According to Kenneth Libbrecht, "The rather unattractive irregular crystals are by far the most common variety." http://www.its.caltech.edu/~atomic/snowcrystals/myths/myths.htm#perfection Someone really need to take a look at his site and get FACTS off of it because I still see a decent number of falsities on this page. (forgive me Im new at this and dont want to edit anything)
