When I looked at MT late in Fountain's eruption, it was nearly full with somw bubbling. This continued for several minutes. It began to drop gradually out of sight at 1715, about 1 minute before Fountain ended. |

Maintained a full, bubbling pool for most of this time, but if there was a follow-up eruption, the steam from Fountain and Clepsydra obscured it. |
