A Bright Red Lake in France

A lake in Camargue in southern France has been the source of amazement as its once blue waters suddenly turned a shocking shade of blood red and orange. Scientists explain that a phenomenon is the result of high salt concentration. Russian photographer Sam Dobson documented the event, reflecting: ‘Every small branch is covered with crystals. with the red water as a background it looks like something extra-terrestrial.’ According to researchers the colour is the product of “a salt-loving organism called Dunaliella salina”. “They produce a red pigment that absorbs and uses the energy of sunlight to create more energy, turning the water pink.” Salt crystals have formed atop plants, rocks, sticks, and any other surface in the lake. Culinary aficionados may be familiar with the area as the home to ‘riz rouge’, Camargue red rice, whose colour is likewise the result of the high salt content of its growth habitat.
