In search of red snow https://microscopesandmonsters.wordpress.com/2025/01/26/in-search-of-red-snow/
"#SnowAlgae have been known for a long time – the earliest records of #RedSnow are from the alps in the late 18th century, and they were first recognised as #algae about 40 years later when an expedition was exploring the North-West passage. There have since been records from all over the world... snow algae have a window of opportunity in spring when the snow starts melting, and there is both sunshine & water which they can use to photosynthesise"
