Dixie National Forest, Utah Scenic Byway 12 on Flickr.

Via Flickr:
This is the western entrance on to Red Canyon, Utah on Scenic Byway 12–about 9 miles outside of Bryce Canyon National Park. The byway slices right through incredibly red canyon walls, and staying on the road as you gawk at the red rock rising on all sides is a challenge. Luckily, the canyon isn’t that big. ;) This is a shot at sunset, with the red light hitting the red walls, creating almost unbelievable red hues.
