A sunset on Grand Canyon
The grand canyon you will find in northern Arizonas Grand Canyon National Park.
It was cut into layer after layer of the clorful sedimentary rocks of the Colorado Plateau by the Colorado river,and is one of the worlds most spectactular landmarks.
The youngest rocks,at the top,were laid down by an inland sea som 260 million years ago and a journey down into the canyon peels away millions of years of geological history as the fifferent layers of rock-red stained limestone,sandstones,shales and mudstones,down to twisted granites and schists and the river bed,which was laid down more than 1,7 billion years ago-are revealed.
Not only the past of the Grand Canyon is unique,but also its share size.
Its 1,5 km deep at the most and stretches more than 16 km across at the most.
Its magnificent scenery makes it a true landmark of the worlds wonders to visit.
