Partnach Gorge, Germany

The Partnach Gorge (German: Partnachklamm) is a deep gorge that has been incised by a mountain stream, the Partnach, in the Reintal valley near the south German town of Garmisch-Partenkirchen. The gorge is 702 metres (2,303 ft) long and, in places, over 80 metres (260 ft) deep. It was designated a natural monument in 1912.In the Triassic, about 240 million years ago, on the bed of a shallow sea, dark grey, relatively hard layers of Alpine muschelkalk, so-called Wurstelkalk, were laid down in the area of the present day Partnach Gorge. On the bead-like strata of this rock the traces of the burrowing and feeding of marine animals can still be seen. Importantly, about 5 million years later, softer marls were deposited in the same marine basin, which today are known as Partnach Strata (Partnach-schichten).

In the course of the subsequent Alpine mountain folding the so-called Warnberg Saddle (Warnberger Sattel) was formed from these rock strata. The erosion force of the Partnach stream, fed from the Schneeferner glacier on the Zugspitzplatt plateau, was great enough to carry away quickly the softer layers, to keep pace with the continued uplifting of the terrain and thus to cut into the hard Alpine muschelkalk as well. Today the river forms the typically narrow valley shape of a gorge (Klamm) in the area of the muschelkalk rocks, while the areas of softer Partnach strata to the north and south have a wider valley cross-section.

The gorge was already being used by local peoples in the 18th century who, at risk of their lives, transported firewood from the Reintal valley on timber rafts to Partenkirchen. From the 18th century to the 1960s the river and the gorge were used as a rafting stream. In spring the logs, marked with an owner's symbol (Hausmach), were thrown into the stream and carried by meltwaters down the valley. The freeing of jammed logs required much daring and men were frequently lost in carrying out this dangerous task. Boards on a wayside cross between the Olympic Stadium and the entrance to the gorge bear witness to these accidents.

Since 1912 the gorge has been developed for tourists and can be visited all year round. An entry fee is charged in summer between 8 am and 6 pm and in winter between 9 am and 5 pm. Outside these times the gorge may be visited at individual risk. During snowmelt in spring the gorge may also be closed for a short period. Source: Wikipedia
