In this paper we demonstrate that rock sections, settling tank experiments, fossil reevaluations, and paradigm changes have been the basis for producing several different and conflicting theories concerning the origin of interbedded sandstone and shale strata known as the Haymond flysch. We show that when new models arise, old geological explanations may still remain viable. Debate and uncertainty ultimately prevail and this is perhaps the way it ought to be, since no one can observe ancient origins.
