GHG-15 (UTF on the path to Solitary on the right side as you head to Solitary) is much hotter and seems to be enlarging under the boardwalk. It seems rangers are monitoring the temperature. Looks REALLY hot. The UTF on the left side of the boardwalk has no microbes and occasionally sends up bubbles.When I went back for more documentation photos, at 1620, the side of GHG-15 (right) closest to Geyser Hill was softly roaring like a fumarole, but the left side of the large opening still had water in it and the vent closest to Solitary was splashing away. |

Around this time a large plume of steam rose ~northwest of me as viewed from the boardwalk near Clepsydra, a mile or more out, along or beyond Tangled Creek. A feature I could not identify had surges of water visible with he naked eye from the FPP boardwalk, apparently voluminous, but not extremely tall. It subsided <5m after I began observing, with visible steam continuing until I left the area. Unsure what this could have been. |

Small, intermittent spitter west of Cauliflower Geyser (= just right of a sightline between Cauliflower & Island Geyser, as seen from the Artemisia Trail / Old Road). Possibly the feature seen on satellite imagery: 44° 29' 01.01" North latitude; 110° 51' 03.92" West longitude. Does this have a name? If so, I'm unaware of it. |

Small mud geyser along south side of spur boardwalk at Thumb Paint Pots, West Thumb Geyser Basin. Janet Jones and I referred to it as "WT-Mud." Though larger eruptions had been reported by rangers, the eruptions we saw varied from bubbling to less than 1 foot to vigorous bursting up to 3 feet high. Intervals ranged from 2 to 5 minutes and durations were 10 to 15 seconds. We noted that if a large bubble failed to trigger an eruption, the actual eruption that followed would be more powerful. Here are the times I recorded: 1147, 1149:38, 1152:04, 1155:38, 1159:08, 1202:46 (break) 1232:50, 1236:03, 1239:56, 1241:06, 1243:08, 1247:38, 1252:42. |

Viewed from bench at Constant. From the vantage point on bench the geyser is just beyond and to the right (upslope) of small trees growing on slope. Eruption is quick, thin bursting - hard to photograph due to short duration and distance away. Bursts/jets are at least twice the height of the nearby young trees on the slope. For multiple burst sets all the bursts occurred within a few seconds. 1429 2 bursts. 1438 5 bursts. 1453 1 burst. 1456 1 burst. 1500 1 burst. 1507 2 bursts. 1509 6 bursts. 1514 3 bursts. Hard for this observer to tell if these are distinct eruptions or just larger activity in a long duration event. Steam from feature waxed and waned, but would need binoculars to see if activity was continuous. Based on note from Mkeller on Saturday July 18, 2020 this feature is about 30 feet NW of Collapsed Cave geyser. |

"Nemo" (next to Anemone) has a new steaming hole near it - apparently created by bison as there are two smaller holes closer to the boardwalk that are about that size. And there's another hole in that area (also steaming) that was different before (half filled in or smaller? Need to check photos). |

Several spikes show up on both loggers which line up almost perfectly from about 0800 till 1600. See attachments.
Theorising it could be a feature somewhere between the Lakes and Porkchop which, while erupting, causes both the Lakes and Porkchop to rise in temperature (and, at the end of such an eruption, drop in temperature simultaniously). Wouldn't be surprised if it were to be the Lakes themselves. |

It seems as if something near YVO's Gray Lakes Tributary Logger is erupting. Small spikes seem to be occurring about every 3 hours and cause a raise in the trace of less than a °C. Spike does look rather thin, so this would suggest an eruption of <= 2 minutes. Have looked through Norris' Back Basin map and table in The Geysers of Yellowstone, 5th edition, but couldn't really find a match in the southwestern portion of Back Basin. |

I suspect there are two features behind lone star that are behaving as geysers. The first one lies at the west edge of the hillside cluster just before the thick grass. I can only hear it periodically and during the loudest times I can see water splashing within its blackish orange Crater. The second feature is the farthest pool back within the grassy area. I have watched it for sometime and it certainly seems like the splashing is periodic. With long pauses between bursting episodes. |

"Bottlecap Geyser" ("new" geyser near Plume Geyser). Has been having occasional low splashing. Example: at 1556. I think "UNNG-GHG-14" has been used to refer to this feature.
