This is a Snow Algae sample (sample SA3) given to me to image by Thomas Beer. This is made up of 27 images of the sample magnified 800x.
I do believe so:)
I'm sorry, I meant it changed snow reddish
pink, particularly where I've seen it above
10k ft. in the Sierra Nevada. Looks like Wikipedia
had it right: "Watermelon snow, also called
snow algae, is snow that is reddish or pink in
color, with the slight scent of a fresh
watermelon. 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. Watermelon snow is caused by the
presence mainly of 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. Its specific epithet,
nivalis, is from Latin and refers to snow."
Is this the same algae you're looking at?
I'm not sure if it's the same species of
algae, the types I imaged are red and green.
However, this algae does change the color of the
snow and lives in extreme environments. en.wikipedia.org/wiki/Snow_algae&n
Is this the same algae that turns snow and
