I guess I am surprised that these clay hills have not disappeared long ago. It would seem that one or two good rainfalls would wash away this pile of mud and leave nothing but the imbedded rocks behind. What is the case, however, is that the clay is extremely resistant to erosion because of overlaying much harder rocks. So you can see these clay hills even in areas that seem to get a substantial amount of rain.
