The Jungfrau ( ), at is one of the main summits of the Bernese Alps, located between the southern canton of Bern and the northern canton of Valais, halfway between Interlaken and Fiesch. Together with the Eiger and Mönch, the Jungfrau forms a massive wall of mountains overlooking the Bernese Oberland and the Swiss Plateau, one of the most distinctive sights of the Swiss Alps.

The summit was first reached on 3 August 1811, by the Meyer brothers of Aarau and two chamois hunters from Valais. The ascent followed a long expedition over the glaciers and high passes of the Bernese Alps. It was not until 1865 that a more direct route on the northern side was opened.

The construction of the Jungfrau Railway in the early 20th century, which connects Kleine Scheidegg to the Jungfraujoch, the saddle between the Mönch and the Jungfrau, made the area one of the most-visited places in the Alps. Along with the Aletsch Glacier to the south, the Jungfrau is part of the Jungfrau-Aletsch area, which was declared a World Heritage Site in 2001.

Etymology

The name (), which refers to the highest of the three prominent mountains overlooking the Interlaken region, along with the Mönch () and the Eiger (), is most likely derived from the name Jungfrauenberg given to Wengernalp, the alpine meadow directly facing the huge northern side of the Jungfrau, across the Trummelbach gorge. Wengernalp was so named for the nuns of Interlaken Monastery, its historical owner. Contrary to popular belief, the name did not originate from the appearance of the snow-covered mountain, the latter looking like a veiled woman.

The "virgin" peak was heavily romanticized as "goddess" or "priestess" in late 18th to 19th century Romanticism. Its summit, considered inaccessible, remained untouched until the 19th century. After the first ascent in 1811 by Swiss alpinist Johann Rudolf Meyer, the peak was jokingly referred to as "Mme Meyer" (Mrs. Meyer).

Geographic setting

Politically, the Jungfrau (and its massif) is split between the municipalities of Lauterbrunnen (canton of Bern) and Fieschertal (canton of Valais). It is the third-highest mountain of the Bernese Alps after the nearby Finsteraarhorn to the east and Aletschhorn to the south, respectively. But from Lake Thun, and the greater part of the canton of Bern, it is the most conspicuous and the nearest of the Bernese Oberland peaks; with a height difference of between the summit and the town of Interlaken. This, and the extreme steepness of the north face, secured for it an early reputation for inaccessibility.

The Jungfrau is the highest point of a gigantic wall dominating the valleys of Lauterbrunnen and Grindelwald. The wall is formed by the alignment of some of the biggest north faces in the Alps, with the Mönch () and Eiger () to the northeast of the Jungfrau, and overlooks the valleys to its west and north by a height of up to . The Jungfrau is approximately from the Eiger; with the summit of the Mönch between the two mountains, from the Jungfrau. The Jungfraujoch is the saddle between the Jungfrau and the Mönch and the Eigerjoch is the saddle between the Mönch and the Eiger.

The wall is extended to the general southwest by over a distance of about as far as to the Tschingelhoren () with the Lauterbrunnen Wall on its second half overlooking the beginning of the Lauterbrunnen Valley to the north.

From the Eiger onwards to the northeast follows another high Alpine ridge over about –however broken three times by very steep and up to deep gorges draining highest Alpine glaciers (Ischmeer/Ober Ischmeer, Grindelwald, Rosenlouwi Glaciers)–as far as the Wellhorn ().

From the Mönch to the east starts a third impressive ridge with the Gross Fiescherhorn () after about with its impressive, northern Fiescher Wall below it. The highest Alpine ridge divides here into two, one leading south and the other roughly to the west as far as the Grimsel Pass in a distance of about as the crows fly.

The difference of altitude between the deep valley of Lauterbrunnen () and the summit is particularly visible from the area of Mürren. From the valley floor, west of the massif, the altitude gain is more than for a horizontal distance of .

The landscapes around the Jungfrau are extremely contrasted. In contrast to the vertiginous precipices of its northwest, the mountain's southeastern side emerges from the upper snows of the Jungfraufirn, one of the main feeders of the Aletsch Glacier, at around . The valley of Aletsch on the southeast is completely uninhabited, and is surrounded by neighboring valleys with similar landscapes. The area as a whole constitutes the largest glaciated area not just in the Alps, but in Europe as well.

Climbing history

In 1811, the brothers Johann Rudolf (1768–1825) and Hieronymus Meyer, sons of Johann Rudolf Meyer (1739–1813), the head of a rich merchant family of Aarau, along with several servants and a porter picked up at Guttannen, first reached the Valais by way of the Grimsel, and crossed the Beich Pass, a glacier pass over the Oberaletsch Glacier, to the head of the Lötschen valley. There, they added two local chamois hunters, Alois Volken and Joseph Bortis, to their party and traversed the Lötschenlücke before reaching the Aletschfirn (the west branch of the Aletsch Glacier), where they established the base camp, north of the Aletschhorn. After the Guttannen porter was sent back alone over the Lötschenlücke, the party finally reached the summit of the Jungfrau by the Rottalsattel on 3 August. They then recrossed the two passes named to their point of departure in Valais, and went home again over the Grimsel.

The journey was a most extraordinary one for the time, and some persons threw doubts at its complete success. To settle these, another expedition was undertaken in 1812. In this the two sons, Rudolf (1791–1833) and Gottlieb (1793–1829), of Johann Rudolf Meyer, played the chief parts. After an unsuccessful attempt, defeated by bad weather, in the course of which the Oberaarjoch was crossed twice (this route being much more direct than the long detour through the Lötschental), Rudolf, with the two Valais hunters (Alois Volker and Joseph Bortis), a Guttannen porter named Arnold Abbühl, and a Hasle man, bivouacked on a depression on the southeast ridge of the Finsteraarhorn. Next day (August 16) the whole party attempted the ascent of the Finsteraarhorn from the Studer névé on the east by way of the southeast ridge, but Meyer, exhausted, remained behind. The following day the party crossed the Grünhornlücke to the Aletsch Glacier, but bad weather then put an end to further projects. At a bivouac, probably just opposite the present Konkordia Hut, the rest of the party, having come over the Oberaarjoch and the Grünhornlücke, joined the Finsteraarhorn party. Gottlieb, Rudolf's younger brother, had more patience than the rest and remained longer at the huts near the Märjelensee, where the adventurers had taken refuge. He could make the second ascent (3 September) of the Jungfrau, the Rottalsattel being reached from the east side as is now usual, and his companions being the two Valais hunters.

Before the construction of the Jungfraujoch railway tunnel, the approach from the glaciers on the south side was very long. The first direct route from the valley of Lauterbrunnen was opened in 1865 by Sir George Young, H. Brooke George with the guide Christian Almer. They had to carry ladders with them in order to cross the many crevasses on the north flank. Having spent the night on the rocks of the Schneehorn () they gained next morning the Silberlücke, the depression between the Jungfrau and Silberhorn, and thence in little more than three hours reached the summit. Descending to the Aletsch Glacier they crossed the Mönchsjoch, and passed a second night on the rocks, reaching Grindelwald next day. This route became a usual until the opening of the Jungfraujoch. They used a sled to reach the upper Aletsch Glacier, and were accompanied by Miss Brevoort's favorite dog, Tschingel.

The Jungfrau was climbed via the west side for the first time in 1885 by Fritz and Heinrich von Allmen, Ulrich Brunner, Fritz Graf, Karl Schlunegger and Johann Stäger—all from Wengen. They ascended the Rottal ridge (Innere Rottalgrat) and reached the summit on 21 September. The more difficult and dangerous northeast ridge that connects the summit from the Jungfraujoch was first climbed on 30 July 1911 by Albert Weber and Hans Schlunegger.

The 1863 ascent

The Führerbuch of the Alpine guide Peter Baumann records an ascent of the Jungfrau made by himself with three men from England in July 1863. The foreign climbers were long thought to have been John Tyndall, J. J. Hornby and T. H. Philpott, until in 1958 the records were checked by the Alpine Club and the following conclusion was reached:

<blockquote>On July 23, 1863, Phillpotts, with James Robertson and H.J. Chaytor, climbed the Jungfrau (the entry shown in A.J. 32. 227 was wrongly transcribed by Montagnier, who says ‘T.H. Philpott’ for J. S. Phillpotts). The entry in Peter Baumann’s Führerbuch (facsimile in A.C. archives) says that the trio crossed the Strahlegg Pass and the Oberaarjoch, and then climbed the Jungfrau from the Eggishorn.</blockquote>

Tyndall, Hornby and Philpott were well-known Alpinists, but there is no record of their having attempted the Jungfrau in 1863. Robertson, Chaytor and Phillpotts were novices; they had recently graduated from Oxford University where they had all been keen members of the Oxford University Boat Club.

William Robertson (1839–1892), the leader of the expedition (wrongly called 'James' in the Note quoted above), was an Australian by birth, and the first non-British national to take part in the Oxford and Cambridge Boat Race. He later became a barrister and member of parliament in Australia. He and H. J. Chaytor (possibly the father of the medievalist Henry John Chaytor) were both members of the victorious Oxford team in the 1861 Boat Race. James Surtees Phillpotts (1839–1930) was the third member of the team; he would later become headmaster of Bedford School. The trio had three Swiss guides, Peter Baumann, Peter Kaufmann ("Grabipeter", father of Peter Kaufmann the younger) and Rubi.</blockquote>

Tourism

Named after the Jungfrau, the Jungfrau Region of the Bernese Oberland is a major tourist destination in the Alps and includes a large number of railways and other facilities. While the mountain peak was once difficult to access, the Jungfrau Railway, a rack railway, now goes to the Jungfraujoch railway station at , therefore providing an easy access to the upper Aletsch Glacier and a relatively short access to the Jungfrau itself, the height difference between the station and the summit being only and the horizontal distance being slightly less than . As a result, in the popular mind, the Jungfrau has become a mountain associated with the Bernese Oberland and Interlaken, rather than with Upper Valais and Fiesch.

In 1893, Adolf Guyer-Zeller conceived of the idea of a railway tunnel to the Jungfraujoch to make the glaciated areas on its south side more accessible. The building of the tunnel took 16 years and the summit station was not opened before 1912. The goal was in fact to reach the summit of the Jungfrau with an elevator from the highest railway station, located inside the mountain. The complete project was not realized because of the outbreak of the World War I. The Schilthorn above Mürren, the Männlichen above Wengen, and the Schynige Platte above Wilderswil, offer good views of the Jungfrau and the Lauterbrunnen valley. On the south side, the Eggishorn above Fiesch also offers views of the Jungfrau, across the Aletsch Glacier.

Climbing routes

The normal route follows the traces of the first climbers, but the long approach on the Aletsch Glacier is no longer necessary. From the area of the Jungfraujoch the route to the summit takes only a few hours. Most climbers start from the Mönchsjoch Hut. After a traverse of the Jungfraufirn the route heads to the Rottalsattel (), from where the southern ridge leads to the Jungfrau. It is not considered a very difficult climb but it can be dangerous on the upper section above the Rottalsattel, where most accidents happen.
