Salhöhe Pass (el. 779 m.) is a mountain pass in the Jura Mountains of Switzerland between Kienberg in the canton of Solothurn and Erlinsbach in the canton of Aargau.
It connects Kienberg in Solothurn and Erlinsbach in Aargau. The pass road has a maximum grade of 9 percent. Although it is the shortest route between Aarau and Basel, traffic over the pass is moderate.
Further Austria, Outer Austria or Anterior Austria (Latin: Austria anterior; German: Vorderösterreich, formerly die Vorlande (pl.)) was the collective name for the early (and later) possessions of the House of Habsburg in the former Swabian stem duchy of south-western Germany, including territories in the Alsace region west of the Rhine and in Vorarlberg.
While the territories of Further Austria west of the Rhine and south of Lake Constance (except Konstanz itself) were gradually lost to France and the Swiss Confederacy, those in Swabia remained under Habsburg control until the Napoleonic Era, with Vorarlberg still forming a part of modern Austria.
