Shown above (top photo) is the Tanaro River as it meanders around the vineyards near Barbaresco, Italy, in the northwestern part of Italy's Piedmont region. The Tanaro River is the most important right-side tributary (northeast flowing) of the Po River. Its flow was subjected to a significant river capture episode some 100,000 years ago due to geological subsidence in the area just to the east of the river. This subsidence resulted in a shift of the confluence of the Tanaro and the Po approximately 56 mi (90 km) to the northeast. The river course now passes close to the town of Alba, cutting through white calanchi, composed of Miocene marlstone and sandstone of the (bottom photo). This area of the Langhe hills is famous for its wines and truffles and was recently (2014) inscribed in the UNESCO World Heritage List. Photos taken on November 14, 2017.
