The Cansiglio Forest hides a myriad of sinkholes, pits, and swallow holes of all sizes, due to the karst morphology of the territory: the rain dissolves the limestone rock, slowly but inexorably forming these natural chasms and fissures on the ground. The Bus de la Lum is an abyss characterized by a single large vertical entrance shaft 180m high, which then develops into a very large and articulated underground complex. The depth of the shaft is best appreciated out of season, because in summer the lush vegetation tends to partially obscure the view. According to ancient beliefs, it is the dwelling of the Anguane or Anduane, fierce and evil witches, toothless, with long rusty nails instead of hair and sharp fangs, who kidnapped and ate children! They gathered at the bottom of the cave, lighting fires, whose glows rose to the surface, visible at night to the shepherds of the area: hence the name 'Buco della Luce' (Hole of Light). In reality, the legend has a grain of truth: on hot summer nights, will-o'-the-wisps could indeed be formed by the decomposing carcasses of livestock dead from illness, which it was customary to throw into the Buso. During World War II, the cavity was sadly used by partisans as a foiba, to dispose of the bodies of fascists and nazis, but also of civilians: over the years, several bodies and bones have been found during explorations. https://it.wikipedia.org/wiki/Bus_de_la_Lum

The dinosaur footprint found near the Buga del Figariol, on the Cansiglio plateau, represents one of the most significant paleontological discoveries in the Veneto-Friulian Prealps. The footprint is impressed on a grey limestone boulder located near a sinkhole and dates back to the Early Cretaceous, about 120-125 million years ago. The track belongs to a bipedal carnivorous dinosaur, probably a medium-sized theropod, about five or six meters long. This evidence has revolutionized the geological understanding of the area: its presence demonstrates that the ancient carbonate platform was not entirely submerged, but featured stable emerged lands that allowed large reptiles to pass. Immersed in the suggestive wooded context of the Cansiglio, the Buga del Figariol footprint transforms a quiet hiking trail into a journey through time, documenting a prehistoric ecosystem radically different from the current mountain environment.

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
