The snow crystal (Snowcrystal 2018.2.07b) was collected on February 7, 2018 at 11 am. Using Magano and Lee (1996) this snowflake is classified as P1a, which is a hexagonal plate. The growth of the snow crystal (and its resultant morphology) was controlled by weather conditions during its decent in the atmosphere. The following atmospheric conditions are recorded by this snow crystal: a) snow crystal in the form of a hexagonal plate, formed due to b) transitional thermal limits of -12 degrees Celsius to -9 degrees Celsius and c) a temperature of approximately -15 degrees Celsius in moderately saturated conditions. Basically, this snow crystal records the chaotic series of events from deposition of water vapor on a nucleus (e.g., dust particle) to collection. . The symmetry of this snow crystal indicates that it was formed in an environment with very stable conditions that caused faceting of the faces, giving the crystal its plated morphology.
