One of the great natural wonders of the world is Arizona’s Grand Canyon of the Colorado River. The whole gorge is 217 miles long and, from rim to rim, 4 to 18 miles wide.
One of the most amazing things about it is that it was made by a river! Almost hidden between the canyon walls a mile below, the rushing waters of the Colorado River, with the help of many smaller rivers flowing into it, carved out this great chasm in the course of millions of years.
Even now, the ceaseless cutting continues to carve deeper into the canyon floor. Erosion from wind and rain have increased the size of the ever-widening, many-colored rock formations that resemble a fairyland of towering peaks and castles.
Color change with the shifting shadows and the changing light. The Grand Canyon became a national park in 1919. -Johnny Wonder
