The lithological and malacological studies covered sediments forming the low terrace of the Rogoźnik Stream in the northwest part of the Podhale Basin. This terrace is characterised by a uniform structure within a significant part of the valley. Three layers of gravel and four layers of sandy and silty muds were found there. A rich and diversified malacofauna was discovered in fine-grained sediments. Its analysis allowed us to characterise environmental conditions during sediment deposition. The age of the individual components of the sedimentary sequence was determined by radiocarbon dating. A distinct change was found in the upper intervals of the sequence, corresponding to the warm phase of the Medieval Climate Optimum. This period is associated with the robust development of agriculture, and processes related to human activities became the main factor shaping the environment, influencing the course of geological processes, and changing the taxonomical and ecological structure of the fauna and flora assemblages found in this area.

An isolated limestone hill (Cisowa Skała), located in the Podhale Basin in southern Poland, has yielded mollusc shells and small vertebrate bones in deposits filling small karst forms such as rock shelters, characteristic molluscan assemblages can be identified, the succession of which reflects changes in the environment and also microhabitat variations depending on local factors, such as slope exposure and type of vegetation. These local factors markedly affect regional environmental trends determined primarily by climate change and, during the last several hundred years, also by human activity. Such malacological analysis enables effective palaeogeographical reconstructions, both on the scale of geographical regions and for microhabitats.

The Racławka Valley is located west of Krakow, in the Krakow-Częstochowa Upland. This is a place of high bio- and geodiver-sity, where various rocks of different ages outcrop in vast excavation pits, narrow gorges or form characteristic monadnocks. The richness of various morphological forms and special habitats led to the constitution of a nature reserve, covering most of the Racławka Valley and adjacent, southern parts of the Szklarka Valley. Three educational trails lead through the reserve, connecting a number of geosites. The Geotourism Students’ Scientific Club (GSSC) from AGH University of Science and Technology examined the usability of these trails for geoeducation. After completing geotourism valorisation, adequate teaching materials were prepared, and different age groups were guided around the trails. Their comprehension has been verified by quizzes and opinions gathered through questionnaires. On the bases of these, the three educational trails were widely described and assessed in respect for their terrain difficulty, accessibility, and infrastructure. Each trail has a leitmotif and a specific theme, however geosites from different trails can be combined together to get a route of a chosen theme. The GSSC also released three new geotourism guidebooks, one for each trail, as a result of AGH rector's grant projects in the years 2018–2020.

Dolina Racławki położona jest na zachód od Krakowa, na Wyżynie Krakowsko-Częstochowskiej. Stanowi ona obszar o dużej bio- i georóżnorodności, gdzie rozmaite skały o różnym wieku odsłaniają się w rozległych wyrobiskach, na ścianach wąwozów lub w po-staci ostańców. Ze względu na bogactwo form morfologicznych i wykształcone na nich siedliska, większość doliny Racławki i przyległą, południową część doliny Szklarki objęto rezerwatem przyrody. Przez obszar rezerwatu prowadzą trzy ścieżki dydaktyczne łączące szereg geostanowisk. Koło Naukowe Geoturystyka (KNGt) z Akademii Górniczo-Hutniczej zbadało ich przydatność dla geoedukacji. Po dokona-niu waloryzacji geoturystycznej opracowano materiały dydaktyczne, a następnie po ścieżkach oprowadzono różne grupy wiekowe. Za po-mocą quizów sprawdzono zrozumienie przez uczestników omawianych tematów, a opinie zebrano w formie ankiet. Działania te umożliwiły dokładne opisanie ścieżek oraz ich ocenę pod kątem trudności terenu, dostępności i infrastruktury. Każda ze ścieżek ma motyw przewodni, można je jednak z powodzeniem łączyć, by zaplanować trasę o określonej tematyce. KNGt przygotowało też trzy przewodniki geoturystycz-ne po dolinie Racławki, po jednym dla każdej ze ścieżek, w ramach Grantu Rektora AGH w latach 2018–2020.
