During ice ages, Columbia River poured over these cliffs.  Now known as Dry Falls.

Some rain fed lakes remain. 

One lake has no outlet.  It is salty.  Soap Lake.  A poster in the town of Soap Lake reveals plans for the world's largest lava lamp.  Anything to be remembered.
Dry Falls
Before getting to Dry Falls, I rode along Banks Reservoir where water is stored for Columbia Basin irrigation projects.
