The largest sulfide chimney ever found was from the Juan de Fuca Ridge. It stood 47 meters high and was named Godzilla by the scientists who discovered it. Godzilla collapsed into a heap of rubble in 1996, but by the next year, a second spire, about 20 meters high, had grown in its place. Great amounts of mineral-laden hot water must circulate in the crust for such massive structures to form. About 80 percent of the Earth’s internal heat escapes through the ocean ridge system.
The sulfide chimney displayed here were named for charaters in Irish mythology: the warrior Finn MacCool, Gwenen, Guinevere’s lusty sister, and Roane (Gaelic for “seal”), one of the fairy people.
