Professor Strahler (Geomorphology, Columbia) assures the reader of his accessible book that he will learn much about the processes of geology which create landscape features while studying Cape Cod in particular, from the Ice Age to the present. The Cape originated in the Pleistocene Epoch, ""a relatively insignificant fragment of geological time which began about one million years ago and ended about ten thousand years ago,"" Wisconsin (late) stage. It has been worked on since by wind and wave and tide. By way of explaining how the features of the Cape came to be and are being processed, Professor Strahler easily plays out such geological terms as moraine, outwash plains, ice block lakes or kettles, scarf and swash and podzol (ash-soil). A solid addition to Cape study in line with the National Seashore programs and interest.
