Erosion from The Colorado River that has occurred over millions of years.
Remember that episode of The Flintstones where they saw the Grand canyon on it was just this little trickle and wasn't a canyon at all? Nuff said.

Nowadays, many geologists are considering a theory that states there was a large,landlocked lake to the northeast of present-day Grand Canyon, about where the Petrified Forest now lives. The theory says that a natural dam on the west side of this giant lake collapsed, causing a massive flood that came roaring down the course of the Colorado River, and swept all the way to Black Canyon in the west. This flood caused a great deal of instant erosion, although the complete carving of the Canyon still took millions of years. It's one theory, anyway.

The Grand Canyon was eroded by the Colorado river over millions of years.
A little known fact is that the Colorado river is the only river in the world whose water does not end up in the sea!!!! Because the area is so dry, the water is diverted for irrigation purposes, and also into the towns and cities that are along the route. The Colorado's last drops evaporate in the Sonoran Desert, miles before the river reaches the Gulf of California.

The grand canyon has formed from vertical erosion, as it is the upper course of a river, the erosion will be downwards. Meaning that it will cut further and further into the earth, creating a valley. This has all happened over millions of years. Another type of erosion, is lateral erosion, at the lower course of a river, this is how ox-bow lakes and meanders are formed.

If the answer to your question is erosion, then why not the mighty Mississippi or Missouri or the Amazon or the Nile? Why only rivers in mountainous regions, and why in particular did erosion cause the Grand Canyon? Those individuals who in answering your question asked how anyone could believe in Noah's flood have to answer the above questions.
Yet, the question still remains, why are there only a few rivers in the world that have a Grand Canyon type of topography. Certainly, the answer describing the mountain lake blowing down in a massive torrent might appear reasonable. Yet, I believe what is more reasonable is that at the time of Noah's flood, the earth tectonics shifted dramatically, forcing the mountains upward in a rapid movement. The force of the water draining rapidly through the rapidly upthrust earth created instantaneous erosion in mountainous regions, especially where the soil deposits and earth were of a consistency that yielded to greater erosion than other geological formations.

Pour a drop of water on a rock.
Repeat about 60 trillion times. Voila!
Scientifically, it was formed by the Colorado River over the course of several hundred million years.

It was formed by melting glaciers. water formed a river which has eaten through the soft soils leaving the heavy rocks behind over many millions of years

The Colorado River carved out the canyon.
See link for info.
Have you been there?
I went to the South Rim, this past March.
FAN-TAS-TIC!
