the community herbertingen with its rolling hills and wide valleys is located on the northern edge of upper swabia. the landscape is formed by the ice masses and the meltwater of the rhine glacier, which has been advancing from the alps to upper swabia for more than 2 million years during several ice ages. the valleys of the danube, schwarzach and krähenbach were carved into the molasse layers, colorful marls and glimmering fine sands, which form the core of the long hills between the valleys and their subsoil. the glacier of the penultimate, the crack ice age (200,000 to 130,000 years before today) crossed the territory of the community with repeated advances and left deep valleys and small lakes between steep hills with fat ground moraine on hills and slopes for agriculture and gravel for the gravel pits.
