This informative book takes a comprehensive look at the subject of glacial geology in the Pleistocene Epoch, and is highly recommended for inclusion on the bookshelf of anyone with an interest in the subject. Preface: The Pleistocene epoch occupies a peculiarly important place in the time scale of geology, for it embraces the events of the latest million or more years in the history of the Earth and is therefore so recent that it bridges the gap between the geologic changes now in progress and the more remote past. When the work of the geologist is finished, wrote Gilbert, and his final comprehensive report written, the longest and most important chapter will be upon the latest and shortest of the geologic periods. The chapter will be longest because the exceptional fullness of the record of the latest period will enable him to set forth most completely its complex history. The changes of each period - its erosion, its sedimentation, and its metamorphism - obliterate part of the records of its predecessor and of all earlier periods, so that the order of our knowledge must continue to be, as it now is, the inverse order of their antiquity. This fact in itself furnishes an adequate reason for making the principal facts of the Pleistocene epoch compactly available, not only to geologists but also to ecologists, archeologists, geographers, and . others whose studies reach back into the prehistoric realm. In addition, the increased pace of research upon Pleistocene problems in general, and problems in glacial geology in particular, that has been evident during the last two decades has emphasized the necessity, in this field, of a summary that will be at once a reference to the data already established and a means of indicating the areas and problems in which further research is most needed. These are the principal objectives of the present volume. No one knows better than its author that it falls short of attaining them. Knowledge of the Pleistocene has grown to s
