to the northeast, the Reuss-Aare Glacier combined with the Rhine glacier. This extended north beyond the present-day River Danube to the area of the Swabian Jura. In Bavaria, the Riss moraines form a little subdivided countryside without bogs and lakes, where they are not covered by the younger deposits of the Würm glaciation. The gravels associated with the Riss moraines form the present high terraces of the Danube tributaries. During the Riss, the Salzach and Dachstein glaciers were somewhat smaller than during the Günz and Mindel glaciations, the latter extending in each case to the Hausruck and Kobernauß Forest ridge (subalpine molasse).
