Puez - Odle nature park.
The Puez - Odle park is particularly important from a geological point of view, as all the minerals, sediment strata and weathering forms typical for the Dolomites can be found in it.

The South Tyrolean Dolomites survived the phase of their formation, lasting between 50 and 60 million years, in relatively good condition. For this reason the Puez - Odle nature park can be seen as an "open history book of the earth."

The rocky crags which constitute the orographic node of the Sella massif and turns towards the north, through the groups of Puez and Odles, has its most extreme offshoot in the Sas de Pütia. Beyond that is the rocky range of Luson and the relief of Plose, which are of quarziferous Filladi origin, whilst to the west the porphyric rocky Resciesa juts out from the Odle. From this variety of geological structures a corresponding variety of shapes and rural aspects is derived. The typical tabular structure of the grey, uniform plateau of Puez contrasts with the slender, bold shapes of the "Pizes dl Cier", Odles, Sassongher and Sas de Pütia. This geologic variability is enriched by figures of remarkable beauty such as amphitheatres, caves, natural arches, rock pinnacles and strangely eroded shapes which, as in the case of Col dala Sonę, fill visitors with admiration and awe.
