Extinct Flow

Taken at the Dry Falls Interpretive Center near Sun Lakes in North Central Washington.

 

"Geologists speculate that during the last ice age catastrophic flooding channeled water at 65 miles per hour through the Upper Grand Coulee and over this 400-foot (120 m) rock face. At this time, it is estimated that the flow of the falls was ten times the current flow of all the rivers in the world combined."
