It was virtually identical to today's version. Erosion and weathering is a very slow process.
Yes, the Grand Canyon as we know it today would look very much like the Grand Canyon of 17 million years ago.
About 17 million years ago. Actually the Grand Canyon was built 2 billion years ago!
The grand canyon was formed thousands of years ago it was formed by rushing waters that carved out the mile deep canyon
Yes, the Grand Canyon was once filled with water millions of years ago.
The Grand Canyon is millions of years old. A mere 5000 years ago, it looked just as it does now, without the man-made improvements. In 5000 years, there would have been minimal further erosion of the river bed, but you would scarcely notice this in such an immense canyon.
5 million years ago.
The Anasazi.
Yes, the Grand Canyon was once submerged under an ocean millions of years ago.
About 17 million years ago.

The Grand Canyon has not erupted for millions of years. The most recent volcanic activity in the area was about 1.2 million years ago. Since then, the erosion from the Colorado River has been the primary force shaping the canyon.
The Grand Canyon rocks formed from 2 Billion years ago to the present. The Grand Canyon is an excellent place for studying geology and the history of the earth.
