A newly published book titled “The Topographic Map Mystery:Geology’s Unrecognized Paradigm Problem: Revised Edition” 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 different 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 including Barnes and Noble at https://www.barnesandnoble.com/w/the-topographic-map-mystery-eric-clausen/1142942193 in softcover, and hardcover editions. The following is a short excerpt from the book’s back cover.
“Most drainage systems and erosional landform features as mapped on United States Geological Survey topographic maps represent anomalous evidence which the accepted Cenozoic geology and glacial history paradigm has never satisfactorily explained and which the geology research community has almost always ignored. These feature blanket most continental land areas and include river and stream valleys, drainage divides, mountain passes, through valleys (valleys crossing drainage divides), canyons cut across mountain ranges, water gaps, wind gaps, abrupt river and stream direction changes, barbed tributaries, erosional escarpments and many other similar features. How can the geology research community claim to understand Cenozoic geology and glacial history when gelogists have never determined what the well-mapped topographic map drainage system and erosional landform evidence has to say?”
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. 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.

What topographic evidence warrants the inference from the increased water flow to a larger glacier?
The accepted consensus science arrived at a three-mile-high glacier from the floral and faunal evidence. That evidence indicated a more equable climate, which was then explained by the height required to split the jet stream.
