Summary AuthorJim Foster

This breathtaking snow crystal was photographed by Wilson Alwyn Bentley (1865-1931) over a century ago. Along with hundreds of other such photomicrographs, it’s housed at the Bentley Snow Crystal Collection in the Schwerdtfeger Library, at the University of Wisconsin. Based on the Lee/Magano system of classifying snow crystals, this exquisite specimen is labeled as a dendritic crystal with sector-like ends (P2d). Despite its numerous convolutions, it’s nonetheless 6-sided, exhibiting classic six-fold symmetry.
