Twin has much less water in it than it had a couple of weeks ago. The water level is now nearly out of sight. |

Water visible near the bottom of both craters. Each is boiling lightly. Facing the lake, the right vent has a more vigorous boil than the left. |

Heavier boiling seen than on my last visit (last month) with small splashes from the left vent - bubbles still rising in right vent. Water level still below the clump of grass hanging on the side of the right vent. |

Twin has warm water about 12-15 inches below overflow. The southern (right hand) vent is bubbling but likely not boiling. The water is opalescent. |

Can't improve over yesterday-s report except I would have called the left hand pool a continuous, vigorous blooping boil {center of pool} with right hand pool doing some intermediate blooping from vent that seems to open from aperture at 8 O' clock or at SSW as you're looking at it. |

Both pools well below overflow with light gray water. Bubbling in left pool, gentle roiling in right pool. |

Water is still gray and was just below the "tuft of grass in the right vent." Boiling in the left vent, bubbles rising in the right vent. |

Both pools full very full. Left (north) pool an inch or two from its overhang. Right (south) pool 2 inches below its bathtub ring.
North vent sloshes occasionally with constant bubbling of varying strength. South vent intermittently bubbles after strong bubbling from north. |

Both cents are about 2/3 to 3/4 full of grey water, with both vents bubbling. The left vent has the more vigorous bubbles. |

Both vents still have water. North vent (left) heavily boiling and splashing up to 6 inches. South vent (right) lightly boiling at times with mostly light blooping bubbles. Similar to as described on 9-3-2022. No signs of major eruptions. |

Both vents still have water. Right vent is bubbling. Left vent has small splashes to 6 inches. there is what looks like some wetness inside the crater of both vents as if it has been splashed, but it may just be the natural colors. No evidence of anything big happening though. May also be just damp from the steam. |

Left pool is boiling and starting to fill the shallow part of the basin, just past the lip, but still a couple feet from overflow. Right pool is opaque blue and bubbling most of the time. |

Just following up on another gazer's previous observation. When we were here about 4 weeks ago, Twin was completely empty and Abyss and Black Pool were below OF and cool. Both look higher and warmer today, and the water in Twin is definitely steaming. Right/back vent has more water in it, clear and perhaps half full. Left/front vent more like a quarter to a third full and milky blue |

Water level has risen 2-3 inches since last week. Clumps of grass which have grown in the southern vent in past years have been killed. Clump of grass on east bank of the south vent is nearly submerged. |
