Pandora's box is a Greek mythological tale where Pandora opened a forbidden box, releasing all evils into the world. Loo-Wit the Fire Keeper is a Native American legend where a woman guards a sacred fire on Mount St. Helens, representing harmony and balance in nature. The key difference is that Pandora's box represents the unleashing of evil, while Loo-Wit symbolizes protection and stewardship of the natural world.
Indians of the Northwest knew the volcano as "Louwala-Clough," or "smoking mountain." Before Mt. St. Helens blew its top it was a beautifully symmetric rounded snow-capped mountain. According to one Indian legend, the mountain was once a beautiful maiden, "Loowit". This was sourced from the History of Mt. St. Helens at http://www.mountsthelens.com/history-1.html
One legend behind Mount St. Helens in Washington state involves the story of Loowit, a beautiful woman who was turned into the volcano as punishment for her forbidden love affair with a chief. Another legend from Hawaii involves Pele, the goddess of fire and volcanoes, who is said to live within the Kīlauea Volcano and is responsible for creating and shaping the Hawaiian islands.
