A cave perched high above the middle of the underground survey loop of Simas del Picón and Torca del Regaton. The boulder-filled entrance shakehole emitted a strong, warm draught in the winter. When excavated, the hole revealed a 10m deep drop to a slope into choked rifts. One tiny rift appeared to carry the draught.
