S.153: Weiter im Nordosten ist erosiv in die älteren Schotter eingelagerter glazifluviatiler Schotter mit einem hohen Anteil an Schwarzwaldmaterial vorhanden (Möhlinerfeld-Schotter). An seiner Basis finden sich Blöcke aus Schwarzwaldmaterial. Er weist im Dach einen deutlichen Paläoboden auf.

Towards the north, another gravel unit (‘Möhlinerfeld-Schotter’) is found on top of Wallbach gravel with an erosive contact. This gravel is dominated by alpine material but contains boulders and pebbles of Black Forest origin. The boulder horizon [at the base = basale Blocklage] probably reflects the erosional remains of an intensively weathered till (‘Zeiningen-Till’) found in the southern part of the area, outcropping in the Bünten gravel pit. Petrography of this unit indicates an origin from the Wehra Valley, and indicates an advance of the Black Forest Glacier that reached all over Möhlinerfeld, and probably causing deformation of the two oldest gravel units mentioned above.
