   This site was originally described as "an undescended 6m long, 5m deep rift surrounded by a fence." It turned out to be more interesting when investigated in April 2018.
   The shaft splits. On the uphill side, the route drops 5m to a rift with a sloping floor followed for 5 - 6m to where it becomes too tight at a possible dig. The downhill side descends 12m to a choked floor. To one side, through a hole in the choke, the top of a pitch is reached. This has been estimated as possibly 150m deep.
   In early June 2018, Phil Goodwin reported that the Pistruellos group, after some complicated rigging where the shaft bells out, were down 90m but with no sign of the bottom. The group "hope to finish it in the next couple of weeks or so".
   After meeting with Miguel and Pedro, 24/5/2019, it emerged that exploration down the pitch had been foiled by broken drill bits and that G. E. Pistruellos hope to continue exploration later in the year.
