Layered Depths of the Grand Canyon

Layered Depths of the Grand Canyon is an original illustration set in Grand Canyon South Rim, Arizona, USA. It lies in mid-latitudes, where the climate is cold semi-arid steppe.

Red and cream rock layers step down from a high plateau into an immense branching canyon. Broad flat-topped buttes repeat across the distance, a small stretch of river lies deep below, and sparse juniper and dry grass cling to the foreground rim.

Why do these immense canyon walls alternate between cliffs and gentler slopes?

The Colorado River cut downward through an uplifted plateau, exposing stacked sedimentary layers. Harder beds hold cliffs while softer beds retreat into slopes, so the same bands repeat across separate buttes and side canyons. Dry conditions leave these rock structures unusually clear; the depth, horizontal layering, and branching erosion identify the Grand Canyon landscape.
