Mont Blanc


Mont Blanc is the second-highest mountain in Europe after Mount Elbrus. It is the highest mountain in the Alps, and rises above sea level and is the eleventh-most prominent peak in the world. The mountain stands in a range called the Graian Alps, between the regions of Aosta Valley, Italy, and Savoie and Haute-Savoie, France. The location of the summit is on the watershed line between the valleys of Ferret and Veny in Italy and the valleys of Montjoie, and Arve in France, on the border between the two countries.
The Mont Blanc massif is popular for outdoor activities like hiking, climbing, trail running and winter sports like skiing, and snowboarding. The most popular route is the Goûter Route, which typically takes two days.
The three towns and their communes which surround Mont Blanc are Courmayeur in Aosta Valley, Italy; and Saint-Gervais-les-Bains and Chamonix in Haute-Savoie, France. The latter town was the site of the first Winter Olympics. A cable car ascends and crosses the mountain range from Courmayeur to Chamonix, through the Col du Géant. The Mont Blanc Tunnel, constructed between 1957 and 1965, runs beneath the mountain and is a major trans-Alpine transport route.

History

Since 1760 Swiss naturalist Horace-Bénédict de Saussure began to go to Chamonix to observe Mont Blanc. He tried with the Courmayeur mountain guide Jean-Laurent Jordaney, native of Pré-Saint-Didier, who accompanied De Saussure since 1774 on the Miage Glacier and on mont Crammont.
The first recorded ascent of Mont Blanc was on 8 August 1786 by Jacques Balmat and the doctor Michel Paccard. This climb, initiated by Horace-Bénédict de Saussure, who gave a reward for the successful ascent, traditionally marks the start of modern mountaineering. The first woman to reach the summit was Marie Paradis in 1808.
Nowadays the summit is ascended by an average of 20,000 mountaineer-tourists each year. It could be considered a technically easy, yet arduous, ascent for someone who is well-trained and acclimatized to the altitude. From l'Aiguille du Midi, Mont Blanc seems quite close, being higher. But while the peak seems deceptively close, La Voie des 3 Monts route requires much ascent over two other 4,000 m mountains, Mont Blanc du Tacul and Mont Maudit, before the final section of the climb is reached and the last 1,000 m push to the summit is undertaken.
Each year climbing deaths occur on Mont Blanc, and on the busiest weekends, normally around August, the local rescue service performs an average of 12 missions, mostly directed to aid people in trouble on one of the normal routes of the mountain. Some routes require knowledge of high-altitude mountaineering, a guide, and all require proper equipment. All routes are long and arduous, involving delicate passages and the hazard of rock-fall or avalanche. Climbers may also suffer altitude sickness, occasionally life threatening, particularly if they do not acclimatize to it.

Ownership of the summit

At the scale of the Mont Blanc massif, the border between Italy and France passes along most of the main Alpine watershed, from the Aiguille des Glaciers to Mont Dolent. However, its precise location near the summits of Mont Blanc and nearby Dôme du Goûter is disputed since the 18th century. Italian officials claim the border follows the watershed, splitting both summits between Italy and France, while French officials claim the border avoids the two summits, making both of them in France only. The size of these two disputed areas are approximately 65 ha on Mont Blanc and 10 ha on Dôme du Goûter.
Since the French Revolution, the issue of the ownership of the summit has been debated. From 1416 to 1792, the entire mountain was within the Duchy of Savoy. In 1723, the Duke of Savoy, Victor Amadeus II, acquired the Kingdom of Sardinia. The resulting state of Sardinia was to become preeminent in the Italian unification. In September 1792, the French revolutionary Army of the Alps under Anne-Pierre de Montesquiou-Fézensac seized Savoy without much resistance and created a department of the Mont-Blanc. In a treaty of 15 May 1796, Victor Amadeus III of Sardinia was forced to cede Savoy and Nice to France. In article 4 of this treaty it says: "The border between the Sardinian kingdom and the departments of the French Republic will be established on a line determined by the most advanced points on the Piedmont side, of the summits, peaks of mountains and other locations subsequently mentioned, as well as the intermediary peaks, knowing: starting from the point where the borders of Faucigny, the Duchy of Aoust and the Valais, to the extremity of the glaciers or Monts-Maudits: first the peaks or plateaus of the Alps, to the rising edge of the Col-Mayor". This act further states that the border should be visible from the town of Chamonix and Courmayeur. However, neither is the peak of the Mont Blanc visible from Courmayeur nor is the peak of the Mont Blanc de Courmayeur visible from Chamonix because part of the mountains lower down obscure them.
After the Napoleonic Wars, the Congress of Vienna restored the King of Sardinia in Savoy, Nice and Piedmont, his traditional territories, overruling the 1796 Treaty of Paris. Forty-five years later, after the Second Italian War of Independence, it was replaced by a new legal act. This act was signed in Turin on 24 March 1860 by Napoleon III and Victor Emmanuel II of Savoy, and deals with the annexation of Savoy. A demarcation agreement, signed on 7 March 1861, defined the new border. With the formation of Italy, for the first time Mont Blanc was located on the border of France and Italy.
The 1860 act and attached maps are still legally valid for both the French and Italian governments. One of the prints from the 1823 Sarde Atlas positions the border exactly on the summit edge of the mountain. The convention of 7 March 1861 recognises this through an attached map, taking into consideration the limits of the massif, and drawing the border on the icecap of Mont Blanc, making it both French and Italian. Watershed analysis of modern topographic mapping not only places the main summit on the border, but also suggests that the border should follow a line northwards from the main summit towards Mont Maudit, leaving the southeast ridge to Mont Blanc de Courmayeur wholly within Italy.
Although the Franco-Italian border was redefined in both 1947 and 1963, the commission made up of both Italians and French ignored the Mont Blanc issue.
The area from the Torino Hut to the summit is under the control of the Italian authority. NATO uses Italian military maps to operate. In the early 21st century, administration of the mountain is shared between the Italian town of Courmayeur and the French town of Saint-Gervais-les-Bains, although the larger part of the mountain lies within the commune of the latter.
In 2015, press reports suggested that claims by Italian mountaineers and cartographers on the disputed territory were still ongoing. As of 2020, the Swiss National Map, which covers the massif at 1:50'000 scale, shows both disputed areas around Mont Blanc and Dôme du Goûter in a neutral way, after previously following the French interpretation of the border until 2018.

Vallot

The first professional scientific investigations on the summit were conducted by the botanist–meteorologist Joseph Vallot at the end of the 19th century. He wanted to stay near the top of the summit, so he built his own permanent cabin.

Janssen observatory

In 1890, Pierre Janssen, an astronomer and the director of the Meudon astrophysical observatory, considered the construction of an observatory at the summit of Mont Blanc. Gustave Eiffel agreed to take on the project, provided he could build on a rock foundation, if found at a depth of less than below the ice. In 1891, the Swiss surveyor Imfeld dug two horizontal tunnels 12 m below the ice summit but found nothing solid. Consequently, the Eiffel project was abandoned.
Despite this, the observatory was built in 1893. During the cold wave of January 1893, a temperature of was recorded on Mont Blanc, being the lowest ever recorded there.
Levers attached to the ice supported the observatory. This worked to some extent until 1906, when the building started leaning heavily. The movement of the levers corrected the lean slightly, but three years later, a crevasse started opening under the observatory. It was abandoned. Eventually the building fell, and only the tower could be saved.

Air crashes

The mountain was the scene of two fatal air crashes; Air India Flight 245 in 1950 and Air India Flight 101 in 1966. Both planes were approaching Geneva Airport and the pilots miscalculated their descent; 48 and 117 people, respectively, died. The latter passengers included nuclear scientist Homi J. Bhabha, known as the "father" of India's nuclear programme.

Tunnel

In 1946, a drilling project was initiated to carve a tunnel through the mountain. The Mont Blanc tunnel would connect Chamonix, France and Courmayeur, Italy, and become one of the major trans-Alpine transport routes between the two countries. In 1965, the tunnel opened to vehicle traffic with a length of.

1999 disaster

In 1999, a transport truck caught fire in the tunnel beneath the mountain. In total 39 people were killed when the fire raged out of control. The tunnel was renovated in the aftermath to increase driver safety, reopening after three years.

Incidents involving children

The record for the youngest person to climb Mont Blanc was set in 2009 by 10-year-old Asher Silver.
In July 2014, an American entrepreneur and traveler Patrick Sweeney attempted to break the record with his nine-year-old son P.J. and 11-year-old daughter Shannon. They were caught in avalanche, luckily escaped death and decided not to pursue their attempt.
In August 2014, an unknown Austrian climber with his 5-year-old son were intercepted by mountain gendarmes at 3,200 metres and forced to turn around.
On 5 August 2017, 9-year-old Hungarian twins and their mother were rescued from 3,800 metres by helicopter while their father and family friend continued their summit attempt.

Elevation

The summit of Mont Blanc is a thick, perennial ice-and-snow dome whose thickness varies. No exact and permanent summit elevation can therefore be determined, though accurate measurements have been made on specific dates.
For a long time, its official elevation was. In 2002, the IGN and expert surveyors, with the aid of GPS technology, measured it to be.
After the 2003 heatwave in Europe, a team of scientists re-measured the height on 6 and 7 September. The team was made up of the glaciologist Luc Moreau, two surveyors from the GPS Company, three people from the IGN, seven expert surveyors, four mountain guides from Chamonix and Saint-Gervais and four students from various institutes in France. This team noted that the elevation was, and the peak was away from where it had been in 2002.
After these results were published, more than 500 points were measured to assess the effects of climate change and the fluctuations in the height of the mountain at different points. Since then, the elevation of the mountain has been measured every two years.
The summit was measured again in 2005, and the results were published on 16 December 2005. The height was found to be, more than the previous recorded height. The rock summit was found to be at, some west of the ice-covered summit.
In 2007, the summit was measured at and in 2009 at.
In 2013, the summit was measured at and in 2015 at.
From the summit of Mont Blanc on a clear day, the Jura, the Vosges, the Black Forest and the Massif Central mountain ranges can be seen, as well as the principal summits of the Alps.

Fatalities

A 1994 estimate suggests there had been 6,000 to 8,000 alpinist fatalities in total, more than on any other mountain. Despite unsubstantiated claims recurring in media that "some estimates put the fatality rate at an average of 100 hikers a year", actual reported annual numbers at least since the 1990s are between 10 and 20: in 2017, fourteen people died out of 20,000 summit attempts and two remained missing; with 15 in 2018 as of August.
A French study on the especially risky "Goûter couloir, on the normal route on Mont Blanc" and necessary rescue operations found that between 1990 and 2011, there were 74 deaths "between the Tête Rousse refuge and the Goûter refuge ". There were 17 more in 2012–15, none in 2016 and 11 in 2017.
Note that these numbers do not count the fatalities of Air India Flight 245 and Air India Flight 101, two planes under the Air India airline that crashed into Mont Blanc.

Climbing routes

Several classic climbing routes lead to the summit of Mont Blanc:
Recent temperature rises and heatwaves, such as those of the summers of 2015 and 2018, have had significant impacts on many climbing routes across the Alps, including those on Mont Blanc. For example, in 2015, the Grand Mulets route, previously popular in the 20th century, was blocked by virtually impenetrable crevasse fields, and the Gouter Hut was closed by municipal decree for some days because of very high rockfall danger, with some stranded climbers evacuated by helicopter.
In 2016 a crevasse opened at high altitude, also indicating previously unobserved glacial movements. The new crevasse forms an obstacle to be scaled by climbing parties on the final part of the itinerary to the top shared by the popular Goûter Route and the Grand Mulets Route.

Exploits and incidents

Cinema and television

The Mont Blanc massif is being put forward as a potential World Heritage site because of its uniqueness and its cultural importance, considered the birthplace and symbol of modern mountaineering. It would require the three governments of Italy, France and Switzerland to make a request to UNESCO for it to be listed.
Mont Blanc is one of the most visited tourist destinations in the world, and for this reason, some view it as threatened. Pro-Mont Blanc published in 2002 the book Le versant noir du mont Blanc, which exposes current and future problems in conserving the site.
In 2007, Europe's two highest toilets were taken by helicopter to the top of Mont Blanc. They are also serviced by helicopter. They will serve 30,000 skiers and hikers annually, helping to alleviate the discharge of urine and faeces that spreads down the mountain face with the spring thaw, and turns it into 'Mont Marron'.
Global warming has begun to melt glaciers and cause avalanches on Mont Blanc, creating more dangerous climbing conditions.
