Bletterbach Gorge

A geological treasure

The area extends south of Bolzano, in South Tyrol, and was included on the World Heritage List because it provides a detailed and immediate visual representation of the geological history of the Dolomites.

It is a deep canyon carved out by the stream bearing the same name, about 8 km long and up to 400 meters deep. Here the peaks are not very high, except for the Corno Bianco, and the area is included in the nature reserve Bletterbach Geopark.

Geomorphology and geology

From a geomorphological point of view, the Bletterbach Gorge is a clear example of the effects of water erosion on different types of rocks.

From a geological point of view, the Bletterbach Gorge is a unique site. In this canyon 250 million years of the history of our planet are described in great detail, and the cross-section of rocks ranges from the Upper Permian to the Middle Triassic: from the dark, volcanic rocks at the base to the reddish sandstones that were deposited in an arid tropical environment by transgression and regression phases of the Permian Sea.
The extraordinary number of fossils of reptiles, ammonites, amphibians and plants makes the Bletterbach Gorge one of the most important Permian fossil deposits in the world.
