Electronic time is from Bluetooth logger located in grand runoff channel. The electronic time has nothing to do with telemetered loggers. I thought Bluetooth was toast as the the last time I tried to connect to the logger, it failed. |

Walked up to Geyser approximately 1410, noted period of sustained heavy overflow starting at 1415 and ending shortly before turban at 1423. no knowledge of when prior Turban was, but this behaved like a delay interval. |

Grand's pool is still far below overflow. I am uncertain if there is even water visible. If there is it is just barely above the Vent level and quiet. No boiling or turbulence observed.
Update 0749: water just barely visible from near Rift. |

It was a Grand start, abruptly, and the initial burst was so high that, if I had seen it out of context, I would swear it was a second burst. And it was the first I have ever seen that the second burst height did not exceed the initial. |
