Location

La Cerqua locality. From the Narni Scalo junction, take the SP29 Via Capitonese northwards, towards Sambucetole. After about 100 m, turn left along Strada Amerina, now a drovers' track, which descends steeply towards the ditch. You can leave the car at the edge of an olive grove; from here you descend into the ditch following the trails beaten by wildlife. Once at the watercourse, follow it downstream until you see the conglomerate scarp in which the cave opens. Path passable. Free access. Setting of the entrance: rural, scarp.

Description

Morphology

The only passage, opening in the conglomerate at the level of the ditch. Horizontal trend. The entrance is a narrow fissure adjacent to other openings which, however, are clearly wild animal burrows; all of them open at the foot of a bank of conglomerates (puddingstones) about 4 m high along the ditch.

Progression

Easy traversability; recommended period all year round.

Other details

Pollution: solid waste, low intensity; presence of an accumulation of abandoned concrete vine stakes at the foot of the scarp close to the entrance. Geology: ASC Clay, sand and marine conglomerates (Pliocene); conglomerates or breccias; not stratified, massive, obliterated.
