   A portion of major passage now half filled with sediment and calcite. The cave is about 18m wide at its widest point and chokes with calcited debris and sediment. Digging possibilities were investigated at the start of 2007 but the site is seen as a long-term effort. The main passage length is about 60m. Down on the right at the entrance, past high tension cable insulators, a small discrete passage heads south for about 15m but becomes narrow with calcite. This was excavated early in 2007, following a draught, and linked with site 1403 near the pool at the base of the entrance slope. The link was surveyed in 2018.
   Also in 2007, various bones and pottery were documented. An annotated survey positioning these items can be seen here. Pieces of black pottery found in an eroded stal basin about half way along the north side of the main passage have similar marking to a series of pots from Cueva AER in Soba.
   In 2018, a small passage was entered to the northwest of the entrance, photographed and surveyed to form part of a re-drawn survey.
   Bats were seen roosting in December 2009.
