Water is still greenish color with steady bubbling. There is a low puddle of meltwater in Backwater Spring. The tiny creek next to the old pit toilet site is not flowing, but there is water flowing from the culvert near the picnic table. |

Water level up about 1" at first pause in F&M's 1526 eruption. Boiling maybe slightly increased over normal. Very little reaction overall to F&M. |

Water level was rising with boiling along the SW edge when I checked a few minutes into Fan and Mortar which started at 1812. The pool reached peak height around 1823, just before F&M's first pause. It was higher than I have ever seen it, less than an inch below the vegetation line on the SE corner. As soon as F&M paused, the water level began to drop slowly. |

Water level rose significantly during Fan and Mortar's eruption, nearly to the level of the vegetation around the crater. This was accompanied by heavy boiling along the southwest rim which ranged from a few inches high to stronger surges reaching 6-12 inches. This is the most I have seen from "Norris Pool" in at least a decade. |

{Spiteful 0000 contd.} Norris Pool leaves a mud surge around the rim, observed today boiling violently through the muddy water; same color as Spiteful; it had been thick mud. |
