Abstract
Recent observations in the interior of Washington State indicate in no unmistakable terms that in late geological times the entire drainage of the region has repeatedly undergone great vicissitudes. Its juvenile lines have been profoundly disturbed, displaced, and variously modified. By floods of lava on the one hand and on the other hand by advancing glaciers the original river courses have been completely lost to view. A notable and concrete illustration is the Big Bend of the Columbia River- that stretch of the great stream nearly 200 miles long lying between the mouths of the Spokane and Snake rivers.
