While going through the archives I came across the Woodford formation, I stretched it out of curiosity, The swirling patterns of the lay seemed to be  setup to form a holographic image with light reflection. The image is not something I recognize but might be a challenge for the members of the site. Is it a lunar landscape, global view of earth as if from satellite etc? The dark tufts act as a dark spots.. marking a particular spots?  I plan to review through all the archives now.
