Description

The Johannesbachklamm is located at the eastern end of the town Würflach. It is a gorge which is about one kilometer long and 60m deep, with almost vertical walls. A trail named Erlebnisweg Johannesbachklamm with 6km length leads through the gorge and back to Würflach.

This gorge is located in Wettersteinkalk, the typical limestone of the Nördliche Kalkalpen (Northern Limestone Alps). The tektonic situation weakened the limestone here, and so the water eroded the limestone rather fast. Like most gorges it is rather young - in geologic terms - created by the melting water of Ice Age glaciers. The gorge connects two lowlands, the valley of Greith and the Steinfeld, which ends at Würflach. The creek flows around Rosental on shist rocks named Werfener Schichten, which are relatively soft and easily eroded. Then it enters the hard and resistant limestone, where it cut the gorge. When it leaves the gorge, the rocks change again, whe have now Rohrbacher Konglomerat. a conglomerate formed from the debris of the Alps, but rather young and easily eroded.

The gorge shows all the typical erosional forms, like scallops and dolly tubs. The biggest dolly tub is named Marientritt or Liebfrauentritt, which means "step of Mary". There is a legend which explains the name.

The gorge was developed by the Wiener Naturfreunde (Friends of Nature, Vienna) in 1902, by building trails and bridges. But the gorge is regularly flooded and each flood destroyed part of the trail. In 1926 was an extremely heavy flood, which destroyed not only the gorge, but also buildings in the town. As a result the gorge was closed for the public and the community erected a dam at the end of the gorge and canalized the river through the town. The dam was completed in 1928, and since this year a restaurant was lending rowing boats on the lake. This was discontinues when the lake filled with mud only ten years later.

The trails and bridges in the gorge were restored in 1960, now by the town, who manage the gorge since then, and the groge was reopened. Thats more or less the current state of the trails.

The lake was reactivated in 1999 and after a flood in 2006 it was clear that the lake was vital as a buffer for heavy rains. The lake was enlarged and is now regularly cleaned by the community.
