The snow on our deck railing is hanging down about 3 feet in a "U"
shape. How can snow hang like this without falling? Where can I find
out more about this?
Well, ice has no trouble hanging down great distances, right?
And snow is made of the same stuff as ice...
Of course, snow is much more weakly bound together, but there
still is some binding between the little ice crystals that make
up snow, and enough (with the right kind of snow) to sometimes
allow the snow to form overhangs.
