'Watermelon snow' spotted on US glacier
The Grinnell Glacier in Montana, US is witnessing a phenomenon called 'watermelon snow' wherein the melted snow in the area appears red in colour. The phenomenon is caused by a particular kind of red-pigmented algae known as Chlamydomonas nivalis, which contains a pigment that creates bright red hues after combining with snow. Interestingly, 'watermelon snow' has a light sweet smell.
