Dry Falls is a 3.5 mile long scal­loped precipice in central Wash­ing­ton. Ac­cord­ing to the current ge­o­log­i­cal model, cat­a­stroph­ic flooding chan­neled water over this 400-foot (120 m) rock face at the end of the last ice age. 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.
