Metamorphosis of Disk Plate Snow Crystal

In a valley surrounded by three low mountains in all night long stars-sky in ambient temperature of nearly -30 degrees C, atmosphere upon the snow ground became to be supersation 0%, and then the growing of snow crystal, its sublimating were simultaneously stopped, the metamorphosis phenomena made slow progress on a hexagonal plate snow crystal then. Namely, components of snow crystal were moved from one position on crystallization to other, so that the hexagonal plate with a minute stellar crystal transferred to a larger round plate with a minute hexagonal plate.
