During the same expedition began the exploration of the virtually unknown southeastern part of the area, resulting in more than 40 new caves (including A-30), mostly shallow ones. Only A-11 (Pozu del Porru la Capilla) offers some prospects. Its exploration ended with an accident at the depth of ca. 120 m. During a violent rise in waterflow Piotr Kolodziej died. After the rescue operation, the members of the expedition decided to postpone exploration and come back to Poland. The cave was explored to about -180 m. In the same year members of Speleo Club de la Universidad Politecnica de Valencia (SCP) discovered Sima Parodia (SCP) and attained in it the depth of ca. -38 m. Cavers from OUCC made a connection

of Pozu los Perdices (F7) with Pozu Jorcada Blanca (F2), resulting in the Sistema Jorcada Blanca (F2/F7). 1985 The drama of the former expedition dissuaded members of SG from the next expedition to the Picos. Meanwhile, members of SCP made the connection between Sima Parodia (SCP 111 ) and Sima de Cembavieja (Cem.), which results in a system of a total depth of 810 m. They also attain -157 m in SCP 134. Cavers from OUCC attain -452 in Sima Conjuarto (1/6). They also explore Pozu del Redondo (F-20) down to -382 m and 2/6 to -80 m. 1986 Continues the exploration of Pozu del Porru la Capilla (A-11 ), undertaken by Sekcja Taternictwa Jaskiniowego Czestochowa (STJC). At the depth of -400 it becomes clear that this may be another deep cave in this part of the Picos. Another Polish expedition, from Katowicki Klub Speleologiczny (KKS), acting together with the members of SCP attains, among others, the depth of -240 m in SCP 134. In the British zone, cavers from OUCC connect 2/6 with Sistema Conjuarto, resulting in Sistema Conjuarto, where they attain -655. In Pozu del Redondo (E20) they attain -582 m. 1987 Several years of exploration in Pozu del Porru La Capilla (A-11) finally brings about the long expected results. This time the success belongs to an SG expedition. They reach the final sump at -863 m. 1988 The next expedition by SG is a systematic search for new, high entrances. About one hundred new entrances were located, even in the apparently well searched zone G (among others G-13).

At the same time exploration in Red de los Barrastrosas was undertaken, showing possible leads. 1989 The rosy exploration prospects drew two expeditions from Poland: an SG expedition aiming at further exploration in zone A and an expedition of Sekcja Grotolazow Klubu Wysokogorskiego Wroclaw (SG KWW), intending to work in zone G. The small SG expedition explores A-30 to the depth of -245 m. At the same time the big expedition of SG KWW searches zone G. They mark ten new caves of small depth, visit most known caves in the zone and confirm the open possibility of advance in Red de los Barrastrosas. The main achievement was the exploration of G-13 down to 429 m. The farther activity was arrested by the accident of Wieslaw Smigielski.
