Tuma (geography)
Tumas (plural feminine, sursilvan for "hill") denote the distinctive and landscape-defining earthfills in the area of Domat / Ems in the Chur Rhine Valley in the canton of Graubünden .
The total of twelve tumas originated in all probability from the fall energies of the Flims landslide , with whole packages being shipped. The fact that the Tumas are not erosion forms of the Rhine can be seen from the fact that cones are not a fluvial form of erosion and above all because the group stands like a bar at right angles to the direction of flow.
In addition, erosion does not explain the transport of the Vorderrheinischen material to Pardisla in Domleschg , i.e. along the Hinterrhein upstream.
Outside this region, elevations of this type are referred to as toma hills .
