Watermelon snow

This phenomenon is common during the summer months in Sierra Nevada...but not in Spain...in California!! And in altitudes of 10.000 to 12.000 feet (3.400-3.600 metres).

When you walk, you leave a footprint that seems watermelon pulp and it has the smell of watermelon as well!!

But how can this happen?? And why?? It happens when a specific red-pigmented algae (Chlamydomonas nivalis) that contains clorophyll is combined with the snow that is starting to melt because the temperature is hotter. Due to this specific circumstance, snow becomes pink. Isn't it amazing??
