Del Roble II

The mouth of the pit opens in a small clearing of medium size and measures 0.5 x 0.5; the cavity does not widen until descending 3 m. The mouth is followed by a tube 2 m deep that leads into a joint of medium size. In its first metres the pit is a flowstone in an advanced state of decomposition, replaced at -6 m by completely washed bedrock; at the base the debris fallen during the period of opening to the surface of this cavity can be seen. Its narrowness, with a mouth cut in clayey material and Sand, demonstrates its recent formation (opening).

The lithochemical formations are barely perceptible.

The function of this cavity as a sinkhole is clearly observable.

Descend through the joints for 10 m, after which the pit ends in a platform of 3 x 4 m. At this point a narrow lateral joint can be seen, which is followed for 4 m until reaching a small shaft that ends in a small sinkhole clearing.
