The word “grand” is inadequate to describe the Grand Canyon’s South Rim in Arizona. Carved by the Colorado River and 1.7 billion years of erosion, it extends 277 miles. Although ten miles across, it requires a 250 mile drive around it. This view from Yavapai Point is the shallowest at 2,400 feet. The canyon is 7,800 feet deep at the North Rim. Nearby is the Yavapai Geology Museum where park rangers provide interesting facts using a scaled model of the canyon.
