These rocks stand in a river in a remote valley in the Pacific Northwest. No plaque records the names of the artists who spent hours in icy water selecting, lifting and carefully balancing rocks. No museum houses these assemblies, preserving them for future generations to ponder. They will stand balanced only until high water or ice tumbles them back into centuries of river flow. They are art nonetheless, silent sentinels that mark (for a time) the collaboration of human effort and imagination with the wonder of river-worn rocks in a stunning gallery of moving water, standing trees and changing skies.
