"It is thought that Qaqa Mach'ay is an abandoned glacial sink formed on a geologically-favourable bedding plane. Its enormous entrance, approximately fifty metres long, thirty metres wide and fifty metres deep, leads to a square-shaped descending passage twenty metres high and twenty metres wide. Although this large passage is almost completely blocked by boulders, two possible continuations were noted.
