The Prättigau is a geographical region in the canton of Grisons, Switzerland. It consists of the main valley of the river Landquart and the valleys of its side-rivers and creeks. Landquart River, which drains into the Alpine Rhine in the town of the same name, is on its upper end home to the ski resorts of Klosters.
Landquart is a village with a railway junction on the flat floor valley of the Alpine Rhine just north of Chur, the capital of the Grisons.
The Rätikon is a mountain range of the Central Eastern Alps, located at the border between Vorarlberg, Liechtenstein and Graubünden. It is the geological border between the Eastern and Western Alps and stretches from the Montafon as far as the Rhine. In the south, the Prättigau is its limit, and in the north, it is the Walgau. In the east, it borders the Silvretta groups.The Rätikon mountain range derives its name from Raetia, a province of the Roman Empire, named after the Rhaetian (Raeti or Rhaeti) people.
Highest Alemannic is a branch of Alemannic German and is often considered to be part of the German language, even though mutual intelligibility with Standard German and other non-Alemannic German dialects is very limited.
Highest Alemannic dialects are spoken in alpine regions of Switzerland: the Bernese Oberland, in the German-speaking parts of the Canton of Fribourg and Valais, and in the Walser settlements (mostly in Switzerland, but also in Italy and in Austria; see Walser German). In the West, the South and the South-East, they are surrounded by Romance languages; in the North, by High Alemannic dialects. In the Swiss canton of Graubünden (Grisons) only the Walser exclaves in the Romansh part and the Prättigau, Schanfigg and Davos are Highest Alemannic; the Rhine Valley with Chur and Engadin are High Alemannic.
The Plessur Alps are a mountain range in the Alps of eastern Switzerland and are considered to be part of the Western Rhaetian Alps. They are named after the river Plessur, which originates from the center of the ranges. The Plessur Alps are separated from the Glarus Alps in the west by the Rhine valley; from the Rätikon range in the north by the Landquart river valley (Prättigau); from the Albula Alps in the south-east by the Landwasser river valley; from the Oberhalbstein Alps in the south by the Albula river valley.
The Plessur Alps are drained by the rivers Rhine, Plessur, Landwasser and Landquart. The Arosa ski resort lies in the middle of the range.
