Bryce Canyon is a canyon system found in Utah in the United States that has been formed by headward erosion of the Colorado Plateau at the origin of rivers and streams. It is known for its many spire-like structures called hoodoos, which generally consist of thick layers of relatively soft and easily eroded rocks, such as mudstones, overlain by thin layers of harder and more resistant rocks, such as sandstones or limestones. Hoodoos attain their characteristic shapes because this protective cover of resistant rocks shields the underlying layers from the elements, while the surrounding rocks are subjected to frost weathering and river erosion.
