Washington State Highway 261

This road will get you to Palouse Falls State Park and Lyons Ferry.  The falls are the tallest in the state.  They just seem to appear out of the basaltic cliffs and leap out into space to fall 183 feet.  It flows into a wild canyon on its way to join the Snake River.  One needs to wander around to get prime shots.  Staying over night in a tent provides som great color in the clouds.
