Which mountain in the Alps between Switzerland and Italy was created by marine sedimentary rocks folding into mountain peaks?
Alps The Alps ( ; French: "Alpes" ] ; German: "Alpen" ] ; Italian: "Alpi" ] ; Romansh: "Alps" ; Slovene: "Alpe" ] ) are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately 1,200 km across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at 4810 m is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet).
Säntis At 2,501.9 metres above sea level, Säntis is the highest mountain in the Alpstein massif of northeastern Switzerland. It is also the culminating point of the whole Appenzell Alps, between Lake Walen and Lake Constance. Shared by three cantons, the mountain is a highly visible landmark thanks to its exposed northerly position within the Alpstein massif. As a consequence, houses called "Säntisblick" (English: "Säntis view") can be found in regions as far away as the Black Forest in Germany. Säntis is among the most prominent summits in the Alps and the most prominent summit in Europe with an observation deck on the top. The panorama from the summit is spectacular. Six countries can be seen if the weather allows: Switzerland, Germany, Austria, Liechtenstein, France, and Italy.
