The
Bussento Caves at the town of Morigerati are
a series of karst
caves and passages along the Bussento river
in the southern part of the Cilento and
Vallo di Diano National Park in
the province of Salerno. After
Morigerati the river then flows south into the
gulf of Policastro about 7 km away near the
town of Policastro Bussentino. The WWF
Bussento Caves Oasis in Morigerati is 600
hectares (1500 acres) in area. The Bussento
river, itself, is 37 km long with a
hydrographic basin of 352 km² (136 mi2).
It starts at 900 meters a.s.l., about halfway
up the slopes of Mt. Cervati, the highest
mountain in Cilento (and second highest in all
of Campania). The river starts at the spring
of Varco di Peta in the town of Sanza, flows
for 20 km into the artificial (from the damm
on the Bussento) Lake Sabetta, picks up flow
again and near Caselle in Pittari at a point
233 meters a.s.l. drops into a large swallow
hole* (Inghiottitoio) and passes
beneath Mt. Panello, remerging after 7 km at
Morigerati. After picking up the waters of the
smaller Bussentino affluent, the river flows
to the sea. The point at Morigerati where the
river flows back up from the underground to
the surface is where this grand series of
galleries and passages begin. That is where
you start to "explore the resurgence" (as the
Italian phrase has it). There are still
unexplored points of the caves, such as
underwater sections (called siphons or
sumps) and these areas are of great
interest to scuba-cavers. The sections that
have been incorporated into the oasis are,
however, quite visitable, and the WWW offers
guided tours and workshops. The non-cave parts
of this WWW site also offer a great variety of
flora and fauna. The oasis has been in
existence since 1985.

*note:
Although common usage tends to use
"sinkhole" for almost any hole in the
ground, there is a geological difference.
A sinkhole in karst areas is a saucer-like
hollow in the limestone surface caused by
solution —that is, chemical weathering in
which solid material is dissolved in
water— or rock collapse, thus allowing
further solution and further collapse.
Sinkholes may then allow water seepage
into underground drainage areas. (In urban
usage a sinkhole is a surface collapse
caused by underground movement of water
usually from broken water or sewage
lines.) A "swallow hole" (also called a
"ponor") is a point on the surface at
which a flowing stream meets permeable
rock and is channeled into an underground
drainage area, thus disappearing from the
surface until it reemerges at a certain
point to continue as a surface stream.
