Dreieckhorn

The Jungfrau-Aletsch protected area (officially Swiss Alps Jungfrau-Aletsch) is located in south-western Switzerland between the cantons of Berne and Valais. It is a mountainous region in the easternmost side of the Bernese Alps, containing the northern wall of Jungfrau and Eiger, and the largest glaciated area in western Eurasia, comprising the Aletsch Glacier. The Jungfrau-Aletsch protected area is the first World Natural Heritage site in the Alps; it was inscribed in 2001.

The Konkordiaplatz or Concordia Place (French: Place de la Concorde), is a flat area of snow and ice lying just to the south of the Jungfrau in the Bernese Alps in the Swiss canton of Valais. It is the junction of four large glaciers coming down from the Aletschfirn, the Jungfraufirn, the Ewigschneefäld and the Grüneggfirn. The main Aletsch Glacier originates from Konkordiaplatz. The Konkordiaplatz Charter was signed by the municipalities located in the Jungfrau-Aletsch Protected Area UNESCO World Heritage site, vowing to retain the aesthetic beauty of the region.

The Konkordia Hut (German: Konkordiahütte) is a mountain hut of the Swiss Alpine Club, located north of Fieschertal in the canton of Valais. The hut lies above Konkordiaplatz, the point of convergence of several glaciers in the great Aletsch Glacier system of the Bernese Alps. It is located at a height of 2,850 metres above sea level, at the foot of the Fülbärg.

The Sattelhorn is a mountain of the Bernese Alps, overlooking the Lötschenlücke in the canton of Valais. It lies west of the Aletschhorn, between the Lang Glacier and the Oberaletsch Glacier.

The Lötschenlücke (el. 3153 m.) is a high mountain pass of the Bernese Alps, connecting the Lötschental to the valley of the Aletsch Glacier in the canton of Valais. Both sides of the pass are covered by glaciers: the Langgletscher on the west and the Grosser Aletschfirn on the east. The Lötschenlücke lies between the Mittaghorn on the north and the Sattelhorn on the south. The closest settlement is Fafleralp (east of Blatten) in the Lötschental. There are no settlements in the valley of the Aletsch Glacier. Above the pass, at 3,240 m, lies the Hollandia Hut of the Swiss Alpine Club.

The Kranzberg (3,742 m) is a mountain of the Bernese Alps, overlooking the Aletsch Glacier in the Swiss canton of Valais, close to the border with the canton of Bern. Its massif separates two glaciers: the Grosser Aletschfirn and the Jungfraufirn, both part of the Aletsch Glacier. A prominent unnamed secondary summit (3,666 m) is located south-east of the main peak. Debris accumulating on both sides of the mountain form one of the two important supraglacial moraines of the Aletsch Glacier (see picture on the top right of the article).

The Hollandia Hut (German: Hollandiahütte) is a mountain hut of the Swiss Alpine Club, located east of Blatten in the canton of Valais. The hut lies at a height of 3,240 metres above sea level, just above the Lötschenlücke, the glacier pass connecting the Lötschental from the Aletsch Glacier. All accesses to the hut involve glacier crossing. The Hollandia Hut is a starting point for the ascents of the Ebnefluh, Mittaghorn, Aletschhorn, Sattelhorn, Gletscherhorn and Anungrat.

The Gletscherhorn (3,983 m) is a mountain of the Bernese Alps, located on the border between the Swiss cantons of Bern and Valais. It forms the eastern edge of the Lauterbrunnen Wall, south of the Jungfrau.

The Trugberg is a mountain in the Bernese Alps, located south of the Mönch in the canton of Valais, Switzerland. It is located above the Konkordiaplatz where the névé of the Jungfraufirn on the west side and the Ewigschneefeld on the east side converge to form the Aletsch Glacier. Debris accumulating on both sides of the mountain form one of the two important supraglacial moraines of the Aletsch Glacier. During their ascent of the Jungfrau in 1841, a group of explorers including Pierre Jean Édouard Desor and Louis Agassiz for a while thought that the Trugberg, hiding the Jungfrau from sight, was their destination. Eventually, they realized their error and decided to name the mountain Trugberg, meaning Deceitful Mountain.The Trugberg was first climbed 13 July 1871 by Dr. Emil Burckardt from Basel, with the two local guides Peter Egger and Peter Schlegel. The route they took was by the east flank.

The Ebnefluh, also known as the Äbeni Flue and the Ebenefluh, (3,962 m) is a mountain of the Bernese Alps, located on the border between the Swiss cantons of Bern and Valais. It lies towards the eastern end of the Lauterbrunnen Wall.

The Lang Glacier (German: Langgletscher) is a 6.6 km (4.1 mi) long glacier (2005) situated in the Bernese Alps in the canton of Valais in Switzerland. In 1973 it had an area of 10.1 km2 (3.9 sq mi).

The Rottalhorn (3,972 m) is a mountain of the Bernese Alps, located on the border between the Swiss cantons of Bern and Valais. It lies 600 m south of the Jungfrau, between the small valley of the Rottal and the Jungfraufirn (part of the Aletsch Glacier).
