Here is a good view of the nice riparian area along the Mill Race Path in Springfield, OR, a great place to walk or bike. And those are NOT fake clouds!

Definition of 'riparian': "A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the fifteen terrestrial biomes of the earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants." (Quoted from Wikipedia)
