1The Grand Canyon, U.S.A

Of course one cannot talk about the power of Mother Nature without mentioning the mighty Grand Canyon. The Grand Canyon is characterized by near-horizontal sedimentary rocks lifted 1500 to 4000 metres above sea level.

The canyon’s formation can be traced back approximately 1,200 million years ago when 4000 metres of lava and sediment were deposited in the then marine environment. Approximately 725 million years ago, mountain building lifted and tilted these rock layers. The snowmelt-fed Colorado River that later flowed through the region carved out the canyon.
