The splendid Larieto larch forest is a large expanse of pure larch covering the slopes of Pomagagnon. It is a beautiful example of a wood pasture, a cultural practice that is still in use in some rural areas of the Dolomites, especially on the sunny slopes, and which creates different natural landscapes, each with its own cultural and historical importance.

The mountain groups surrounding the Ampezzo Valley have a sequence of rocks (over 3,000 metres thick) which covers a period from 270 million to 25 million years ago. Here the structure of the ancient archipelago of Triassic islands, the original geometries of the islands with their inner lagoons and the relationship between the islands and the deep-sea sediments that surround them are clear to see.
