What are some cool places in the Colorado, Utah, area that I can go to?

I am going on vacation to see four corners, mesa verdae, and the grand canyon. Any other interesting places I can check out?

1. Bryce & Glen Canyons & Grand Staircase, Utah!!! http://www.scenicbyway12.com/
2. Canyonlands National Park in UT - if you come into Colorado near Denver check out Red Rocks or the Great Sand Dunes National Park
3. In Colorado, you should go see the "Maroon Bells", near Aspen. They are a couple of beautiful mountain peaks that attract lots of attention. There are hiking trails there if you like to hike, or if you want, you can just bring a picnic since they also have picnic tables there. Anyway, I'm giving you a link to information about it in the source box. Have fun :-).
4. Sand Dunes, Dinosoar National Monument, Black Canyon of the Gunnison. Rocky Mountain State Park
5. I would definitely make time for Arches National Park: http://www.nps.gov/arch And there's a reason everyone is mentioning the Great Sand Dunes National Park in Colorado. It's amazing: http://www.colorado-springs-vacation.com/great-sand-dunes-national-park.html Have fun!
