6 layer, supai sandstone
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.
Colorado river
The Grand Canyon is located on the North American tectonic plate. This massive canyon was formed by the erosion of the Colorado River cutting through layers of rock 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 Grand Canyon was primarily carved by the Colorado River. Over millions of years, the river's erosive power, combined with geological processes, shaped the canyon's intricate layers and formations. This ongoing erosion continues to influence the canyon's landscape today.
The Colorado River cut through layers of rock over millions of years to form the Grand Canyon. The process of erosion and the uplifting of the Colorado Plateau contributed to the formation of this iconic natural wonder.
The Colorado River first eroded through the Kaibab Limestone and the Toroweap Formation. These layers are part of the Grand Canyon's geological structure and were exposed as the river cut down through the rock over millions of years. The erosion of these layers contributed to the canyon's depth and distinctive features.
It is the Colorado River.
A canyon can be formed by a combination of erosion processes such as water flow, wind, and ice carving through the rock layers over millions of years. The process typically involves the gradual wearing down of the surface material, leading to the deepening and widening of the canyon through natural forces.
