Especially in this direction snow accumulated on the shaded and leeward slopes of the summit plateau to form short cirque glaciers that made the sides of these funnel-shaped depressions.

There are still tarns in some of these old cirques, partly a result of the anthropogenic elevation of the low-side lip of the cirque, such as the formed as glacial lake behind a glacial moraine.

Since the downfaulting of the Upper Rhine Graben during the Eocene epoch, the two shoulders on either side have been uplifted: the Black Forest to the east and the Vosges to the west.

It is bounded by the Rhine valley to the west and south.Tectonically the range forms a lifted fault block, which rises prominently in the west from the Upper Rhine Plain, whilst seen from the east it has the appearance of a heavily forested plateau.The natural regions of the Black Forest are separated by various features: Geomorphologically, the main division is between the gentle eastern slopes with their mostly rounded hills and broad plateaux (so-called Danubian relief, especially prominent in the north and east on the Bunter Sandstone) and the deeply incised, steeply falling terrain in the west that drops into the Upper Rhine Graben; the so-called Valley Black Forest () with its Rhenanian relief.Large areas of the eastern Black Forest, the lowest layer of the South German Scarplands composed of Bunter Sandstone, are covered by seemingly endless coniferous forest with their island clearings.The exposed basement in the west, predominantly made up of metamorphic rocks and granites, was, despite its rugged topography, easier to settle and appears much more open and inviting today with its varied meadow valleys.
