"Brought from Montana and deposited by an ice berg on the banks of the Columbia River"
interesting stuff Dean & great page!
Thank you Radek, it was "fascinating" to me when I discovered this Ice Age Flood stuff. It is neat to walk up to this plateau and find a large solitary granite boulder just sitting there all by itself. Hard to believe that the water level could have been higher than where you are standing in order for this boulder to have been dropped there. Mind boggling.
