Report from R Paperiello to R Hutchinson March 21, 1990: {no specific time noted} Unusual sighting: There is a “new” vent opened a few feet below the main vent of Puff-n-Stuff. There is an obvious runoff channel coming from it which was wet and well defined but not used during the 5 or so minutes I stayed in the area. The algae mats below this opening are all dead. |
