0935 water level rising, parasite vent off, south pool slightly murky. after rising to overflow, the south pool had increasingly vigorous boiling and no bubbles from the parasite vent. during this time Thumping Hole was splashing to 1-1.5', and its water level rose enough to create runoff. Penta water level also up with slightly silty water |

In the duration of the 8:11 eruption, I walked up to see the two main pools bursting to a foot at most, however 5 vents in the front were going bezerk, shooting water around 2 to 3 feet in the air very rapidly. |
