The rock layer at level 6 in Nankoweap Canyon is the Redwall Limestone, a prominent rock formation that is well exposed in this area. The Redwall Limestone is known for its distinctive red color and forms impressive cliffs along the canyon walls. Its position at level 6 indicates its relative depth within the geological sequence of the Grand Canyon region.
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.

water erodes a canyon by carrying sediment from the rock walls down the river
No, the Grand Canyon is not found in the Sonoran Desert
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.
Over the course of more than 17 million years, the Colorado River gradually eroded away sediment and rock to create a canyon.
