A Grand Spectacle

A canyon is a deep steep-sided valley with a river running through it. The Grand Canyon in Arizona, USA is up to 1615 m deep, 6 to 20 km wide and more than 350 km long. Scientists say this great gash in the earth was caused entirely by the wearing down of rock by the Colorado River. Twelve major layers of rock are visible from the rim of the canyon. The bottom layer is made of black heavy rock estimated to be more than 2000 million years old. Halfway down there is a grey-blue limestone belt which is about 335 million years old. Near the top there are yellowish limestone layers which because of the number of fossils of marine snails and corals embedded in them are thought to have been laid down in warm seas.
The Grand Canyon is one of Nature's most awe-inspiring creations.
