Understanding drainage system and erosional landforms origins is critical if geologists want to properly describe North America's Cenozoic geology and glacial history and United States Geologic Survey topographic maps provide well-mapped but mostly ignored and unexplained or poorly explained drainage system and erosional landform evidence. The Topographic Map Mystery: Geology's Unrecognized Paradigm Problem illustrates dozens of examples of unexplained and poorly explained topographic map drainage system and erosional landform features and explores what that mysterious map evidence is patiently waiting to say. Does the topographic map drainage system and erosional landform evidence support the geology research community's frequently told Cenozoic geology and glacial history story or will the topographic map drainage system and erosional landform evidence-when finally understood-force the geology research community to completely rewrite its Cenozoic geology and glacial history?
