Bus de la Lum Sinkhole
Highlight • Cave
During the Second World War, the cesspool was used by partisans (the resistance was particularly active in the Cansiglio area) to dump the bodies of several soldiers of the Italian Social Republic and German soldiers, as well as civilians. Burial in natural caves has led some sources to compare this event to the Venezia Giulia (the Foibe) massacres.
According to the association Silentes Loquimur, created specifically to commemorate the victims of the Bus de La Lum, a 1949 report by the Carabinieri of Vittorio Veneto counted over 300 victims, while the speleologists of the Italian Cave Rescue Center were working on theirs Investigations in the 1960s assumed up to 500 victims (200 German soldiers, 100 RSI soldiers, 200 civilians). The same association reports that in the early 1950s the remains of 26 people were recovered, while a search carried out in 1992 turned up another 68 people who were later buried in the Caneva cemetery. No further surgeries have been performed since then due to the high economic cost.
According to Umberto Lorenzoni, president of the Treviso ANPI, "no more than a dozen skeletons were recovered" from the Bus de la Lum; and when, in the early 1990s, the president of the ANPI of Pordenone, Bruno Giust, asked for further investigations to be opened, "we were told by the president of the Victims' Association that it was not appropriate to proceed. Obviously because, in our opinion, there was nothing else to be found gave". He concluded that the Bus de La Lum was used as an improvised burial ground in the final months of the war, at a time "when nothing else could be made available".

The Gorgazzo springs have the characteristic of collecting rainwater which, infiltrating the karst structure of the Cansiglio plateau, emerges at the base of the mountain with an already considerable flow rate.

The name probably derives from "lume" or flame, due to the luminescence that would have been seen on summer nights above the cavity, produced by the gases generated by the putrefaction of animal carcasses thrown into the well. The cavity was formed by karst, or by the dissolution of the rock by water. According to legend, it is inhabited by the Anguane, very ugly fairies, with nails instead of hair, and long fangs instead of teeth. During the day they went to wash clothes at Lake Santa Croce, then wandered around in search of wood, food and children to roast. At night, they lit a small fire, whose light, spotted by shepherds, gives the cavity its name

The Gorgazzo source is an underwater cave where the stream of the same name originates, a tributary of the Livenza river. Located near Polcenigo, its name derives from the Friulian gorc which means precisely abyss. The cave consists of a resurgence and near the mouth of the cavity, nine meters deep, the statue of a Christ was placed, which thanks to the clarity of the water and the bottom is visible from the outside from the shore on sunny days .
