A new map and age model for the middle Allegheny River, along with existing data for Glacial Lake Monongahela (GLM) test long-held views for when and where low divides were breached in the assembly of the modern Allegheny River and the respective roles of upstream glacial margin or downstream base level change in driving post-glacial river incision. Terrestrial cosmogenic nuclide (TCN) and optically-stimulated luminescence (OSL) data suggest reversal and assembly of the Allegheny River during a very early glacial advance.
