Why are you reporting this puzzle?

Have you ever been under a bear? No? This is what it looks like.

The Capo d'Orso (Cape Bear) itself and the area around it is one of the hits of Gallura. Up on a hill, it has been used as a navigation point for centuries, though it is difficult to get a good view of the entire bear if you come by road, so let's leave it to the pros (see below).

Just to see the famous bear from a distance, take a look at these internet sources:

*********************

The Bear Rock

The erosive action of weather phenomena acts in a selective way. In fact, these phenomena not only act differently on different types of rocks, but also on various parts of the same rock, accoding to its major or minor resistance to weather conditions, thus giving the scenery a great variety of different, fascinating details and having determined the formation of this natural monument: the Bear Rock.

During different geological eras, granite has been attacked by weather phenomena, mainly marine spray and wind, but also by ice of quaternary glaciation, thus being shaped into two forms of primary evidence: tafoni and rounded rocks.

The Bear Rock belongs to the first category, the tafoni, which are formed in the open air by the dynamic action of the wind combined to that of the chemical corrosion.
Warm wind bores into rock pores, thus accelerating the evaporation of salty water and causing the deposit of salt crystals which expand exerting a pressure on the rock and causing its decay.

Thes phenomenon, called honeycomb or alveolar weathering, is visible everywhere, particularly under the Bear's head, in the upper part of it. With time the hollows grow upward thus causing the exfoliation of the vault. Tafoni can appear in the form of small holes or wide cavities also called exfoliation niches.
