Anavros

The river Anavros and Anaurus (Άναυρος, Ἄναυρος, Anaurus) is a torrent near the ancient city of Iolkos (modern-day Volos), flowing from Mount Pelion into the Pagasetic Gulf. The hero Jason was said to have lost a sandal in its waters, as he ferried the disguised goddess Hera across its stream.
