Leutascher Ache#
Leutascher Ache River, Tirol, western tributary of the River Isar. The Leutascher Ache rises north of the Karkopf Mountain (alt. 2,469 m), runs through the Wettersteingebirge Mountains and the Mieming Mountains, turns north in the area of Leutasch (alt. 1,136 m) and joins the Isar near Mittenwald (Germany). The valley along the upper course of the Leutascher Ache is called Gais Valley. The valley of the Leutascher Ache was cultivated by the monasteries of Wilten, Polling and Stams. The Leutasch gorge at the Bavarian border was fought over in 1805 in the course of the Napoleonic wars.
