Deep gorge that cuts various sedimentary strata (overlying Lower Permian quartz porphyry) and leads up to the white dolomite peak ('Sarl Dolomite') of the Weißhorn Mtn. (2317 m). This site is famous for some fossils and fossilised animal tracks. An educational geological-palaeontological trail leads through the gorge. The gorge, also known as “Grand Canyon of the Dolomites”, is a highly significant geological site, because it allows to have a look, stratum by stratum, at the geological period ranging from the Lower Permian up to the Anisian, crossing through one of the greatest biological events that has ever been seen on Earth: the Permian/Triassic extinction. A small educational museum ('Geoparc') is located at the parking lot. The gorge is a protected area.

Traces of old mining works on minor disseminated sulphide ores (bound to plant remnants now turned into coal) are found at the locality 'Taubenleck'.

Few hundreds of millimetre-sized granules of the most ancient Italian amber were found in 1992 in Upper Permian argillites and sandstones of the Val Gardena Sandstone (Arenarie della Val Gardena) Formation, which crop out in this narrow canyon (Maffi & Maffi, 1992).
