Fantastic late bursts on GF: tall, strong 5th, 6th, 7th. Decent 8th, small 9th, 10th barely ejected water beyond crater. Sometimes pays to stay… |

I believe GF is post-eruptive. At 1030 water level was about a foot below the rim. there was light boiling around the inside of the rim. The boiling stopped at 1100 and water dropped a few inches. |

Smell of eggs |
Sat around G.F. From 12:20 to 15:50 the pool looked to be in recovery from the previous eruption, the pool had risen anywhere 6”-1’4’ from the time I sat, I assume that morning eruption was anywhere from 8:30 - 10:00. |

Pool pretty darn low. Guessing it had a long series last night. It is possible it could have been a crash. But if it is, it's a very large crash. |
