A "black smoker" occurrence. Hydrothermal waters to 302°C. Recovered from the Faulty Towers complex of chimneys (along with Fang and Roane).
The recovered portion of Finn was 1.6 m long and weighed 1,300 kg in air upon
recovery. The chimney wall thickness varied from 5 to 42 cm along the length of the structure. The central conduit of the chimney was approximately 15 to 25 cm wide.
