KHIONE (or Chione) was one of the nymphs, a daughter of Boreas, god of the north-wind, and Oreithyia, the lady of mountain gales. Khione was herself the goddess of snow (khiôn).
Some of the more famous myths featuring the goddess include:
As Oreithyia was playing by the river Ilissos, Boreas (North Wind) kidnapped her and had sex with her. She bore him daughters named Kleopatra and Khione, and winged sons named Zetes and Kalais. Latter Khione had intercourse with Poseidon, and when she gave birth to Eumolpos, without letting her father [Boreas] know, she threw the baby into the deep sea to avoid discovery. But Poseidon rescued him and took him to Aithiopia, where he gave him to his and Amphitrite's daughter Benthesikyme to rear.
Khione in Greek means 'snow.' She was worshiped all across Greece and was a favored goddess by mountaineers and hikers as they would pray for fair weather while up on mountain tops. She never had any official temples dedicated towards here.
In Roman mythology Chione is the goddess of snow and ice.
