Crystals lose their points due to molecular motion, wind, and direct pressure.

The crystal arms are broken and then rounded grains fuse by freezing into larger crystals in a process called sintering. Crystals lose their points due to molecular motion, wind, and direct pressure.

Crystals lose their points due to molecular motion, wind, and direct pressure. Physically breaking the snow crystals, for instance stomping on them or disturbing them with a shovel, will produce the same effect. The crystal arms are broken and then rounded grains fuse by freezing into larger crystals in a process called sintering.
