Sedimentary and genetic evidence indicates that a paleo-Tennessee flowed into the Mobile Basin through the late Miocene, although alternate models propose other redirections of the river. We constrain the river course’s age by dating terraces near Pickwick, Tennessee, with cosmogenic<span>&nbsp;</span>²⁶Al/¹⁰Be isochron burial dating. We find that the river’s present path dates to at least the early Pliocene.</p></div></div> application/pdf 10.1086/719951 en University of Chicago Press The Pliocene-to-present course of the Tennessee River article
