Water level is still in sight with nice boils up to a foot high that don’t clear the rim top. Little Squirt ie and “Pygmy” is noisily sputtering and steaming. |

Water was visible with boiling, but water level was about 8" below the "back catch basin." Little Squirt was dry. |

Steam seemed to be significantly heavier than observed previously. It was intermittent between heavy and what I would consider regular. No vertical water was observed, but visibility was not ideal. This activity was observed for about 30 minutes on the webcam. |

Ever since around the time Little Squirt was first observed, I've been seeing intermittent bursts of steam lasting about <=1m occurring from Silver Spring at a frequency of about once every 2-5 minutes or so. Never saw any water, but I think it might be actual eruptive activity which never makes it out of the crater. |

While Little Squirt was still erupting, Silver Spring didn't drain and erupt. Instead, the water level had dropped to about 4-6" below the rim top and was occasionally splashing from the center of the pool. |

Empty and steaming. Little Squirt was off and Bronze was overflowing and sending up good bubbles (and had microbes growing in the vent). |
