What HAPPENED here? Actually, we have nature to thank for this striking sight, which is commonly called watermelon snow, and also known as red snow or blood snow! #FunFactFriday This vivid pink can be seen on the last of the previous season's snow (yes, some is still melting out!) and is actually a result of a green (yes, green!) algae. It’s part of a group called Chlorophyta, a snow algae – and is found worldwide in mountains and polar regions. As the snow melts, the algae “blooms” and develops its red pigment for sun protection. Have you seen it too? Share your pictures and tell us what you call it! Please note that watermelon snow does not taste like watermelon and can cause "digestive ailments." #NorthCascades #FindYourPark #WatermelonSnow #PNW NPS Photo/D. Mailman
