Supai sandstone
Supai sandstone
876 feet
No, it has already passed through the Grand Canyon.
Because it is downhill from North Canyon to Nankoweap Canyon.Water has a funny way of flowing downhill. The real answer is due to the uplift of the Colorado Plateau which is due to Plate Tectonics.
the actual answer is 2,800 feet. It was on my paper. Your Welcome! :)
The Vishnu Schist rock layer is at river level in North Canyon in the Grand Canyon. It is one of the oldest rock formations in the canyon and consists of metamorphic rocks that have been folded and twisted over millions of years.

In North Canyon, the rock layer at river level is typically composed of sedimentary rocks, often including sandstone, limestone, or shale, depending on the specific geological history of the area. These layers have been shaped by erosion and sediment deposition from the river over time. To determine the exact layer, geological maps or local studies would provide more precise information about the stratigraphy in that region.
The elevation of land surface above sea level has the least effect on the time needed for a river to form a canyon.
About 2,600 feet above sea level.
At it's deepest, the lowest area of the Grand Canyon is over 6,000ft below the canyon rim.
