Wc, Oblong looks post-eruptive with percussive, voluminous steam. Prior eruption 1728 and I'm wondering if it had one of those follow-up eruptions it's been having 30-60 min after primary eruption |

Approximate time where I watched two pushes about 40 minutes apart.
Hard to call them pushes because the water level came up and was up for maybe 30s and never put anything out. |

Oblong may have had a decent push before I arrived this morning. I am seeing moving water even at far edges of the platform/terraces. Oblong’s crater still has water in it so it likely wasn’t an eruption. |

We *think* this was an eruption based on suddenly voluminous steam cloud and what looked like a few small water spikes but didn't want to say for sure without confirmation. For sure water spike 2002. Viewed on wc from our living room and couldn't see anyone else in that part of the basin to confirm. Heck of a push if not an eruption |

Just to be masochistic, I sat and watched for an hour, but it appears to be stuck in this mode where it's holding just at OF, so lightly overflowing most of the time, but the biscuits remain exposed. |

Just wondered if Oblong might be having one of those odd follow up eruptions. Wc is focused on Sawmill, but what little of Oblong is visible looks a lot more forceful than late post-eruptive steam. |

Enormous steam cloud that looked like an eruption from the wc. Can anyone verify or refute? It has had follow up eruptions in the past including one this year, so even with 2043 eruption, this time is a possibility. |

Oblong was down (islands visible ~3”) on approach 1137. It rose slowly, with water coming over both spillways by 1147. There was some bubbling center front of pool. Drool started at 1147 all across the usual spots.
1148 dropping & by 1149 I could see about 2” of islands. By 1151, 3” visible (& microburst wind). By 1154 down 3-4”.
1209 up & good overflow right spillway, then left one 1211. Drool began 1216, increasing across quickly. At 1219 it began dropping quickly.
By 1236, overflow on left & right spillways. 1240 looked down a little but picked up again 1243. Drool at 1244. It was all across 1245. Dropping 1246.
1257 overflow right & left spillways. Dropped back 1300, still dropping 1305. Headed back up 1312, with drool all across. Dropping by 1319.
Overall, runoff reaching to bottom of terraces near boardwalk with each drool. Standing water near boardwalk from left of sign & to the river. Some wind off and on, with only one large burst (microburst). |

Terraces partially black, but with an orange runoff channel flowing to the front right. Oblong’s pool has headed down right now, but overflow from last fill is reaching close to the boardwalk. |

It seems to be having good overflow and bubbling from two spots in the pool - calling these a push. Pushes seem to happen about every half hour - but I only had 3 data points, so more observations would be helpful. |

18 Sep 2019 @ 1755 |
Polly |
Cycles (overflow, drop, overflow) varied from about 10 to 29 minutes. Some of the cycles produced good overflow, but I only saw drool a couple of times. (Part of this might be due to wind & steamy conditions.) |

Oblong’s terraces have whitened up considerably from my last observation. (Some Oblong eruptions have been reported recently.) |

Terraces in front have black areas. I could see a little light flowing water up front from a previous overflow. I saw one fill during observation time that was very short-lived and didn’t produce much flow over the edge. |
| 13578 |
05 Sep 2019 @ 1340 |

Janet Jones |
Oblong looks like it’s lost many of the microbe mats. Addition: discussing it with Polly, the lightness I noticed is likely due to dry sinter. |

When we arrived, Oblong had lots of flowing water all the way down to the front. At first, it was having pushes (including a second push) about every 15-20 minutes. I saw "drool" at 1013, 1036, 1055, & 1122 (strong). After the push at 1122, the pool dropped and at least 6" of rock was visible on the left edge. This time the rise was a slow one, until I saw decent overflow at 1145. On the next rise, it had drool at 1150, then headed down at 1202. (This is similar behavior to what I saw last year. If so, if all continued well, it may have had an eruption within about an hour. We opted to leave, get some lunch, and go to Beehive, though. No eruption was seen this day.) |

Oblong’s pool was full on approach. At 1445, overflow was reaching the right front of the terraces. In general, Oblong was cycling with anywhere from 20 minute cycles to a couple of fairly deep drops and a couple of stalls. The drop at 1544 lasted about 20 minutes. The drop at 1617 came after a fairly strong overflow. (May have had “drool” but cloudy sky & hard to tell.) I could see maybe 8-9” of exposed rocks during this drop and I could barely see the water. It rose fairly quickly to about 2-3” of exposed islands, then stalled until ~1640. It had a push at 1648 and again at 1718. I hoped that the osprey catching a fish might be a good sign, but Oblong dropped after that push, then stalled a few inches down again. |

From the Inn parking lot, I looked up from what I had been doing to see a large amount of steam at Oblong. The steam stopped shortly after that. |

Oblong is steamy, with a steamy runoff into the river. Colors in the front runoff channel: orange, red orange, black, green. |

Oblong’s terraces have orange and white spots on the southeast side, but are gray on the northeast side. There are some small spots of water running down to the front with stronger overflow to the right side. Seems to be cycling, but too steamy to tell. |

Arrived at Oblong just after a fill and waited 25 minutes until the next one. Using the 'islands' as my gauge, pool level didn't drop as low as I've seen in years past. Water levels didn't move until about 3 minutes before the 'islands' were fully covered. The level was sustained for under 2 minutes and water was drooling over many edges. The next fill was 25 minutes later and was a tad better than the previous - lasting just over 2 minutes and flowing over the edges rather than drooling. The next fill was 28 minutes later. I left and didn't make it back in time to see the peak of the next fill and just missed it - about 25 minutes. And the last fill I watched was about 22 min. The fact that Oblong may be resuming a rhythm of cycling up and down and overflowing from most edges appears promising. |

Oblong down 1329, up 34, coming down 35, down with islands exposed 36, started up at 40, fully up at 42, started coming down, down at 45. Started coming up at 47 then was fully up at 50. Was fully down at 1354.
Cycles were 10 minutes long each. Pushes when at the top seemed to be very weak. Much weaker than previously observed over the last week. Boiling and overflow seemed normal. Though the pushes lasted a very short amount of time about a minute. Did not seem very enthusiastic about erupting |

Water started pouring over the rim, doming boil 6 inches to a foot and did not erupt. Water dropped 3 to 4 inches. 0926 water pouring out both spillways, big sizzling boil near big spillway 2 to 3 inches. Normal drop in water level after that. 0939 water spillway over the rim, level dropped just a bit and sizzling boil in 2 spots to 3 to 4 inches. Normal drop in water level after that.
0953 water spilled over the rim, dropped back just a bit and sizzling by small spillway for 2 minutes as water level dropped.
1005 water spilled over rim, sizzling boil in 3 spots, boiled bigger as level dropped.
1020 repeat of 0909 excep for a normal level drop. |
