Itineraries
screes and alluvial fans dating back to upper Pleistocene-Holocene (0.8 Ma
onwards). These terraces are often bordered by steep and jagged sea cliffs,
elsewhere are lower, intermingled with little pebble beaches and bordered
by living biostructures called trottoirs. The only sand beaches of the area
are located on the island of Favignana and in the bay of San Vito Lo Capo.
Mt. Cofano belongs to the Mt. Sparagio-Mt. Cofano Unit (lime-
stones and dolomites), while the Mts. of Zingaro and San Vito Lo
Capo belong four different lithological units mostly made up of lime-
stones; among them, the unit Mt. Speziale-Mt. Palatimone is particu-
larly rich in karst morphologies (deep fluvio-karstic canyons, vertical
cliffs, sinkholes, etc.), while the unit Mt. Acci-Pizzo di Sella contains
also marls, radiolarites and argillites, which occur in the four litholog-
ical units of Marettimo as well. Not surprisingly, most of the springs
and dripping sites are concentrated in these latter lithological units.
Mt. Sparagio (1111 m a.s.l.) and Mt. Inici (1066) are the highest
Mounts of Trapani; several peaks located in the Zingaro reserve go
beyond 800 m (Mt. Speziale: 911, Mt. Passo del Lupo: 867, Mt. Acci:
829) and together with Mt. Cofano (657 m s.l.m.), Mt. Palatimone
(595) and Mt. Monaco (529 m s.l.m.) dominate the small plains of Cas-
telluzzo and San Vito.
