An impressive arched entrance, some 30m wide that enters a rocky chamber 40m long. An old remnant with several low phreatic inlets with avens.

Various digging sites have been excavated and these are highlighted and lettered on this survey. The draughting crawl at the end of the cave has been excavated to a split and is still going (A). This was further pushed in November 2005 to where the passage dips down and splits into 2 very narrow ways on - "too small to even dig".
A better possibility may be a rift in the floor of the chamber where boulders need to be removed (B). In 2003, some boulders were removed and digging also took place under the main aven inlet in the main chamber (C) where the floor slumped in, and at a slot to one side (D).

The cave, and the valley, lies some 70m above Eye-glasses Passage and a series of inlets in the Sumidero de Cobadal.

A sediment sample was taken in 1994 (down to the right of the main chamber).
