   Photographer:  Wilson Bentley

   Summary Author:  Jim Foster

   The lacy crystal shown above, as well as hundreds of other snow
   crystals, were first photographed by Wilson Alwyn Bentley (1865-1931).
   These photomicrographs are housed at the Bentley  Snow Crystal
   Collection in the  Schwerdtfeger Library, at the University of
   Wisconsin. According to the  Lee/Magano system, this lovely specimen
   is classified as a fernlike dendrite snow crystal ( P2e). Snow
   crystals are six-sided because the water molecules that form them are
   characteristically  arranged in layers of hexagonal rings. This
   results in their stunning  six-fold symmetry.
