It appears there is some intermittent boiling on Deep Blue, but with the steam it may also be a mirage. |

Pool is as hot, full and wide as I have ever seen it and appears (thru binoculars) to be overflowing to the NW. The extent of the pool is far beyond the border vents on all sides. Drain seems to be completely empty. |

Even with poor weather, Deep Blue is full out to the berm and seems to be filling its OF channels! {From Fountain overlook with binoculars}. With the little bit of sunlight we had, it's a gorgeous deep blue even without the binoculars. Conversely, the pool to its left {Drain?} is almost empty. Can see some water in Kaleidoscope's pool. Usual vents are erupting but seem to have somewhat larger, more focused bursts. Also, 3 Vent is visible but low with what looks like orange cyanobacteria around the pool. |

1024 - Deep Blue in extensive overflow - never seen this before. Overflow was spread out all behind the geyser & in the front-left area. 1235 - water level has dropped a bit - still a full pool. 1320 - below overflow; almost full basin. 1433 - nearly full pool. I recall seeing one active, basin-marginal blipper today. |

It appears that the water level has risen dramatically in Deep Blue's pool so that the vents around it are now submerged. This change happened since 1335 on 8/6/19. |

Deep Blue Geyser's water level was relatively low in basin, but still visible. Never seen this before. Five active blippers in & around basin - all of which were subaerially exposed - never seen that before either. The ridge between Deep Blue's vent & K13's vent area was exposed to partially exposed - never seen that before. |
