What I wouldn't give to play around with one of those, if only for a little bit!
Amazing views! Thanks for adding those!
From your link, I went to see what SEM stood for and ended up here:
National Snow and Ice Data Center
http://nsidc.org/cryosphere/snow/science/formation.html
Once snow crystals form in the atmosphere, they grow by absorbing surrounding water droplets. The snowflakes we end up seeing on the ground are an accumulation of these ice crystals.
This magnified image of snow crystals was captured by a low-temperature scanning electron microscope (SEM).
The pseudo colors commonly found in SEM images are computer generated, and in this case highlight the different flake formations.
