The Matienzo Cave Project is exploring an area around Matienzo in Cantabria, Spain. The aim is to identify, explore and record the caves. This year 8 km of new cave was found in 4 sites, with a further 68 new sites identified. One of the major finds linked to a cave system we have been exploring and brings its length to over 70 km.
