Between meadows, natural river springs and eruptive rocks
<p>Fontanazzo is the largest hamlet of Mazzin and borders Campitello to the north. It is even divided into two: Fontanazzo di Sopra and Fontanazzo di Sotto, which hosts the town hall decorated with bas-reliefs depicting typical activities of the past.</p>
<p>Campitello was born on the alluvial cone of volcanic and sedimentary rock debris of the Dolomites transported by the Duron stream over geological eras. The area is therefore particularly fertile and marshy with very rich vegetation. However, up to Fontanazzo, you move in a territory characterized by eruptive rocks related to a magmatic event dating back to the Middle Triassic, about 230 million years ago. This explains why it is more prone to landslides than elsewhere. By studying these rocks, it was understood that in the Middle Triassic the earth's crust broke apart allowing magma to rise, forming in Val di Fassa at least two submarine volcanoes, one in the Marmolada area and one in Monzoni-Buffaure. The Dolomites, which emerged from marine waters, have been fractured and eroded, hence they are fragile but not deformable. The rocks in this area are particularly heavy; each cubic meter weighs about 3 tons!</p>
