The entrance slopes down and then up to a short scramble up to a crawl. This ends at a 2m climb down. On the left is a continuing tight passage with echo. Beyond is a pitch from the surface and the route on the far side closes down in a small chamber.
In early May 2019, the "continuing tight passage" was excavated by slicing mud and moonmilk off the walls with a shovel. Further work here will require a hammer and chisel to remove harder calcite. More excavation occurred in August 2019.
A water trace from here to the Carrales resurgence (site 4855) was thwarted when the detector disappeared from the latter. A second test gave a "negative" result, possibly due to too little OBA or not enough time being given for the OBA to come through.
