This compelling landscape is composed of a vast array of unusual shapes and brilliant colors. In daylight, the Grand Canyon of Arizona takes on a glimmering, mystical glow. As evening begins to fall, the colors of the sunset are reflected in the rocks. Yet no matter what you have read or heard about the Grand Canyon Tour, at first sight, you will surely be overwhelmed.
President Theodore Roosevelt was a major proponent of conservation of the Grand Canyon area, and visited on numerous occasions to hunt and enjoy the scenery.
Although millions of visitors take the Grand Canyon Tour each year, everyone comes with a different purpose. Some are fascinated by the formation of the rocks. Others are interested in the human element, and seek to explore the history of the people who have lived in this region. Some visitors want to study the unique plants and animals of the southwestern desert. However, once you take the Grand Canyon Tour, you will understand that all of these factors are interrelated.
Did you know that? The Grand Canyon, created by the Colorado River over 6 million years, is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 24 kilometers), and attains a depth of more than a mile (1.6 km). Nearly two billion years of the Earth's history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.
