The Grand Canyon

Grand Canyon National Park, in Arizona, comprises much of the immense Grand Canyon. The layered bands of red rock are known for their antiquity, as well as their robust ecosystems. The Canyon is a vast space with a scope for enjoying a host of views that are aesthetically pleasing. Popular viewing points include Mather Point, Yavapai Observation Station and architect Mary Colter´┐Żs Lookout Studio and her Desert View Watchtower. Lipan Point is another area of the canyon that is quite popular. It offers a view of the canyon as well as the Colorado River.

The three main types of sedimentary rocks that make up the Grand Canyon are sandstone, shale (or mudstone), and limestone.

The lowest level of the Grand Staircase is the Grand Canyon. The upper layers of the canyon are made of sedimentary rocks. The lower layers are made of metamorphic rocks, since they are exposed to higher magnitudes of heat and pressure. As compared to Bryce Canyon, which lies at the top of the staircase, the rocks are way older. In fact, the rock situated in the lowest layer, where the Colorado River flows, is 1.75 billion years old.
