The Ill valley is bounded south by the snowy chain of the Rhatikon (highest point, the Scesaplana, 9741 ft., a famous view-point), and of the Silvretta (highest point, Gross Piz Buin, 1 0,880 ft.), both dividing Vorarlberg from Switzerland; slightly to the north-east of Piz Buin is the Dreilanderspitze (10,539 ft.), where the Vorarlberg, Tirolese and Swiss frontiers unite.
Yet, as a matter of fact, several important mountain groups are situated on one or other side of the watershed of the Alps, and form almost independent ranges, being only connected with the main chain by a kind of peninsula: such are the Dauphine Alps, the Eastern and Western Graians, the entire Bernese Oberland, the Todi, Albula and Silvretta groups, the Ortler and Adamello ranges, and the Dolomites of south Tirol, not to speak of the lower Alps of the Vorarlberg, Bavaria and Salzburg.
