It’s not too unusual a sight during the summer months in higher elevations of Yosemite, but hikers are taking notice of rose-tinted snow.READ MORE: Sheriff: Modesto Mother, 32, Led Deputies On Short Chase With 2-Year-Old Daughter In Van

It may be August, but there is still plenty of snow and ice above 9,500 feet! This reddish colored snow is often called watermelon snow. The red or pink color is the usually green algae's natural sunscreen, protecting itself from too much heat and damaging UV radiation. pic.twitter.com/bfOSIadT4l

Chlamydomonas nivalis, officials say, thrives in the freezing cold temperatures of the high country. While naturally green, this algae owes its red color to a special pigment it has that acts as a natural sunscreen – creating the watermelon snow effect.
Of course, like with other funny colored snow (like yellow), people would be wise to not eat watermelon snow.MORE NEWS: Cold War-Era Relic Responsible For Loud Siren In East Sacramento Monday Night
