A low opening in a vegetated pit behind and to the southwest of the main resurgence (with the obelisk) at El Rincón. A obvious wall can be seen across a pool of still, clear water.
A proper inspection occurred in December 2019 when Martyn Grayson, in out-of-depth water, found small underwater fissures bringing in water opposite the wall, but these are not passable. "No future prospects remain."
