After an agreement with La Cambera, this site has been reserved for probable exploration at Easter 2022 by named members of the Matienzo Caves Project.

  A large shaft, explored over two trips in April 2022.

   A Y-hang was installed to overcome loose rock and mud about 3m down. The first pitch of 23m (with a rope protector about 2m down) lands on a debris cone. A 5m climb down rubble ends at a 6m rope pitch then a 3m cork-screw crumbly climb down with no way out.

   La Cambera group rediscovered the shaft in January 2023 with a GPS reading of 0449305 4804830.
