The Grand Canyon.
Or as a sardonic friend of mine once said, upon first seeing it, "Well, it's a great canyon but I'm not sure it's a grand canyon."
It's still an awe-inspiring sight.
There are those who can't seem to get close enough to the rim. (Click on these pictures for a "closer view.")
But wait! There's more! As we were heading away from the Canyon, we spotted these two cow elk. There really are two. The lighter one has her head down.
And, in spite of all those signs in Northern Arizona that say "Watch for Elk" and I had never seen one, these two and several others were peacefully wandering very close to the road. Here's the initial shot.
