The Grand Ballon ((ドイツ語:Großer Belchen)) or Great Belchen is the highest mountain of the Vosges, located 25 kilometres northwest of Mulhouse, France. It is also the highest point of the Alsace French region.〔''France Region High Points'', web-page on (www.peakbagger.com )〕 Some still call it ''Ballon de Guebwiller'', after the name of the closest town, Guebwiller, located 8 km to the east. It is 1,423.7 metres high, according to the Institut Géographique National (IGN). The well known Route des Crêtes (French for "route of the peaks") circumvents the mountain top around east, crossing a mountain pass at an altitude of 1,343 m, between Le Markstein winter sports station and Hartmannswillerkopf, a rocky spur. The mountain is part of the so-called Belchen System, a group of mountains with the name "Belchen" (in German) that may have been part of a Celtic sun calendar. == Climate == Along with the Hohneck the summit of the Grand Ballon is the coldest and windiest point in Alsace. A record low of -30.2 °C was recorded 10 February 1956, a record high of 29 °C was recorded 13 August 2003. The difference between the Grand Ballon and the neighboring plain (Mulhouse area) usually ranges from 7 °C to 10 °C and is higher in summertime. Winter snow cover is usually more than above of altitude. The highest snow accumulation ever recorded was 7 March 2006; in 1969 and 1970 the snow cover was above . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Grand Ballon」の詳細全文を読む スポンサード リンク
