[XR]noe | human nature - Urdonau 1 (Barockgarten Stift Melk)

The "Urdonau" (ur Danube) ran freely meandering and changing her flow constantly through nowadays Weinviertel into the shallow see of the viennese basin (Wiener Becken). It therefore deposited several layers of gravel terraces (dry cold ages), in which she later dug her bed in again (hightened amount of waterflow in the warmer phases).
