tonneri (sandstone-limestone formations) that extend into the granitic
group of the Sette Fratelli (Seven Brothers), and eventually plunge into the
sea with their blade-like edges. Around the Gulf of Orosei, limestonedolomite
formations dominate in the Mount of Oliena (1463 m) and the
Montalbo (1127 m), with steep ravines, bare and whitish, that confer to
the countryside a moon-like aspect. Also, karstic action has carved a
number of shafts, large grottos (e.g. that of Tiscali) and caves, even
underwater ones, like the Bue Marino (Monk Seal) cave at Cala Gonone

(Dorgali). Between the mountain ranges and the plains of the Campidani
lies a hilly region divided into Trexenta and Marmilla, featuring gently
undulating landscapes that rise, with steep volcanic cliffs, into the typical
giare, amongst which is the prototypical one of Gesturi (between 500 and
600 m altitude). Other volcanic formations occupy most of the northwestern
part of the Sardinian region. Thus, overlooking the plain of
Oristano are Mount Arci (812 m) and Mount Ferru (1050 m), which,
connected to the central massifs through minor mountains, can be easily
crossed only at the saddle of Macomer (530 m), thus dividing
geographically the Island into Capo di Sopra (or Sassari’s) and Capo di
Sotto (or Cagliari’s), with important consequences even for human
settlement. North of Macomer, the Logudoro region bears clear traces of
its past volcanic activity, as in the eruption cones found especially between
Romana and Cheremule. The volcanic landscape extends up to the
Anglona region, making room, towards Sassari, for a vast plain nestled
amidst round-shaped hills and reaching the sea with evocative
promontories (e.g. Capo Caccia).Isolated from the other formations, the
