| Comments: | Apparently no one was by Steamboat when it began. All indications were that it had had another short water phase of a few min. ~ After 20 min. the geyser seemed to be trying to return to the water phase as it would seem to choke momentarily on water. 11:40a So. Vent went into steam phase. |
