ca -230 m. The cave was considered unpromising for further exploration.
Surface prospecting was done in zone G and near Jou de la Canal Parda,
Jou de Arenizas and Jorcada Blanca. Despite searching many earlier known
and newly discovered entrances, no significant depths were achieved.
The area of prospecting was extended in 1998. In zone G, caves discovered
in the 70ties by SCOF on the slopes of the La Asunciana were explored.
G-1 (-190) was communicated with the small G-6 and possibly with Red de
los Barrastrosas (G-7/G-4/G-5; - 315 m). The higher lying entrance G-1
raised the total depth of the system to 322 m. Exploration in the Red
de los Barrastrosas did not bring remarkable results.
Zone A also revisited was. Little progress was made in the exploration
in Pozu del Porru la Capilla (A-11; -863 m) in a series at ca -250 m and
in caves on the NW slopes of the Torre de los Traviesos. Exploration was
also attempted in Pozu de los Garapozales (A-3), explored by SCOF probably
to ca -60 m. The depth of 432 m was reached at the bottom of a nearly
100 m deep shaft choked with fallen rocks.
Dye-tracing was the main activity in 1999. The aim was to study the drainage
of Sistema del Jou de la Canal Parda (A-30/A-25/A-24/A-1; -903 m, that
is 1312 m above sea level), Pozu del Porru de la Capilla (A-11; -863 m,
that is 1285 m a.s.l.), Sistema Conjuarto (1/6, 2/6; -658, that is 1341
m a.s.l.; in the zone of the Oxford University Cave Club) and Sistema
del Canalon de los Desvios (F-18/F-17/F-15; -542 that is 1312 m a.s.l.).
The final, drowned series of these caves lie beneath the cirque Joon de
los Desvios, where waters drained by these systems may join and be drained
farther. Pozu del Porru la Capilla (A-11; -863 m) was selected for the
experiment. The outflow was expected in the Río Junjumia, Río Redemuna
and Río Casano. The positive result was obtained only in the Río Redemuna.
After the dying, exploration was attempted in Pozu del Porru la Capilla
(A-11; -863 m). The entrance at altitude 2148 m was discovered by an expedition
of Speleoklub Gliwice (SG) in 1984. Exploration was then ended by a tragedy
at ca -180 m. Two years later the cave was explored to ca -400 m by an
expedition of Sekcja Taternictwa Jaskiniowego Czêstochowa (STJC). The
final lake at - 863 m was reached in 1987 and the cave has been not explored.
One of the most interesting places in this cave was the final lake. However,
attempts at exploration proved unsuccessful. Similarly ended exploration
of other high-lying entrances in zone A.
Dye tracing was done also in 2000, this time in zone G. The only, though
not a good one, object for dying was G-13, 429 m deep (ca 250 m above
the expected base of erosion at Gueros de Junjumia). The Río Junjumia,
Río Redemuna and Río Beyera were selected for observation. The appearance
of the tracer, however, has been not confirmed in any of the streams.
Despite the earlier negative opinion, an exploration reconnaissance was
attempted in the final chamber of G-13 already during the preparation
for dying. After the dying, further action was undertaken, though at no
avail. A few alternative entries were found into the boulder chock at
the bottom of the chamber, but none of them was pushed for more than twenty
metres. Possibilities above the chamber were also tried with a negative
result. This cave, unfortunately, has to be considered as lacking prospects

A renewed attempt at exploration was made in Pozu del Porru de los Garapozales
(A-3; -432 m). The exploration goal in this cave was to bypass the final
hundred-metres shaft. After a traverse above the shaft a possibility of
descent appeared. However, despite of using long HSA anchors, we could
not rig for a safe descent. Because of the high risk, exploration was
In zone F, exploration was made in Sima de los Desvios (F-3; -323 m).
The main goal was to resurvey it and make an exploration reconnaissance.
For the lack of any leads, no exploration was undertaken. Exploration
behind a nearby entrance (F-3B) resulted in communication with the main
series at ca -70 m.
Reconnaissance was continued in Red de los Barrastrosas (G-1/G-7/G-6/G-4/G-5;
-322 m). The most interesting problem for all parties exploring in this
complex system was Wielki Meander (Big Meander) in the final series, at
- 315 m, with exceptionally strong draught. After getting to the bottom
through entrance G-5, an attempt was done at exploration. Unfortunately,
the problem lost its importance as the strong draught disappeared. It
may be supposed that it was the great mass of ice in the higher Sala Lodowa
(Ice Room) which caused the draught. When the ice melted out, there was
no more cold, heavy air to be pushed into the lower series.
The last four years of Speleoclub Wroc³aw's activity may be considered
successful, despite the lack of spectacular achievements.
