English: View oft he valley of the Große Lauter in the village Bichishausen. The valley makes a loop to the right like an entrenched river does, leaving a rise or hill in the middle. The river has almost cut its loop, the height between the two closest parts is eroded down to mere few meters, the loop almost fully developed.
The rock bottom of the river, eroded in late Pleistocene time is now filled up with layers of sediments - humus for agriculture, clayey silt and solidified tufa (CaCO3) of varying thickness. The layer of tufa sediment was detected in the river bed for more than 3 km – which is 2 km behind the horizon. For a well identifiable bank of tufa see the photo: Image:Kalktuff-Wasserfall_Grosse-Lauter_Schwaebische-Alb.jpg. The valley is extremely broader than the actual small river is now. This refers to the long earlier epochs, during which the river valley was eroded. The gradual slope behind the row of trees on the right has a rocky fluvial terrace, which was formed by an earlier river bed of late pleistocene time.
