It was all I expected and more. One of the most spectacular examples of erosion anywhere in the world, Grand Canyon is unmatched in the incomparable vistas it offers to visitors on the rim. The Canyon, incised by the Colorado River, is immense, averaging 4,000 feet deep for its entire 277 miles. It is 6,000 feet deep at its deepest point and 15 miles across at its widest. However, the significance of Grand Canyon is not limited to its geology.
It is home to numerous rare, endemic (found only at Grand Canyon), and specially protected (threatened/endangered) plant and animal species. Over 1,500 plant, 355 bird, 89 mammalian, 47 reptile, 9 amphibian, and 17 fish species are found in the park. (Source: National Park Service)
There is no one word or even group of words to describe the Canyon that is Grand. It's been said that no one forgets their first view of the canyon. I know, I won't. As you approach from the south through Arizona, there is nothing that suggests what lies ahead. I drove through relatively flat, wooded areas with a small mountain or butte here and there. The only reminders were the signs confirming that the canyon was ahead. I can only let the photos do the talking, and they don't begin to tell the story of a canyon 6 million years in the making. Some of the rock formations shown here are seen from different points of view as many as a mile or two apart. My comments will be minimal.
