Grand Canyon, AZNational Park |
Carved out by
the Colorado River, the Grand Canyon, nearly 1,500 metres deep, is the
most spectacular gorge in the world. Located in the state of Arizona,
it cuts across the Grand Canyon National Park. Its horizontal strata retrace
the geological history of the past 2 billion years. Prehistoric traces
also remain of human adaptation to a particularly harsh environment.
