From the bloggers at Road Less Traveled:
After driving through the red rock wonderland of the Vermillion Cliffs in northern Arizona, we found ourselves at 10,000-foot elevation on the Kaibab Plateau in beautiful pine forests.
This is the home of the Grand Canyon where the earth seems to have split apart, revealing the massive crimson hued jagged walls that rise up from the Colorado River thousands of feet below.
A huge region towards the middle of the chasm has been set aside as Grand Canyon National Park, and it has two entrances you can drive to, one on the north side of the canyon and one on the south side. At each of those spots you can wander along the rim and peer over the edge to look 6,000 feet down.
