The group south of the Susten Pass forms the dividing range between the head waters of the Aare (west) from those of the Reuss.

This group forms a complex mass including four considerable ridges and attains its greatest height at the Dammastock and the Galenstock.

The lower part of the Göschenental is bounded on the south by a range running west to east diverging from the ridge between the Dammastock and the Galenstock.

[1] On the north side of the Susten Pass the ranges are lower and, except the highest mountains on the south, free of glaciers.

From the Grassen, tripoint border between the cantons of Bern, Obwalden and Uri, a small range diverges from the main watershed and runs from west to east and culminates at the Gross Spannort.
