The Grand Canyon is the largest known rift in the world. The canyon is a steep-sided gorge that was made by erosion from the Colorado River in northern Arizona. It is because of heavy mineral deposits that the canyon is bright red, brown and orange in color.

This canyon is a part of the large Grand Canyon National Park designated by former president Theodore Roosevelt. The park is almost 277 miles long and varies from 4 to 18 miles wide. The canyons are the main point of attraction in the nation park. Theodore Roosevelt used to come to the national park for relaxation and hunting.

Science shows that the canyons were carved out by the Colorado River some six million years ago with the deepest canyon depth being of over one mile. It is said that the river started cutting layers of rocks from the west initially and gradually moved to the east. The area was inhabited by Native Americans who lived within the caves. The Grand Canyon was considered a holy place for many pilgrims. The first European to explore this part of the world was Garcia Lopez de Cardenas who arrived from Spain in 1540. During the year 1869, Major John Wesley Powell made the first recorded journey down the Green and Colorado rivers through the Grand Canyon.

Some of the best adventures that a tourist can indulge in are river rafting, helicopter tours and other guided tours via land. Visitors can stay in the upscale Grand Canyon hotels and lodges to make the journey even more memorable.

    You stated that the Grand Canyon is the largest known rift in the world, which may be misleading without the following information from Wikipedia:
    “It is not the deepest canyon in the world (Kali Gandaki Gorge in Nepal is far deeper), nor the widest (Capertee Valley in Australia is about 0.6 mi/1 km wider and longer than Grand Canyon); however, the Grand Canyon is known for its visually overwhelming size and its intricate and colorful landscape.”

    Hi I’m Maddie Hahn from Explorer Middle School in Phoenix, AZ. I’m working on a science project about canyons and was wondering if you could answer some questions for me.
