The Appenzell Alps are a mountain range in Switzerland on the northern edge of the Alps. They extend into the cantons of Appenzell Ausserrhoden, Appenzell Innerrhoden and St. Gallen and are bordered by the Glarus Alps to the west and the Rätikon to the south-east.
Churfürsten is a mountain range in the Canton of St. Gallen, Switzerland. They form the natural boundary between the canton's Toggenburg and Sarganserland districts. They are the southernmost range of the Appenzell Alps, separated from the Glarus Alps by the Seez river and Walensee. They consist of a limestone ridge running east to west, with the individual peaks formed by erosion. The ridge is defined much more sharply to the south than to the north, with an almost vertical drop of several hundred meters towards Walenstadtberg and eventually Lake Walensee at 419 m. The southern slope of the range was significantly formed by the Rhine Glacier during the Würm glaciation.
