   This hole was found as a recent collapse in the streambed at the base of a normally dry waterfall. A 10m pitch followed by a 2m drop ends at a narrow rift choked with riverbed sandstone cobbles. There is a very strong draught but it is not worth digging in a flood-prone riverbed. The site is over a collapse down an aven just before the last pitch in El Cubillón, site 2538.
