Snow Falls like Ash

Snow falls like ash from fires,
like ash builds up,
providing warmth for flowers.
Then all that sings is light,
a winter light
too bright for eyes of humans.

Inside, deep snow is blue,
the frigid blood of icebergs,
a brutish glow
that's only seen at poles.

And there, there are no flowers:
only blossoms of glacier-calved icebergs
and bloom of snow.
