Three of the higher peaks of the Bernese Alps are visible -Jungfrau (4,158 m), Moench (4,089 m), and Eiger (3,970 m). To the east and south of the Jungfrau is the Aletsch Glacier, clearly marked by dark medial moraines extending along the glaciers length parallel to the valley axis.

Moraines are formed from rock and soil debris scoured along the sides of mountain glaciers that gradually accumulate in the middle of the glacier and are carried along the flow direction. Lake Brienz to the northwest is glacially carved.
