Underground Description

From the Quelli entrance, pitches p8, p19, p83, p33, p24, p17, p5, p33, p24, p9, p33, p27, p103 lead to -400m. Here one reaches a vast passage going up and downhill. The downstream passage emerges at the top of an 84m pitch. Below this a winding canyon interspersed with small pitches gives onto a 15m pitch and the end of exploration in 1976 at -708m.

The lower entrances lead by large phreatic passages to pitches which drop into a further large horizontal level which undulates between -410m and -500m. At -497m, this links to the main vertical system from Quelli. Using these lower ways in, exploration reached a sump at -913m in 1977. Following the large phreatic level away from Quelli goes for about a kilometre before breaking into the side of a colossal shaft at -414m. This is a 211m pitch to a choke at -625m. There is a possible way on across this shaft, which is, however, 20m in diameter.
