Splashy center boil, overflowing with a blue center. Black Pit's steam vent still going strong, the small spouter in the sand across from Black Pit is still not ie, just bubbling and overflowing. |

disimproving - much stronger action from main vent with waves going across the pool - some bloops to a foot in height -
Edit: BLACK PIT had a loud forceful steam vent on the N edge - subterranean water level drop I'd guess. At first I thought it was a collapse or blowout but the rim of that noisy vent is visible in earlier pics with hard-to-see-possible-water. |

wide strong center boil plus low boil from 2nd vent - darn - however these are fairly consistent without much real splashing or actual bloops so will see- the 2y-old sandy feature towards Vermilion area not splashing |

30 May 2021 @ 0925 BEN VL ECHINUS See Note under Steamboat
Emerald cloudy this morning (low wind) but cleared up quite a bit by the time I left. It seems like it has been alternating btwn clear and cloudy each day for a while. Echinus has also been alternating clear and murky each day. It seems that whenever ES is clear, Echinus has been that cloudy filthy brown color from last year, and visa versa. The one note where I saw something sort of interesting from a few days ago, ES was clear and Echinus was murky.

6 spikes. The last one reached ±39½°C before it dropped. Temperature fluctuations decreased in the ±12 hours prior and remained decreased until logger upload (±1300 MDT). Note that the loggers are in MST. |

Very, very low temperature fluctuations the past few days. During the regular, 12½-day cycle, large fluctuations (±10°C from average) would have been occurring by now, yet the fuctuations have only become smaller and smaller barring about 2 hours just after noon December 22. I don't think this is temperature-related - large fluctuations have happened regardless of temperature. Rather, it could be the temperature sensor got dislodged with the second eruption this year or a change in activity. The latter appears to be more likely as Echinus had small fluctuations recorded between September and October 2019; furthermore, the event after #2 this year did not result in a long "valley", while the second event did even though its maximum temperature was lower than that of the first event. See Echinus' notes on December 17 for those spikes. |

Another spike today (#2 post-eruptions). This one started @ 2322:46, when temperature rose 1.5°C to 34.0°C. Peak of 45.2°C was reached @ 2328:46, followed by a drop which reached its minimum @ 0206:46 at 10.5°C. Along with the remarkably long drop following the spike, recovery (time between drop minimum and first ≥30.0°C data point) to average temperature took longer than usual, taking until 0348:46 before the first ≥30.0°C temperature was recorded. The past months recovery from similar spikes (except for the first one in October) took only minutes, yet this one needed the better part of 2 hours to do so. Also noteworthy is that this is the first spike this "active phase" (≤October 2020 - onw.) to occur in a period _after_ spikes (in this case, eruptions) are expected to occur, where Echinus tends to have less-than-usual temperature fluctuations - i.e. the temperature hangs around its average of ±30°C for several days - before it widens up again for the next round of spikes. |

After two eruptions (2020-12-16 2149:08 E and 2020-12-17 0709:08 E), Echinus spiked again, this time only to up to 53.0°C. Spike started @ 1013:08 when temperature rose to 45.5°C, sustained above 50°C for three data points (6 minutes, 50.7°C, 53.0°C and 52.6°C, respectively), after which the temperature dropped quickly to below 30°C (1031:08 first datapoint) and then slowly to its minimum of 11.6°C @ 1213:08. Recovery appeared to be slow, with it still not having reached a stable average 26 minutes later, at which point the data ends. [Update] Temperature reached stability @ 1256:46. Another "mini spike" occurred @ 1300:46, when temperature rose to 31.4°C and reached its peak @ 1316:46 (34.2°C). Drop was, consequently, small, only to 28.5°C and had recovered two data points later (4 minutes). |

Spike started @ 1918:12, when temperature rose to 38.8°C from 32.5°C and reached its peak @ 1920:12 at 43.6°C. Temperature dropped to around 40°C and persisted for 2 data points (4 minutes), before rising sharply to 49.4°C @ 1926:12.

Two spikes recorded by the logger. First one starting @ 1818:10, peaking at 48.7°C @ 1824:10. Dropped in 6 data points (12 minutes) to 10.4°C. Second spike started @ 1838:10 and peaked at 54.5°C @ 1846:10. Dropped in 7 data points (14 minutes) to 19.8°C, though it rose 1.6°C at the 12 minute mark before it dropped again to the aforementioned temperature. Temperature fluctuations have been above average for several days, before narrowing in the afternoon. Same thing happened with previous spikes observed. |

At Echinus it doesn’t look like it erupted. The Cyanobacteria in the runoff channels looks intact and the grass on the edge of the pool is not knocked down. The water is mostly clear with only light opalescence. I wonder what it did? It is boiling strongly from the South vent, less so from the North vent. |

[EDIT: Forgot to compensate for DST] Three "slow spikes" on the logger in this timespan. The first started @ 0418:08 and only peaked @ 0426:08 (45.1°C) after staying at above average temperatures (±34.8°C in the hour preceding) those 8 minutes. Dropped in 3 data points to 26.4°C @ 0430:08. Second spike started @ 0432:08 (28.7°C) and reached peak @ 0444:08 (48.7°C). Drop in 4 data points to 17.6°C @ 0452:08. Third and final spike started @ 0454:08, with temperature rising immediately to 35.7°C and reaching peak @ 0458:08 (49.6°C). Drop in 4 data points to 18.4°C @ 0506:08. Temperature fluctuations before these set of spikes were abnormally high the previous 3¼ days (8½ days if the intermezzo of about 24 hours on the 25th is also counted), with less than usual fluctuations in the ±18 hours immediately before the spikes. |

NOTE: YVO logger output is by default in MST. I have adjusted the time to MDT (+1 hour). Two spikes to >45°C. First one @ 2121:54 to 47.7°C (with first rise two minutes earlier to 41.2°C, from 33.3°C) and dropped thereafter to 17.9°C @ 2129:54. Second spike @ 2139:54 to 45.3°C for two datapoints (2139:54 & 2141:54), which rose from 29.8°C @ 2135:54 and 37.5°C 2 minutes later. Spikes were preceded and followed by generally less-than-average temperature fluctuations starting from ±1000 up until ±30 minutes before these spikes. |

Developing terraced deposits at runoff edge (similar to Cistern but on a much smaller scale). Runoff at about half of what it was on 06/06/20. |

looks much the same as last year. Small boil in the center of the pool and one on the east side. Nice red color on the edges melding into more blue/green toward the center. Nice overflow with little debris in the overflow channels. |

same overflow that I've seen. Pool at pretty much the same level. But, the 2 boiling points have a diminished boil. Not nearly as intense a boil as I've seen, smaller in diameter and height. |
