The Grand Canyon
The Grand Canyon can be seen wending its way through Arizona in this UK-DMC2 image, acquired on 28 July 2015.
One of America's most famous landmarks, the Grand Canyon is 446 km long, and reaches depths of 1857 metres, with some portions almost 29 km wide.
The canyon was formed by the Colorado River, which carved out the shape of the canyon through millions of years of erosion. The river still stretches through the canyon today, continuing this process.
On the right side of the image, the blue area marks Lake Powell; an artificial river constructed on the Colorado River. This reservoir is currently the largest in the United States. From here, the river continues west-ward through the Grand Canyon and ultimately flows out into the Gulf of California.
The canyon is also a valuable source of study for geologists, as the canyon is so deep that its rock layers stretch back in time to present millions of years of well-preserved geological history.
The Grand Canyon was made a national monument of the United States in 1908 and a national park in 1919. It is now a very popular destination for tourism, affording visitors the chance to see an ancient natural formation and offering a range of activities including hiking and rafting.
