Sinkholes
Credit
: Benjamin Musella - PNR Queyras
Description
The sinkholes are circular depressions in the ground. The disintegration of surface limestone (reference made here to gypsum) causes a weakening, leading to its collapse which may be slow or sudden. Their bottom, often waterproof and rich, promotes the development of vegetation. It is advised to be careful going into this "Swiss cheese".
