Crystals on the Crick

The boys and I were playing on the ice of the frozen creek and I came across these crystals.  Tiny and exquisite.  I found some interesting ice formations in an ice cube tray once, but nothing like these.  Sometimes I wish I carried an electron microscope for images of tiny things.  That'd be better than my eyes or these images.

I did some research and found that the extreme cold we experienced caused the water in the air to condense out and build on existing crystals.  Beautiful.
