NOAA Photo Library Image - expl6490

Inactive sulfide chimneys along the pinnacle of one tall extinct sulfide spire. It is likely that these once had billows of superheated hydrothermal fluid emanating from them. They form when minerals in the hot fluid precipitate out upon contact with seawater. This is the summit of a 10+ meter high extinct chimney.
