Clearly different from the aforementioned ridges is the eastern slope of the Long Rhön, which forms the transition zone from the High Rhön to the muschelkalk region of the Mellrichstadt Gäu (Mellrichstädter Gäu), the eastern part of the Werra Gäu Plateaux. Individual domes rise from the descending Triassic beds east of the solid basalt covering of the Long Rhön in the interfluvials of the tributaries of the Franconian Saale between Brend and Streu, notably the Gangolfsberg () and the Rother Kuppe (). This landscape bears a clear resemblance to the Kuppen Rhön.
