A cross section of the chimney cultured for microbial studies.

A cross section of the chimney cultured for microbial studies. The exterior rinds of silica tell us temperatures were likely <70°C (~160°F), where microbes could survive. At the interior temperatures up to 240°C (~460°F) were recorded from the venting fluid - which would preclude any microbes surviving in the interior conduit.
