Vertical Canyons

Because of the softness of underlying strata, erosional forces create almost vertical canyons in the fact of this formation. Deeper canyons are created when the overlying rock is fragmented or missing. I have seen the same type of formations with steep almost vertical canyons on a very small scale when I dig in sand that has been alternatively watered by rain and then dried. The particles of sand form the same types of layers and as you dig away the sand, miniature cliffs form that look very similar to these formations.
