Originally, the EUGEN was to happen in Ljub- no ob Savinji. During the last year we were prepar- ing for the event and spent a productive weekend at the Kamp na Otoku in Ljubno ob Savinji. Previ- ous two EUGEN meetings in Slovenia happened in 2003 and 2014, both located in western Slovenia. Therefore, we focused on eastern Slovenia, where we prepared field trips to present mining in this part of Slovenia, igneous and metamorphic rocks of Pohorje massive, as well as karst geology and geomorphology in Logar valley and Snežna cave. Unfortunately, due to the heavy flooding in the beginning of August we had to change locations on very short notice. With great help of the local fire department (PGD Zavrh, Pokojišče, Padež) we moved to Zavrh pri Borovnici. With quick thinking we provided and arranged food, drinks and trans- port. With help from field trip organizers there was also no lack of interesting and diverse field trips, more focused on the Central Slovenia. Even with news of the floods spreading to other countries, there were still more than 90 partici - pants from 16 different countries (Austria, Cro - atia, Finland, France, Germany, Great Britain, Italy, Luxemburg, Netherlands, Norway, Poland, Portugal, Slovenia, Spain, Sweden, Switzerland). During the week we organized three field trip days with total of six different topics. The partici - pants had the option to learn about the local geol- ogy of Borovnica and its surroundings and paleon- tology of central Slovenia, as they visited outcrops Fig. 1. Palaeontology field trip. 311 for the Toarcian anoxic event. They also had the option to learn about the tunnel construction sites in Slovenia and flysch deposits as part of the field trip to the Slovenian coast. To learn more about the karst in Slovenia, we visited a karst cave (Križ- na jama), followed by a visit to Cerknica lake. As mining is an important part of Slovenian heritage, we organized visits to Sitarjevec mine and Velenje coal mine. Additionally, the participants learned more about geothermal water in Slovenia and op- eration of the Slovenian thermal baths in Dobrna. We also visited the Ljubljana Marshes nature park. Many researchers and professors from the Faculty of Natural Sciences and Engineering and the Ge- ological Survey of Slovenia (GeoZS) showed great help in performing and execution Geological Sur - vey of Slovenia (GeoZS) showed great help in per - forming and executing the field trips. During the week, various lectures were held in the evenings, where the participants learned about the geology of the whole of Slovenia, the operation of GeoZS and PhD Baltic Teach project. The par- ticipants also had the opportunity to participate and present their works in the field of geology. We had the opportunity to learn about Kyrgyzstan summer school and Diagenesis, porosity and res - ervoir potential of the Karchowice and Diplopora Beds in Upper Silesia. As part of the last lecture, EUGEN e.V. presented their organization and their international cooperation. Of course, there was no shortage of fun dur- ing EUGEN’s time. Wednesday was dedicated to the Geolympic games, where participants get to mingle and compete with each other. On Saturday 12.8. we concluded the event with a cultural and geological tour of Ljubljana. Even though we struggled with reorganization of the event, facing the possibility of cancelation, we managed to organize a successful event, that attracted many new student participants from all over Europe. At the end of EUGEN week, the par- ticipants decided that the 27 th EUGEN meeting in 2024 will happen in France. The event was sponsored by IRGO Consult- ing d.o.o., Geological Survey of Slovenia, Bo-Ra- tec GmbH, Javno podjetje Vodovod Kanalizacija Snaga d.o.o., Združeni NTF, Slovensko geološko društvo, Študentski svet Naravoslovnotehniške fakultete, GIH, geologija in hidrogeologija, Judita Črepinšek s.p. and Pharsol d.o.o.
