"The earth's greatest gorge", the Grand Canyon, is located in northwestern Arizona. Its length is 217 miles, and its widest point is over 17 miles across. It is not surprising that it has been designated as one of the Seven Natural Wonders of the World.
The walls of the canyon are made of limestone, sandstone, lava, and other rocks. As the day passes, the rocks reflect different colors. Many tourists come to the Canyon just to watch the rocks change color.
Cottonwood and willow trees grow at the bottom of the Canyon. Many varieties of cactus grow here as well. The Canyon is also home to many animals, such as bobcats, coyotes, kangaroo rats, and deer.
About 4 million visitors come to the Grand Canyon each year. Seeing the Grand Canyon is always a breathtaking and unforgettable experience.
