The Grand Canyon was formed as the Colorado River slowly wore down the bedrock. That probably took millions of years though, said geologist and study co-author Michael Lamb of Caltech in Pasadena, Calif. Rapid gorge carving is a baffling example of how incising bedrock doesn’t take millions of years.
How long did the Grand Canyon take to form?
five to six million years
The Colorado River has been carving away rock for the past five to six million years. Remember, the oldest rocks in Grand Canyon are 1.8 billion years old. The canyon is much younger than the rocks through which it winds.

Sixty million years ago, the Rocky Mountains and the entire Colorado Plateau, which the Grand Canyon is part of, rose up from tectonic activity.

How many years does it take for a canyon to form?
Rivers carve into the land with their rushing waters, wearing away the land and over millions of years, a canyon is formed. Canyons like this one in New Zealand form over millions of years.

Was the Grand Canyon once an ocean?
The Vishnu rocks formed about 1.7 billion years ago when magma hardened and joined this region—once a volcanic ocean chain—to the North American continent.
