Flight Vienna - Amsterdam, morning view across the Danube in S direction. The hydropower plant of Ybbs-Persenbeug can be seen near the left edge of the scene. The village in the lower right corner is Waldhausen im Strudengau. Uplift of the Bohemian Massif (Waldviertel and Mühlviertel in the foreground, Neustadtler Platte in the background) related to the formation of the Alps has triggered antecedent erosion by the Danube, resulting in the valley section known as Strudengau.
