Your post is interesting and certainly deserves further investigation. It did trigger several memories from a couple of years ago.<br><br>After having finished a days work putting a raft trip in the water at a place called Diamond Creek on the Colorado River (western end of the Grand Canyon) we began our 75 mile trip back to the real world(?) about two hours after dark. The sky was crystal clear and the moon was full. We spent the next two hours intentionally driving slowly by moonlight only, up from the canyon through Peach Springs Wash. The moonlit canyon walls and desert foliage was beyond spectacular! The other memory is having spent several hours hiking in a Joshua Tree forest by moonlight. So easy to let your mind put you on a planet far, far away. The sights are still vivid in my mind these many years later. There are times when added light may just be an intrusion on the things that need to be seen.
