Publisher's Synopsis
Excerpt from The Pleistocene Deposits of Sankoty Head, Nantucket, and Their Fossils
That the cliff section shown at Sankoty Head has changed since the first mention of it by Desor and Cabot, is very certain. A'at that time and for many years following, the waves attacked the base of the clifi, gradually eating their way into it and causing a complete exposure of the beds from top to bottom. Since the time of the earliest observers there has come about, what may be considered a radical change. The beach, from the angle of the island near Siasconset, has gradually been extending northward so that for some years the base of the cliff has been protected from the erosive action of the waves. As a result of this protection 3. Large part of the surface of the cliff has now become clothed w1th vegetation. This covering is mainly of the coarse grass which so readily obtains a foothold when actual erosion is prevented. This change of the contour of the beaches has for years been given much attention. In this particular case its practical side is seen, for if active erosion should continue the lighthouse might become endangered. This protection makes harder the work of excavation and necessitates removing a large amount of loose material in order to reach portions which are in their original condition.
