Surrounded by vegetation, this wide shaft looks at least 10m deep. Out of the current Matienzo permit area.

It was explored by the Colectivo Piezo in February 2020. The following account is through Google Translate:
A large torca with dimensions of approximately 15 meters in diameter by 30 meters deep, near the road and a cabin with an abandoned caravan. You can go down several places, the best place is the side of the road, which has a very pronounced ramp of leaves and mud. We descend from the bottom and through a window that connects from a parallel dolina. A ramp of leaves gives access to an almost vertical drop to the bottom. It begins by fractioning into a natural anchor for later, with three MMS anchors, progress to the end. No continuation is observed anywhere. There is only a small ascending protrusion that has no possibility of continuation. From the cave a small ramp is lowered with a lot of garbage, mud and leaves that does not go anywhere either. It is a very pretty torca, and somewhat jungle, full of vegetation, but full of garbage and remains of animals that have fallen, without any possible continuation.
