national and multidisciplinary. It brought together clas-
sical karst and cave studies and the exploration of glacier 
caves. The 25
th
 Speleological School was a joint meeting 
of UIS and IGU Commissions and also the 8
th
 Sympo-
sium of GLACKIPR. There is a list of thematic sessions 
and field trips which were offered by this school: the rela-
tionships between glacial and karst systems; glacier caves 
and karst in recently glaciated areas; drainage systems in 
glaciers and karst - analogies and differences; cryokarst 
- definitions, analogies and relationships with carbonate 
karst; chemical denudation rates in glacier-covered and 
ice-free karst basins; evolution of karst under glaciation, 
with special reference to continental glaciations and per-
mafrost; hydrothermal activity and its influence on karst 
evolution in glaciated areas; cave sediments, fossil cave 
fauna and human traces in caves as records of environ-
mental changes in the past, with special reference to the 
Pleistocene glaciations. 
Programme of the meeting was separated into 
three parts. Part A, March 19-21 2007 was organized 
as a field trip and session in Kraków-Częstochowa Up-
land (Częstochowa Plateau) and was dedicated to evo-
lution of karst under glaciations, hydrothermal activity

th
 Speleological School 
“Karst and Cryokarst” was organized by the f aculty of 
Earth Sciences, the Department of Geomorphology of 
the University of Silesia, Sosnowiec, Poland; the Zoologi-
cal Institute, the University of Wrocław, Wrocław, Poland, 
and the Scientific Committee of the Niedzwiedzia Cave, 
Kletno, Poland with the scientific support of the Commis-
sion on Glacier Caves and Cryokarst in Polar and High 
Mountain Regions (GLACKIPR) of the UIS Karst Com-
mission of the IGU. The Speleological School was estab-
lished a few years after the discovery of the Niedzwiedzia 
(Bear) Cave in Kletno. The 25
th
 Speleological School was 
dedicated to Professor Dr. Marian Pulina and Profes-
sor Dr. Teresa Wiszniowska, a paleozoologist from the 
University of Wrocław. During the School there was also 
unveiling of the commemorative plaque of Prof. Pulina 
at the Department of Geomorphology of the f aculty of 
Earth Sciences, University of Silesia in Sosnowiec. Profes-
sor Marian Pulina was a founder of Speleological School 
and co-founder of the Commission on Glacier Caves and 
Cryokarst in Polar and High Mountain Regions of the 
UIS and an active member of the Karst Commission of 
the IGU. f rom the very beginning, the School was inter-

in the past, cave sediments, fossil cave fauna and traces 
of man in caves. Excursions visited area of Kroczyce 
Hills (Podlesice - Łysak Hill - Popielowa Hill - Posrednia 
Hill - Zborów Hill (Cave in Kroczyce) of the Kroczyce 
Hills (light is necessary); and the northern part of the 
Częstochowa Plateau (karst and caves in the contact zone 
with the Odranian/Saale Glaciation ice-sheet, stops in 
Siedlec quarry - Towarne Hills - Kusięta - Sokola Hill in 
the area of Olsztyn). Part B, March 22-23 2007, was dedi-
cated to main scientific sessions of the 25
th
 Speleological 
School and 8th GLACKIPR Symposium at the f aculty of 
Earth Sciences, University of Silesia in Sosnowiec. There 
were lectures and posters of different fields of karst and 
glaciokarst research. Abstracts and Guidebook for the ex-
cursions were published before the meeting; P . Socha, K. 
Stefaniak and A. Tyc edited publication.  Part C, March 
24-26 2007, was separated in two parts, to session at the 
University of Wrocław and to field trip and session in the 
Niedzwiedzia Cave in Kletno (Sudety Mts.). f ield trip to 
Kletno and Jaskinia Niedzwiedzia was dedicated to karst 
phenomena of the Klesnica Valley, karst and caves in 
marbles, cave climate, fossil fauna with special reference 
to cave bear, old fluorite and uranium mining area; and 
field trip to the area of Radochowska Cave to karst hy-
drology, cave archaeology and fossil fauna. 
School was again very successful, there were 132 
participants from Canada, China, Czech Republic, 
f rance, Germany, Italy, Moldova, Norway, Romania, 
Russia, Slovakia, Slovenia, Spain, Ukraine and Poland. 41 
of the participants were PhD and undergraduate students 
from Poland, Czech Republic, Romania and China. Slo-
venia was presented by Andrej Kranjc, also a president of 
the IGU Karst Commission, Maja Kranjc, Jurij Kunaver, 
Andrej Mihevc, Tadej Slabe and Nadja Zupan Hajna. A 
large party of researchers from Slovenia shows the long 
tradition of collaboration between Poland and Slovenia 
in the field of karst research.
