The Jura Mountains ((:ʒyʁa)) are a sub-alpine mountain range located north of the Western Alps, mainly following the course of the France–Switzerland border. The Jura separates the Rhine and Rhône basins, forming part of the watershed of each. The name "Jura" is derived from ''juria'', a Latinized form of a Celtic stem ''jor-'' "forest".〔Rollier, L. 1903.

''Oliver & Boyd'', 806 pp.; Edinburgh und London.〕 The mountain range gives its name to the French department of Jura, the Swiss Canton of Jura, the Jurassic period of the geologic timescale, and the Montes Jura of the Moon. ==Physiography== The Jura Mountains are a distinct province of the larger Central European uplands. In France, the Jura covers most of the Franche-Comté region, stretching south into the Rhône-Alpes region. The range reaches its highest point at Le Crêt de la Neige in the department of Ain and finds its southern terminus in the northwestern part of the department of Savoie. The north end of the Jura extends into the southern tip of the Alsace region. Roughly 1,600 square kilometers of the mountain range in France is protected by the Jura Mountains Regional Natural Park. The Swiss Jura is one of the three distinct geographical regions of Switzerland, the other being the Swiss plateau and the Swiss Alps. In Switzerland, the range covers the western border with France in the cantons of Basel-Landschaft, Solothurn, Jura, Bern (i.e., Bernese Jura), Neuchâtel, Vaud. Much of the Swiss Jura region has no historical association with Early Modern Switzerland and was incorporated as part of the Swiss Confederacy only in the 19th century. In the 20th century, a movement of Jurassic separatism developed which resulted in the creation of the canton of Jura in 1979. The Swiss Jura has been industrialized since the 18th century and became a major center of the watchmaking industry. The area has several cities at very high altitudes, such as La Chaux-de-Fonds, Le Locle, and Sainte-Croix (renowned for its musical boxes), however, it generally has had a marked decline in population since 1960. The Jura range proper (known as "folded Jura", ''Faltenjura'') is continued as the Table Jura in the cantons of Basel-Landschaft and Aargau, and further to Schaffhausen and into southern Germany towards the Swabian and Franconian plateaus. 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「Jura Mountains」の詳細全文を読む スポンサード リンク
