Capped Columns
Capped Columns start out growing on their own, then they switch. Plate-growth. This happens when crystals are blown in to a region with a different temperature.
Hollow Columns
Hollow Columns are columnar crystals that are sometimes the main reason for snow falls. They are hexagonal, with conical hollow features on the end. Hollow Columns are formed at 21-14'F.
Irregular Crystals
Irregular Crystals are snowflakes that land on the ground broken, ill-formed and in bad shape. Warm snowfalls bring the irregular snowflakes, especially when wind is blowing hard.
Needles
Needles are columnar crystals that are so long and thin that they look like needles. These needles sometimes ma contain thin hollow regions, and sometimes the ends break into needles branches. Needles are formed at 25-21'F.
Rimed Crystals
Rimed crystals grows in clouds, and clouds are made of little rain droplets. These droplets freeze on to a falling snow crystal and this is called a rime. Sometimes a snowflake may just be a ball of rime, then which it is called soft hail.
Sectores Plates
Sectored Plates have ice ridges that seem to divide the plate-like arms. These Sectored Plates are flat, they are silvers of ice that fall to the earth in a stunning diversity of complex shapes. These are formed at 14-10'F.
Spatial Dendrites
Spatial Dendrites are from other individual ice crystals that get stuck together. Each branch is one arm of the Steller Crystal. These flakes are formed at 10-3'F.
