A newly published book titled “The Topographic Map Mystery:Geology’s Unrecognized Paradigm Problem” discusses in considerable detail the problems geomorphologists have encountered when trying to explain topographic map drainage system and erosional landform evidence (such as is discussed on this website) and describes a new and fundamentally diffrent Cenozoic geology and glacial history paradigm which is able to explain the topographic map drainage system and erosional landform evidence (and which was developed from the evidence this website describes). The book is available from a variety of on-line booksellers in e-book, softcover, and hardcover editions (or the book author, Eric Clausen, will provide a pdf of the book to readers of this website who send him an e-mail message briefly describing their interest in this website and in reading the book–such email messages should be sent to eric2clausen@gmail.com). The following is a short excerpt from the book’s introduction.

Understanding United States Geological Survey (USGS) topographic map drainage system and erosional landform evidence is critical if North America’s glacial history (and middle and late Cenozoic geologic history) is to be understood, but the geological research community for decades has ignored that topographic map evidence and today has no clue as to what story the topographic map drainage system and erosional landform evidence is patiently waiting to tell. To modify a famous quote there are some things geology research community members know, there are some things geology research community members know they do not know, and there are some things geology research community members do not know that the geology research community does not know, and among those latter things is geology research community members do not know that the geology research community does not know what the well-mapped USGS topographic map drainage system and erosional landform evidence has to say.

The topographic map mystery is: does detailed topographic map drainage system and erosional landform evidence tell the Cenozoic geology and glacial history the geology research community describes or does that topographic map evidence tell a different Cenozoic geology and glacial history which someday will force the geology research community to rewrite many of its now commonly accepted Cenozoic geology and glacial history interpretations? This book illustrates examples of topographic map drainage system and erosional landform evidence the geology research community’s accepted Cenozoic geology and glacial history paradigm cannot satisfactorily explain and briefly describes a new and fundamentally different Cenozoic geology and glacial history paradigm which does explain that topographic map evidence.
