ramp of staircases conducts to the last visitable room of this cave: her
"Room of the Calvary Mountain", so said because, to the center, a big
deposit of rock and mud forms a hillock on which some stalagmites the
three Crosses seem to represent, just as on the Calvary Mountain.
On the left side of the "Mountain" there is a deposit of guano of bat that is the result of the presence of a thick colony of bats, still today present in the cave.
And' also performs a hole of airing for the exchange of air and you/he/she has been possible to measure the power of the rock sovrastante,circa 110 meters calcareous series.
The chemical composition of the air in the terminal zones is given by an accumulation of CO2 freed during the normal process of precipitation of the CaCo3; the rate of CO2 freed during the normal process of precipitation of the CaCo3; the rate of CO2 can overcome 10% and you/he/she can easily be warned by the tourist.
We have come at the end of the branch "fossil" of the cave, more over, behind a hillock, there is another brief non visitable line that tightens him in a gut of non practicable mud.
