Wilson Bentley was the originator of the well-known saying that no two snowflakes are alike, yet on page 43 of his book, Snow Crystals, the top two snow crystals in the center column are very much alike. But before we run up the flag and proclaim loudly from the rooftops that Bentley was wrong, take a close look at these two crystals. They are alike because the same photograph mistakingly was used for both of them, though the upper photo has been rotated 60 degrees clockwise from the lower one. How do I know this? Look at the smudge mark on the outer left-hand side of the lower photo. The same smudge mark appears on the upper photo, though it has been rotated 60 degrees clockwise on this photo. Other artifacts on the lower crystal can also be found on the upper one. So put the flag away. Bentley's famous saying is still true.
