J Harlen Bretz (“J” is his entire first name, not an abbreviation to be followed by a period) was the central figure in one of the most important controversies in the history of geology. In a series of papers in the s and s, Bretz formulated and defended the hypothesis that cataclysmic flooding during the last Ice Age produced the unusual landscape of the channeled scabland region of eastern Washington State. The controversy lasted until the s and s, by which time overwhelming field evidence combined with new understandings of flood mechanics, erosion, and sedimentation to convince most geologists that immense flooding was indeed the cause of the channeled scabland landscape.
Early Life.J Harlen Bretz was born on 2 September , in Saranac, Michigan, to Oliver and Rhoda Bretz, on the family farm. His father dabbled in farming but worked mainly in a store (variety and furniture) and in an undertaking business, both of which he owned. The young J Harlen Bretz (his original given name was Harley) had intense interests in amateur astronomy and in exploring the natural environment around the family farm, including
