The Mogollon Rim marks the southern edge of the Colorado Plateau. This escarpment was not formed by a fault, but rather by the uniform erosion back from a monocline that formed over a fault. In a monocline, layers bend in one direction between layers of rock, kind of like a ramp. (see the picture to the right source:Dr. Judson L. Ahern).

The geological record of the Western Andean Escarpment (WARP) reveals episodes of uplift, erosion, volcanism and sedimentation.
