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.
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.

The Colorado River is within and it created the Grand Cayon.
