It was breath-taking. Simply awe-inspiring. Warning, there are a ton of pictures below. I couldn't choose any to leave out.
One last thing about the Grand Canyon... If you ever go, please don't sacrifice your safety for a good picture. I can't tell you how many people I saw climbing over barricades and stepping way-too-close to the edge just to get a good picture. It was so scary to watch.
I also looked it up. 12 people accidentally die each year at the Grand Canyon while trying to get a good picture. Don't be that person - the picture is so not worth it.
