People have seen icy puddles before. I grew up in northern Illinois, where icy puddles were the norm in late autumn. In fact, an icy puddle in January is the usual in many parts of the world. So forgive me for showing you this picture of something you've seen a million times.
But an icy puddle at Hahamongna Watershed Park in Pasadena, California on January 13th, 2013 at 1:27:08 pm is momentous. A record should be kept. A notation must be made. This should be posted, publicly, for future generations to see in some archive somewhere.
You will not be surprised that upon our return an hour later, the ice was gone.
