Today we join the UIS - Union Internationale de Spéléologie in celebrating the International Day of Caves and Karst.
The 13th of September is the date proposed for the annual UNESCO observance day, dedicated to the education, conservation and raising public awareness of caves and karst landscape. Caves truly are amazing places (we know we are preaching to the choir here), they provide drinking water, have unique biodiversity, hold invaluable geological and cultural records (and are a lot of fun). So, join us in this great celebration of caves and karst around the world.
