Today, there stands about forty-feet of the Snake and Palouse Rivers atop the site. The only thing visible is the top of the coffer dam.
