Blending Blue and Green

The McKenzie River flows past lava fields, dropping over waterfalls and forming the rainbows of my last post.  As it continues downstream, it sinks into the lava, eventually disappearing from the surface for a while, re-emerging in a stunning jewel called Blue Pool.

This very deep, very clear pool rises from the rock and reforms itself into a surface river.

Once on the surface again, it resumes its mad dash west toward the Willamette.
