We illustrate one complete cycle of duration 2*Phi, which includes one uplifting and one quiescent period of time (duration of a cycle). It thus covers a time span of 1 Myr, from 3.80 Myr to 4.80 Myr in the model evolution. The first period is marked by no tectonic activity. In the first part, we can observe the formation of an indurated layer at the water table level.
