Lago Leit - Ticino - Zwitserland (2260 m.)

Pizzo del Prévat e Pizzo Meda De sneeuw was echt oranje-rood. Geen special effects ;-) The red colour might be some kinf of algae: Watermelon snow, also called snow algae, pink snow, red snow, or blood snow, is Chlamydomonas nivalis, a species of green algae containing a secondary red carotenoid pigment (astaxanthin) in addition to chlorophyll. Unlike most species of fresh-water algae, it is cryophilic (cold-loving) and thrives in freezing water.[1] Its specific epithet, nivalis, is from Latin and refers to snow. This type of snow is common during the summer in alpine and coastal polar regions worldwide, such as the Sierra Nevada of California. Here, at altitudes of 10,000 to 12,000 feet (3,000–3,600 m), the temperature is cold throughout the year, and so the snow has lingered from winter storms. Compressing the snow by stepping on it or making snowballs leaves it looking red. Walking on watermelon snow often results in getting bright red soles and pinkish pant cuffs.

The red color is partially the result of saltwater tainted with iron oxide, but the real mystery of these falls is what lives in the water. Water samples contain almost no oxygen, but at least 17 different types of alien-like microbes have been identified slithering around in the blood-like water. Scientists surmise that they survive via a metabolic process never observed in nature that utilizes sulfate as a respiratory catalyst with ferric ions, metabolizing trace levels of ancient organic matter trapped underneath Antarctica's vast glaciers.

Weet iemand van jullie wellicht waar de oranje/rode kleuren vandaan komen?
