The Later Stages of the Cycle of Erosion

Published online by Cambridge University Press:  01 May 2009

Extract

The establishment, toward the end of the last century, of the fruitful conception of the “ cycle of erosion ” carried with it into general currency certain ideas which rest on no real foundation. Although few, nowadays, would be so rash as to doubt the validity of the cycle idea or to question its value as a principle in geology, few can demonstrate any truth in the accepted pictures of the later stages of the cycle. Geographical old age and peneplanation rest on nothing but pure deduction by a few great masters of geography and geology and a blind acquiescence by the rest of us. I say blind advisedly, because only blindness could prevent us from seeing some serious inconsistencies in the picture which have not been generally noticed. These inconsistencies have become increasingly evident in the last ten years. It is time to recognize them.
