Scientific Speleolgogical Days, 24th edition
Each year for more than 20 years now enthusiastic cavers meet for the scientific aspects of speleology in Han-sur-Lesse for a weekend of meetings, presentations and discussions.
The scientific meeting is mainly dedicated to Belgian karst and neighboring regions, as well as to the Belgian achievements abroad. The meeting is accessible for all and is intended to be an opportunity for cavers, scientists or merely curious to inquire or submit new observations or discoveries.
On Saturday there are many interesting conferences, such as from the guest speaker Christophe Delaere from the Center for Research in Archeology and Heritage of the Free University of Brussels, who will tell us about the recent archaeological work carried out in the Lesse river at the resurgence of the Caves of Han by presenting the ancient human activities in relation to the transformations of the natural and karstic landscape and on Sunday there is a field excursion to the Fond des Vaulx in Marche-en-Famenne under the leadership of Luis Alvarez, Serge Delaby, Michel Louviaux, Georges Michel and Yves Quinif.
