Trugberg

The Mönchsjoch Hut (German: Mönchsjochhütte) is a mountain hut located in the Bernese Alps in the canton of Valais in Switzerland. At an altitude of 3,658 metres (12,001 ft) it is the highest staffed hut in Switzerland. The hut lies just above the Obers Mönchsjoch (3,627 m), between Mönch and Trugberg, on the upper Aletsch Glacier. It is used for the ascents of Jungfrau, Mönch and other peaks of the region.

The Bergli Hut (German: Berglihütte or Bärglihütte) is a mountain hut of the Swiss Alpine Club, located south of Grindelwald in the canton of Bern. It lies at a height of 3,299 metres above sea level on a rocky outcrop of the Eismeer, the glacier at the eastern foot of the Eiger and the Mönch. The border with the canton of Valais runs 500 metres south of the hut. The hut is set in a remote area and is accessible only to mountaineers as all accesses involve glacier crossing. The shortest access is from the Jungfraujoch train station.

The Mönch (German pronunciation: [ˈmœnç] , German: "monk") at 4,110 metres (13,480 ft) is a mountain in the Bernese Alps, in Switzerland. Together with the Eiger and the Jungfrau, it forms a highly recognisable group of mountains, visible from far away. The Mönch lies on the border between the cantons of Valais and Bern, and forms part of a mountain ridge between the Jungfrau and Jungfraujoch to the west, and the Eiger to the east. It is west of Mönchsjoch, a pass at 3,650 metres (11,980 ft), Mönchsjoch Hut, and north of the Jungfraufirn and Ewigschneefäld, two affluents of the Great Aletsch Glacier. The north side of the Mönch forms a step wall above the Lauterbrunnen valley. The Jungfrau railway tunnel runs right under the summit, at an elevation of approximately 3,300 metres (10,830 ft). The summit was first climbed on record on 15 August 1857 by Christian Almer, Christian Kaufmann (1831-1861), Ulrich Kaufmann and Sigismund Porges.

Eismeer railway station (German for Ice Sea) is an underground railway station bored into the mountain Eiger on the Jungfrau Railway, which runs to the Jungfraujoch from Kleine Scheidegg. It lies at an altitude of 3,159 metres above sea level, which makes it the second highest railway station in Europe. Located just behind the south-east face of the Eiger, the station's principal purpose is to allow passengers to observe the view of the glacier Ischmeer (lit.: Ice Sea, formerly called Grindelwald-Fiescher Glacier). To that end, uphill trains stop at the station for five minutes.The station opened on 25 July 1905, with the extension of the Jungfraubahn from its previous terminus at Eigerwand station. The building of the line this far had depleted the railway company's finances, and for the next seven years, Eismeer was to remain the upper terminus. After further fund-raising and an extended construction period, the line was extended to Jungfraujoch station in 1912 and Eismeer became an intermediate stop.The station also enables access of the Mittellegi Hut via a tunnel that leads out onto the Challifirn glacier. As a consequence, it is also a frequent starting point for ascents of the Eiger via the Mittellegi Ridge.Administratively, the station is in the municipality of Grindelwald in the canton of Bern.The following passenger trains operate:

The Sphinx Observatory is an astronomical observatory located above the Jungfraujoch in Switzerland. It is named after the Sphinx, a rocky summit on which it is located. At 3,571 m (11,716 ft) above mean sea level, it is one of the highest observatories in the world. Accessible to the public, it is also the second highest observation deck in Switzerland. The mountain top has been tunneled to fit an elevator which ascends to the observatory from the Jungfraujoch railway station, the highest such train station in Europe. The building is located on the Valais side of the border, only a few metres from the canton of Bern, although it is accessed via the Jungfrau Railway from the Bernese Oberland. The open viewing deck accessible to the public is adjacent to the observatory. It offers views of the Jungfrau, Mönch, and Eiger peaks, all within a few kilometers.

The Eiger (German pronunciation: [ˈaɪ̯ɡɐ] ) is a 3,967-metre (13,015 ft) mountain of the Bernese Alps, overlooking Grindelwald and Lauterbrunnen in the Bernese Oberland of Switzerland, just north of the main watershed and border with Valais. It is the easternmost peak of a ridge crest that extends across the Mönch to the Jungfrau at 4,158 m (13,642 ft), constituting one of the most emblematic sights of the Swiss Alps. While the northern side of the mountain rises more than 3,000 m (10,000 ft) above the two valleys of Grindelwald and Lauterbrunnen, the southern side faces the large glaciers of the Jungfrau-Aletsch area, the most glaciated region in the Alps. The most notable feature of the Eiger is its nearly 1,800-metre-high (5,900 ft) north face of rock and ice, named Eiger-Nordwand, Eigerwand or just Nordwand, which is the biggest north face in the Alps. This huge face towers over the resort of Kleine Scheidegg at its base, on the eponymous pass connecting the two valleys. The first ascent of the Eiger was made by Swiss guides Christian Almer and Peter Bohren and Irishman Charles Barrington, who climbed the west flank on August 11, 1858. The north face, the "last problem" of the Alps, considered amongst the most challenging and dangerous ascents, was first climbed in 1938 by an Austrian-German expedition. The Eiger has been highly publicized for the many tragedies involving climbing expeditions. Since 1935, at least 64 climbers have died attempting the north face, earning it the German nickname Mordwand, literally "murder(ous) wall"—a pun on its correct title of Nordwand (North Wall).Although the summit of the Eiger can be reached by experienced climbers only, a railway tunnel runs inside the mountain, and two internal stations provide easy access to viewing-windows carved into the rock face. They are both part of the Jungfrau Railway line, running from Kleine Scheidegg to the Jungfraujoch, between the Mönch and the Jungfrau, at the highest railway station in Europe. The two stations within the Eiger are Eigerwand (behind the north face) and Eismeer (behind the south face), at around 3,000 metres. The Eigerwand station has not been regularly served since 2016.

Jungfraujoch is an underground railway station situated near the Jungfraujoch, in the canton of Valais, a few metres from the border with the canton of Bern. At 3,454 metres (11,332 ft) above sea level, it is the terminus of the Jungfrau Railway and the highest railway station in Switzerland and Europe. The Jungfrau Railway runs from Kleine Scheidegg in the Bernese Oberland, through the Jungfrau Tunnel (inside the Eiger and Mönch) and crosses the border between the two cantons shortly before the terminus. The station is located east of the Jungfraujoch, less than 300 metres away, below the Sphinx ridge. The Jungfraujoch itself is a snow saddle constituting the lowest point of the ridge between the Jungfrau and the Mönch. A complex of tunnels connects the railway station to the Top of Europe building, overlooking the Aletsch Glacier on the south side, and an elevator to the summit of the Sphinx, the peak overlooking the saddle from the east. At the Sphinx are enclosed and open viewing platforms, with views over both sides of the Jungfraujoch and the surrounding peaks. A scientific observatory, the Sphinx Observatory, is also located here.Also accessed via the tunnels is the Ice Palace, a series of ice caverns beneath the glacier, and the Alpine Sensation, which presents a display on the tourist development of the Alps and the history of the Jungfrau Railway.Administratively, the station is situated in the municipality of Fieschertal in the canton of Valais, albeit very close to the border with the municipality of Lauterbrunnen in the canton of Bern. The cantonal border follows the watershed across the Jungfraujoch above the station.The station is served by trains of the Jungfrau railway, which run from Kleine Scheidegg, where they connect with services from Interlaken, Lauterbrunnen, Wengen and Grindelwald via the Bernese Oberland railway and the Wengernalp railway. The following passenger trains operate:

The Jungfraujoch (German: lit. "maiden saddle") is a saddle connecting two major 4000ers of the Bernese Alps: the Jungfrau and the Mönch. It lies at an elevation of 3,463 metres (11,362 ft) above sea level and is directly overlooked by the rocky prominence of the Sphinx. The Jungfraujoch is a glacier saddle, on the upper snows of the Aletsch Glacier, and part of the Jungfrau-Aletsch area, situated on the boundary between the cantons of Bern and Valais, halfway between Interlaken and Fiesch. Since 1912, the Jungfraujoch has been accessible to tourists by the Jungfrau line, a railway from Interlaken and Kleine Scheidegg, running partly underground through a tunnel through the Eiger and Mönch. The Jungfraujoch railway station, at an elevation of 3,454 metres (11,332 ft) is the highest in Europe. It lies east of the saddle, below the Sphinx station, and is connected to the Top of Europe building, which includes several panoramic restaurants, shops, exhibitions, and a post office. Several tunnels lead outside, where secured hiking trails on the crevassed glacier can be followed, in particular to the Mönchsjoch Hut. The normal route to the Jungfrau and Mönch starts from there. The Sphinx Observatory, one of the highest astronomical observatories in the world, provides an additional viewing platform at a height of 3,572 metres (11,719 ft), the second-highest in Switzerland. It can be reached by an elevator from the Jungfraujoch. The observatory houses one of the Global Atmosphere Watch's atmospheric research stations. The Jungfraujoch radio relay station, which is not accessible to the public, is installed west of the Jungfraujoch, on the Jungfrau ridge. It is Europe's highest radio relay station.

Eigerwand is a currently disused underground railway station on the Jungfrau railway, which runs to the Jungfraujoch from Kleine Scheidegg. The station is situated just behind the north wall of the Eiger, and its principal purpose was to allow passengers to observe the view through a series of windows carved into the rock face. Trains to Jungfraujoch used to stop at the station for five minutes.However, since late 2016, after the introduction of new, faster, rolling stock, the Jungfraubahn no longer stops here. Indeed, much of the 2017 publicity material fails to acknowledge that this viewpoint station ever existed. The station opened on 28 June 1903, with the extension of the Jungfraubahn from its previous temporary terminus at Rotstock station. After further construction, the line was extended to Eismeer station on 25 July 1905, and Eigerwand became an intermediate stop.Administratively, the station is in the municipality of Grindelwald in the canton of Bern. However, the only access to the station other than by train is a door in the sheer face of the mountain. This has, on occasion, been used to rescue mountaineers stranded on the mountain, most famously during the 1936 Eiger north face climbing disaster. It features in this capacity in the film The Eiger Sanction. It also lies right next to the Stollenloch, an exit and unofficial stop which is typically used by mountaineers to bypass the lower approach of the North Face.Prior to its closure, the following passenger trains operated:

The Mittellegi Hut (German: Mittellegihütte) (3,355 m) is a mountain hut in the Swiss Alps, located on the Mittellegi ridge of the Eiger above Grindelwald. It is the highest mountain hut in the canton of Bern. Its construction was funded by Maki Yūkō, a Japanese climber, in 1924 as a memorial of his world first climb to the Eiger.

The Eiger Glacier (German: Eigergletscher) is a glacier situated on the north-west side of the Eiger in the Bernese Alps of Switzerland. The glacier is within the municipality of Lauterbrunnen in the canton of Bern.In 1973 it had an area of 2.13 km2 (0.82 sq mi), and a length of 2.6 km (1.6 mi). By 2005 its length had reduced to 2.5 km.

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).
