The "Settsas" massif is a milestone in the history of geology, as it is one of the first explored areas in the Dolomites and is also called the "Richthofen" reef.
The name derives from Baron "Richthofen" who, interested in the geology of the Dolomites, discovered in 1800 that the "Settsas" is nothing other than a coral reef. This mountain is very important from a geological point of view because it preserves the geometry of two reefs from the Triassic period (23 m.a.) with the fossil underwater ramps and the connection with the deep sea deposits that surrounded them, the " S.Cassiano" formation.
At that time they were in tropical latitudes and thanks to plate tectonics they have moved to where we see them now.
The researches of Baron "Richthofen" had fundamental importance, as much as they allowed to give bodies to the tectonics of the plates, according to which the parts of the rocky crust that cover the planet can move, in the geological ages, even of thousands of kilometres from the place where they are formed.

The tour in numbers
From here, continue on the "CAI" path no. 23 and between the rocks you can see the "Col di Lana" mountain more and more clearly.
For the clockwise route, go from the "Valparola" Mountain Hut towards the small lake and take "CAI" trail no. 23 and then return on "CAI" trail no. 24.
