Below comes between the two mountain ranges of a greywacke zone that is wider towards the east. The Unterinntal was substantially formed in the Ice Age. When the glaciers retreated at the end of the last ice age about 20,000 years ago, the valley with a powerful layer of gravel was filled. The Inn cut gradually into this one and forming the present-day broad glaciated valley. The remains of the original valley floor form the central mountain terraces on both sides.


The Lower Inn Valley is located in the transition zone between the drier inner alpine Talk Lima of the Upper Inn Valley and the wetter climate of the northern foothills of the Alps.
