| Note: | After aborted eruption, the Grotto system went into a stalled pattern. Grotto Fountain was in a continuous boil up to 2 ft ( mostly 1 ft and under) from 17:49 to 19:28, 19:34 to 1943, and 19:51 to 19:58. The “pressure pool” was rising and falling just barely in and out of view from 17:20 to 18:51, then staying always in view until Grotto Fountain finally erupted at 20:09. Grotto was silent except for three one minute grumbles during this time. All Spa vents were off and the pool rose only 3 inches during this time. |
