Interpretation of Topographic and Geologic Maps with Special Reference to Determination of Structure

INTERPRETATION OF TOPOGRAPHIC AND GEOLOGIC MAPS WITH SPECIAL REFERENCE TO DETERMINATION OF STRUCTURE, C.L. Dake and J. S. Brown, hardcover, 1925. BOOK CONDITION: very good. The text block is in near fine condition with no tears or marks and only one unfolded dog ear. There is no bookplate nor signature of a prior owner. This is not a remainder or library book. The brown cloth boards are in good condition (one bumped corner and “dusty” appearance because of some discoloring on front cover). 8 x 5 ½, 355 pages, 19 ounces. XX [From the preface] “The field of map interpretation is singularly lacking in anything approaching an adequate textbook, largely as a result of the fact that the numerous maps considered essential increase the cost of a text, almost prohibitively, The only agency suitably equipped to produce an adequately illustrated treatise on map interpretation is the Federal Government. Its one essay in this field, Professional Paper 60, " The Interpretation of Topographic Maps," has never been repeated. This book, though invaluable, contains little information on the reading of structure from contours, and still less on the interpretation of geologic maps. Lack of a suitable text has tended to limit the number and scope of courses in map interpretation and has in considerable measure deprived the teaching of elementary geology of one of its strongest assets, adequate map illustration. Listing illustrative maps in the general texts is admirable, but, unfortunately, the beginner without laboratory guidance sees only a small fraction of the significant features. A number of small but useful manuals on various phases of map interpretation have appeared, largely in the form of questions, but these manuals demand a skillful instructor to make them of most value. Map interpretation lends concreteness to general and structural geology and has been termed by one of our ablest teachers an “indoor field course". It may, in part, wisely replace field studies, with economy in time and money, and has the very real advantage that more of a region or a structure can be visualized at one time on a map than in the field. For these reasons the authors feel that there is a real place for a treatise of the type herewith presented. The material has been accumulated by the senior author through more than ten years of active teaching of map interpretation.”. …
