GEOGRAPHY ~ "The Grand Canyon"

Another stop on the "The Race Across America" for Geronimo Stilton was "The Grand Canyon."  Pages 68 and 69 of the novel, of the same name, tells readers "the Grand Canyon is a World Heritage Site in the state of Arizona.  It is considered one of the wonders of the world.  The canyon is a huge crack in a rock that averages 4,000 feet deep for its entire 277 miles.  It is 6,000 feet deep at its deepest point and 15 miles wide at its widest point."

The Grand Canyon

"The canyon was formed by the path of the Colorado River over the past five or six million years.  Over time, the canyon's walls grew wider and wider from summer thunderstorms and winter snowmelts.

"The Colorado River cuts through the Grand Canyon.  It begins in Rocky Mountain National Park, and flows approximately 1,450 miles to the Gulf of California in Mexico.  Its waters change color from red to blue to green, depending on weather conditions and the different sediments in the riverbed."
