Photo by @shonephoto (Robbie Shone) // Here is a view of the lower half of the 'Grande Salle' in Grotte de la Mine, showing a small gour pool in the foreground surrounded by a huge flowstone deposit. Discovered accidentally by mining activities last century, the chamber contains many beautiful cave formations and is home to a large colony of bats.
We're following the work of a group of scientists from the Tunisian Geological Survey and European Research Institutions (UK, Germany, Austria and SISKA in Switzerland) who are looking at changes in rainfall patterns through time. Several of their field sites lie inside Djebel Serdj, which hosts some of the largest caves in Tunisia.
