Mt. Haydn
The Grand Canyon extends about 440 km at a width of 29 km and reaches a maximum depth of 1600 m. This monument exposes rocks of 1700 million years including the last 500 million years of uninterrupted geology. That covers the entire time period of macroscopic life on our planet. The erosive forces of the Colorado River created this Canyon in just five million years. This became possible due to the constant uplift of the Colorado Plateau to a height of 3000 m. The uplift is a consequence of the tectonics and isostatic vertical displacements resulting from the orogenesis of the Rocky Mountains.
