Etymology
Müšyl ([], ) means crater (disambiguation), crater in the Mari language. In early documents it was known only by its Mari name, written in the Russian text with Mari diacritics. Later, Russian-speaking tourists were inspired by the sea-like colour of the water to give it the more poetic Russian name.Popular culture
According to Mari legend, a wedding procession fell into the Sea Eye and died when it suddenly appeared in an eruption. The lake has become popular with tourists.References
