  Following a cold draught from above the entrance to El Cubillón, this shaft is reached by traversing to the left of the Cubillón entrance ("about 25m above"). It "comes out of a rift back into daylight after 10m in a rift 6m to the left of El Cubillón". (The source of the draught could not be found when first explored.)
