If the structure was there before the canyon was created, it appears that parts of the Colorado River channel coincide with the axis of the anticline. A model study based on the concept of finite elements shows that a possible mechanism for the folding of the Muav Limestone is elastic rebound caused by relief from overburden pressure as material was eroded to form the canyon.
