A very fine couple of days in the Cairngorms’ Garbh Choire Mòr and its environs, filming a piece for Channel 4. Unfortunately the Sphinx and Pinnacles patches are very small for the time of year, though they looked wonderful with red snow algae shot through them. pic.twitter.com/CBqoQw2Lu2

Blood Snow or Watermelon Snow has been found in the Antarctic & the Alps. It's caused by an algae called Chlamydomonas nivalis. It was noted as early as the fourth century BC, by the Greek philosopher Aristotle. It actually smells like watermelon.

" PINK SNOW" at Italian #alps looks stunningly beautiful..but it is not a good news for us! It is also known as "Watermelon snow". Nature is giving some last warnings to us! Hope we act now against the #ClimateEmergency.
