Photographer Anatoly Beloshchin’s photo series of Cenote Angelita (‘Little Angel’) in Mexico’s Yucatan Peninsula: an apparent ‘river’ in a collapsed limestone cenote cave formed by a phenomenon known as halocline.
According to Beloshchin, Cenote Angelita is fresh water until a depth of about 29m. There’s then a 1m layer of hydrogen sulphide, below which the entire base of the cave is filled with a dense layer of saltwater 30m to 60m deep.
This saltwater layer is the ‘river’.
