The strongly draughting, walk-in entrance (sprayed with "33" and a red dot) leads to a draughting 11m pitch. A gour-floored chamber at the base leads immediately to a greasy calcite slope where a ladder is useful. The descent ends at a chamber with avens. In 1998, the blackness noted up an aven at the bottom of the stal slope was partly bolted and led to a calcited boulder slope with a possible traverse and bolt route back over the main passage. At Easter 2000, this climb was completed at +22m where it was linked to site 1470, a 20m pitch from the surface with a small length of passage.
In 1998, a draughting calcite choke at floor level was excavated (20 years after the cave was first surveyed) and the Pearl Series entered. This is a nicely decorated false-floored phreatic passage leading to a large breakdown chamber. Pitches in the floor all choke.
