Swiss Alps

Template:Short description Template:Use dmy dates The Alpine region of Switzerland, conventionally referred to as the Swiss Alps, represents a major natural feature of the country and is, along with the Swiss Plateau and the Swiss portion of the Jura Mountains, one of its three main physiographic regions. The Swiss Alps extend over both the Western Alps and the Eastern Alps, encompassing an area sometimes called Central Alps. While the northern ranges from the Bernese Alps to the Appenzell Alps are entirely in Switzerland, the southern ranges from the Mont Blanc massif to the Bernina massif are shared with other countries such as France, Italy, Austria and Liechtenstein.

The Swiss Alps comprise almost all the highest mountains of the Alps, such as Dufourspitze (Template:Convert), the Dom (Template:Convert), the Liskamm (Template:Convert), the Weisshorn (Template:Convert) and the Matterhorn (Template:Convert). The other following major summits can be found in this list of mountains of Switzerland.

Since the Middle Ages, transit across the Alps played an important role in history. The region north of St Gotthard Pass became the nucleus of the Swiss Confederacy in the early 14th century.

Geography

Swiss Alps seen from the Swiss Jura in December 2010

The Alps cover 60% of Switzerland's total Template:Convert surface area, making it one of the most alpine countries. Despite the fact that Switzerland covers only 14% of the Alps total Template:Convert area, 48 out of 82 alpine four-thousanders are located in the Swiss Alps and practically all of the remaining 34 are within Template:Convert of the country's border.

The glaciers of the Swiss Alps cover an area of Template:Convert — 3% of the Swiss territory, representing 44% of the total glaciated area in the Alps i.e. Template:Convert.

The Swiss Alps are situated south of the Swiss Plateau and north of the national border. The limit between the Alps and the plateau runs from Vevey on the shores of Lake Geneva to Rorschach on the shores of Lake Constance, passing close to the cities of Thun and Lucerne. The not well defined regions in Switzerland that lie on the margin of the Alps, especially those on the north side, are called the Swiss Prealps (Alpine foothills) (Template:Langx, Template:Langx, Template:Langx). The Swiss Prealps are mainly made of limestone and they generally do not exceed Template:Convert.

The Alpine cantons (from highest to lowest) are Valais, Bern, Grisons (), Uri, Glarus, Ticino, St. Gallen, Vaud, Obwalden, Nidwalden, Schwyz, Appenzell Innerrhoden, Appenzell Ausserrhoden, Fribourg, Lucerne and Zug. The countries with which Switzerland shares mountain ranges of the Alps are (from west to east): France (French Alps), Italy, Austria, Liechtenstein and Germany (Bavarian Alps).

Ranges

The Alps are usually divided into two main parts, the Western Alps and Eastern Alps, whose division is along the Rhine from Lake Constance to the Splügen Pass. The western ranges occupy the greatest part of Switzerland while the more numerous eastern ranges are much smaller and are all situated in the canton of Graubünden. The latter is part of the Central Eastern Alps, except the Ortler Alps which belong to the Southern Limestone Alps. The Pennine, Bernese and Bernina Range are the highest ranges of the country, they contain respectively 38, 9 and 1 summit over Template:Convert. The lowest range is the Appenzell Alps culminating at Template:Convert.

Hydrography

Rivers

File:Rhine.jpg

Rhine Gorge in Graubünden

The north side of the Swiss Alps is drained by the Rhône, Rhine and Inn (which is part of the Danube basin) while the south side is mainly drained by the Ticino (Po basin). The rivers on the north empty into the Mediterranean, North and Black Sea, on the south the Po empty in the Adriatic Sea. The major triple watersheds in the Alps are located within the country, they are: Piz Lunghin, Witenwasserenstock and Monte Forcola. Between the Witenwasserenstock and Piz Lunghin runs the European Watershed separating the basin of the Atlantic (the North Sea) and the Mediterranean Sea (Adriatic and the Black Sea). The European watershed lies only partially on the main chain. Switzerland possesses 6% of Europe's freshwater, and is sometimes referred to as the "water tower of Europe".

Lakes

File:Dix.jpg

The Lac des Dix in Valais

Since the highest dams are located in Alpine regions, many large mountain lakes are artificial and are used as hydroelectric reservoirs. Some large artificial lakes can be found above Template:Convert, but natural lakes larger than Template:Cvt are generally below Template:Convert, with the exceptions of lakes in the Engadin such as Lake Sils, and Oeschinen in the Bernese Oberland. The melting of low-altitude glaciers can generate new lakes, such as the Template:Cvt large Triftsee which formed between 2002 and 2003.

Glaciers

The last glaciations greatly transformed Switzerland's landscape. Many valleys of the Swiss Alps are U-shaped due to glacial erosion. During the maximum extension of the Würm glaciation (18,000 years ago) the glaciers completely covered the Swiss Plateau, before retreating and leaving remnants only in high mountain areas. In modern times the Aletsch Glacier in the western Bernese Alps is the largest and longest in the Alps, reaching a maximum depth of 900 meters at Konkordiaplatz. Along with the Fiescher and Aar Glaciers, the region became a UNESCO World Heritage Site in 2001. An effect of the retreat of the Rhine Glacier some 10,000 years ago was the Flims Rockslide, the biggest still visible landslide worldwide.

Monitoring glacial changes over time

PERMOS (The Swiss Permafrost Monitoring Network) is an operational monitoring service, and its main goal is to create long-term scientific documentation of the permafrost changes in the Swiss Alps. To accurately represent the current conditions of the Alps, the network records permafrost temperatures and thermal changes in boreholes, the bottom temperature of the snow cover, ground surface temperature, and the development of snow cover. The network additionally takes air photos periodically from selected areas. These monitoring strategies continue to develop as new research and data are recorded over time. The glaciers in the Swiss Alps have lost around half their volume during the last 90–120 years.

Hydroelectricity Impacts due to Glacial Melting

Switzerland has been using this concerning transition in climate as a positive opportunity to develop new innovations and to change the ways that energy is being produced in the country. Switzerland depends on the use of hydroelectricity to power nearby communities, but as glaciers melt and stop refreezing, the melting that creates the energy ceases to exist. Researchers have been evaluating how the topography will change as the glaciers begin to decrease and they are looking more deeply into potential construction costs, energy production, and future problems they might encounter with these new developments. Switzerland is one of many countries that need to begin to think about the future of energy production in response to climate change. Switzerland is paving the way for a new wave of innovation and creative problem solving that the rest of the world will eventually need to follow.

Geology

File:Lauterbrunnental train.jpg

Lauterbrunnen Valley in the Bernese Alps, a deep U-shaped valley that resulted from erosion by glaciers

The composition of the great tectonic units reflects the history of the formation of the Alps. The rocks from the Helvetic zone on the north and the Austroalpine nappes – Southern Alps on the south come originally from the European and African continent respectively. The rocks of the Penninic nappes belong to the former area of the Briançonnais microcontinent and the Tethys Ocean. The closure of the latter by subduction under the African plate (Piemont Ocean first and Valais Ocean later) preceded the collision between the two plates and the so-called alpine orogeny. The major thrust fault of the Tectonic Arena Sardona in the eastern Glarus Alps gives a visible illustration of mountain-building processes and was therefore declared a UNESCO World Heritage. Another fine example gives the Alpstein area with several visible upfolds of Helvetic zone material.

With some exceptions, the Alps north of Rhône and Rhine are part of the Helvetic Zone and those on the south side are part of the Penninic nappes. The Austroalpine zone concerns almost only the Eastern Alps, with the notable exception of the Matterhorn.

Environment and climate

To protect endangered species some sites have been brought under protection. The Swiss National Park in Graubünden was established in 1914 as the first alpine national park. The Entlebuch area was designated a biosphere reserve in 2001. The largest protected area in the country is the Parc Ela, opened in 2006, which covers an area of 600 square kilometres. The Jungfrau-Aletsch Protected Area is the first World Heritage Site in the Alps.

Climate zones

As the temperature decreases with altitude (Template:Convert per Template:Convert on yearly average), three different altitudinal zones, each having distinct climate, are found in the Swiss Alps:

• Subalpine zone

File:Val Trupchun.jpg

Tree line in the national park

Liskamm (Template:Convert), above the Gorner Glacier

The Subalpine zone is the region that lies below the tree line. It is the most important region as it is the largest of the three and contains almost all human settlements as well as the productive areas. The forests are mainly composed of conifers above Template:Convert, the deciduous tree forest is confined to lower elevations. The upper limit of the Subalpine zone is located at about Template:Convert on the north side of the Alps and about Template:Convert on the south side. It can, however, differ in some regions such as the Appenzell Alps (Template:Convert) or the Engadin valley (Template:Convert).

• Alpine zone

The Alpine zone is situated above the tree line and is clear of trees due to low average temperatures. It contains mostly grass and small plants along with mountain flowers. Below the permafrost limit (at about Template:Convert), the alpine meadows are often used as pastures. Some villages can still be found on the lowest altitudes such as Riederalp (Template:Convert) or Juf (Template:Convert). The extent of the Alpine zone is limited by the first permanent snow, its altitude greatly varies depending on the location (and orientation), it comprises between Template:Convert.

• Glacial zone

The glacial zone is the area of permanent snow and ice. When the steepness of the slope is not too high it results in an accumulation and compaction of snow, which transforms into ice. The glacier-formed then flows down the valley and can reach as far down as Template:Convert (the Upper Grindelwald Glacier). Where the slopes are too steep, the snow accumulates to form overhanging seracs, which periodically fall off due to the downward movement of the glacier and cause ice avalanches. The Bernese Alps, Pennine Alps, and Mont Blanc Massif contain most of the glaciated areas in the Alps. Except for research stations such as the Sphinx Observatory, no settlements are to be found in those regions.

Impact of glacial melting

Due to the change in weather patterns, the summers are expected to continue getting warmer and drier, while the winters are expected to become moister. This change in the weather increases the chances of flooding with heavier rainfall, the melting of permafrost zones, a change in the geography and wildlife, and the occurrence of more deadly rock slides. Furthermore, natural hazards are occurring more frequently, such as floods, avalanches, and landslides. Additionally, the water supply that the glaciers originally provided is on the decline, which is problematic for producing energy, agricultural practices, and other human use. Finally, the glacial melting puts the economy at risk because there will be less incoming financial revenue from the tourism and recreation services that these glaciers and ecosystems typically provide. All of these impacts will disrupt the nearby communities and require that updated infrastructure and safety measures be put into place to prevent mass destruction.

Travel and tourism

Glacier 3000 cable car

Tourism in the Swiss Alps began with the first ascents of the main peaks of the Alps (Jungfrau in 1811, Piz Bernina in 1850, Monte Rosa in 1855, Matterhorn in 1856, Dom in 1858, Weisshorn in 1861) mostly by British mountain climbers accompanied by the local guides. The construction of facilities for tourists started in the mid-nineteenth century with the building of hotels and mountain huts (creation of the Swiss Alpine Club in 1863) and the opening of mountain train lines (Rigi in 1873, Pilatus in 1889, Gornergrat in 1898). The Jungfraubahn opened in 1912; it leads to the highest railway station in Europe, the Jungfraujoch.

Summer tourism

Switzerland enjoys a network of well-maintained trails with a total length of Template:Convert, of which 23,000 are located in mountainous areas. Many mountains attract a large number of alpinists from around the world, especially the Template:Convert summits and the great north faces (Eiger, Matterhorn and Piz Badile). The large winter resorts are also popular destinations in summer, as most of aerial tramways operate through the year, enabling hikers and mountaineers to reach high altitudes without much effort. The Klein Matterhorn is the highest summit of the European continent to be served by cable car.

Winter tourism

Highest ski area in Europe above Zermatt

The major destinations for skiing and other winter sports are located in Valais, Bernese Oberland and Grisons (). Some villages are car-free and can be accessed only with public transports such as Riederalp and Bettmeralp. Zermatt and Saas-Fee have both summer ski areas. The ski season starts from as early as November and runs to as late as May; however, the majority of ski resorts in Switzerland tend to open in December and run through to April. The most visited places are:

File:Altes Zermatt.jpg

Due to strong political will by the citizenry, Zermatt remains car-free and retains much of its original character

• Davos – Klosters GR
• Zermatt VS (car-free village)
• Engadin – St. Moritz GR
• Lenzerheide – Arosa GR
• Jungfrauregion: Grindelwald – Mürren – Wengen BE (car-free villages)
• Les quatre vallées: Verbier – Nendaz VS
• LAAX: Flims – Laax GR
• Aletsch Arena: Riederalp – Bettmeralp – Fiesch VS (car-free villages)

• Silvretta Arena: Samnaun GR and Ischgl in Austria
• Crans Montana VS
• Saas-Fee VS

Other important destinations on the regional level are Engelberg-Titlis (Central Switzerland / OW) and Gotthard Oberalp Arena with Andermatt (Central Switzerland / UR) and Sedrun (GR), Leysin-Les Mosses, Villars-sur-Ollon, Les Diablerets-Glacier 3000 (all VD), Leukerbad (VS), Savognin, Scuol, Obersaxen, Breil/Brigels (all GR), Meiringen – Hasliberg (BE), Sörenberg (LU), Klewenalp with Beckenried and Emmetten (both NW), Melchsee-Frutt (OW), Flumserberg and Pizol (both Sarganserland in SG), Toggenburg with Wildhaus – Unterwasser – Alt St. Johann (SG), Hoch-Ybrig and Stoos (all SZ), Braunwald and Elm (GL), Airolo and Bosco/Gurin (TI) and many more.

The first person to ski in Grindelwald, Switzerland was Englishmen Gerald Fox (a resident of Tone Dale House in England) who put his skis on in his hotel bedroom in 1881 and walked out through the hotel Bar to the slopes wearing them.

Snow activities

Some major sporting activities include:

• Skiing
• Snowboarding
• Snow sled-biking
• Downhill snow Mountain Biking
• Snowmobiling (as well as snowmobile tours and rides)

Climate change

Climate change is impacting European Alpine tourism due to the increasing number and intensity of natural hazards, and it is endangering the accessibility and infrastructure of tourism destinations. Melting glaciers are affecting the attractiveness of the Alpine landscape, increasing winter temperatures will result in a shorter skiing season, and these climate changes are limiting the amount of snow coverage produced. All of these climate and geographical factors are leading to a smaller number of visitors and reduced revenues which can have an intense economic impact on winter tourism. In response to these changes, Switzerland has turned to the production of artificial snow to match the demand for these tourist destinations and to uphold the structure and well-being of the economy.

Transport

Lötschberg railway line

The Swiss Alps and Switzerland enjoy an extensive transport network. Virtually every mountain village can be reached by public transport, either by rail, bus, funicular, cable car, or usually a combination of them. The main companies of the coherently integrated public transport system are:

• Swiss Federal Railways (SBB CFF FFS)
• BLS
• Südostbahn (SOB)
• Rhaetian Railway (RhB)
• Matterhorn Gotthard Bahn (MGB)
• GoldenPass Line
• PostBus ( / / / )

In addition, many mountans and summits are accessible by public transport.

Most of the mountain regions are within 1 to 3 hours travel of Switzerland's main cities and their respective airport. The Engadine in Graubünden is between 3 and 6 hours away from the large cities; the train journey itself, with the panoramic Glacier Express or Bernina Express, is popular with tourists. Most tourism-oriented trains run under the Panorama Express (PE) category.

The Engadin Airport near St. Moritz at an altitude of Template:Convert is the highest in Europe.

The crossing of the Alps is a key issue at national and international levels, as the European continent is at places divided by the range. Since the beginning of industrialisation Switzerland has improved its transalpine network; it began in 1882, by building the Gotthard Rail Tunnel, followed in 1906 by the Simplon Tunnel and 1913 by the Lötschberg Tunnel, and more recently, in 2007, by the Lötschberg Base Tunnel. The Template:Cvt long Gotthard Base Tunnel, the longest railway tunnel of the world, opened in 2016 and provides a direct flat rail link through the Alps.

Although not a common practice in Switzerland, a few mountains and summits are named after people.

Also, a large number of peaks outside the Alps were named or nicknamed after Swiss mountains, such as the Wetterhorn Peak in Colorado or the Matterhorn Peak in California (see the Matterhorn article for a list of Matterhorns in the world).

The confluence of the Baltoro Glacier and the Godwin-Austen Glacier south of K2 in the Karakoram range was named after the Konkordiaplatz by European explorers.
