As part of the celebrations marking the 80th anniversary of GeoZS, we hosted the exhibition “The Microcosm of the Karst: Shapes and Colors Captured in Rocks” at the Gallery of the Faculty of Education at the University of Ljubljana. The exhibition was created as part of the Interreg IT-SLO project Joint management and sustainable development of the Classical Karst area. The photographs on display took visitors on a journey into the wonderful world of various types of rocks from the Karst region, as seen under a microscope.
