After attempts to find the cave (at a wrong grid reference) in August 2016, the entrance was finally re-located and GPS'd the following November.
A small entrance under a scar leads directly onto a steeply descending calcite slope with columns. The route down ends on rubble then a flat mud floor with drip pits. To the right (south) is an impressive, isolated 4.5m high column; the wall behind and some stal have been plastered with carbide(?) graffiti. Around to the east, is a toppled stumpy column which has rolled and has later calcite growing on and around it.
The "60m diameter" chamber, according to the entry in reference L75, may have a way on which has collapsed. Further investigations in 2000 found no such prospects, although there are small routes which may repay closer inspection. A thorough (re)inspection and resurvey was carried out in August 2017 - 2019. At this time the length of the cave was calculated as 180m - the sum of the lengths of the chamber's major and minor axes.
Site 4599 may have been an entrance further northeast at one time as daylight was spotted (4/8/17) to the north of the main entrance.
Members of the Matienzo Karst Entomology Project on a visit at Easter 2019 found no sign of bug life and saw only one lesser horseshoe bat.
The site is well worth a photography session!
