The colors are beautiful--and constantly changing.
Here's another glimpse of the awesome beauty. I don't believe any of these photos actually shows the very bottom of the canyon. It's way deep, around a mile deep. Elevation at the rim is about 7,000 feet, so I was easily winded when I walked a little too far along the rim one day.
Obviously, it's impossible to grasp the grandeur from a few photos, but it's really something else.
One of my thoughts was, wouldn't it be a bummer to be bumping along in your covered wagon, on your way to California sometime a couple of centuries ago, and come across this! "OK, now what do we do!???"
Time for Plan B.
