As this engrossing site from the National Science Foundation (NSF) website notes, most ecosystems in the United States depend on snow. Whether it is the aggregated snowpack that feeds into the rivers that sustain our agriculture, or the spring flowers that need the nutrients that come from snow to thrive, heterogenous components of our geographies need the winter months. On the site, various articles unpack the wonders of snowpack. For instance, A Conifer's View of Snow, which is one article in an eight-part series, tells the tale of how an NSF-funded research team used trees to measure and predict moisture in the High Sierras of California. Meanwhile, Nature's Igloo explores the wonders of the subnivium, the snowbound refuge that many creatures use to insulate themselves from the cold.
