18811 30 Jul 2021 @ 0905 30 Jul 2021 @ 1800 Micah Kipple It appeared to us that the eruptions generally got bigger throughout the day. Several of the last eruptions we saw sent water droplets to at least 10 feet and nearly hit the bumper logs but never crossed them.
18752 30 Jul 2021 @ 1000 --- Micah Kipple Please Note: durations are first splash to last splash out of the alcove.
18675 26 Jul 2021 @ 0939 26 Jul 2021 @ 1516 cb Pool is still a murky gray color.. The longer intervals from 0939 on represent the duration from start to when the Alcove vent stops spitting water and grumbling. The shorter ~2m intervals are when the north vent slows down and begins to drop but the Alcove continued. I wasn't including the Alcove ending spits in the 2m durations so I am noting the difference here.

9971 31 Aug 2018 @ 1019 --- MAB Water level is up, now covering the south-center rock. Water also visible in west vent area below the collapsed crater shelf.
9834 22 Aug 2018 @ 1839 --- cb water level is almost covering the center rocks and is high and boiling in the side feature.
9619 10 Aug 2018 @ 1328 --- MAB Low clear water, up a few inches since last sighting. Vigorous splashes from north vent.
9384 01 Aug 2018 @ 0943 --- MAB More water than my last visit - east side maybe 8-10" at its deepest; no water over the south-center rock; no water on west side. North vent splashing 1-2', grumbles and water noises from west vent but no water visible.
9303 26 Jul 2018 @ 1535 --- MAB LOW water. Water only present in the lower reaches of north and east side of the entire basin. West side is entirely dry. Clear water splashing 12-18" from the northerly vent.
19291 15 Jul 2018 @ 1825 --- research-mab 7-15-2018 CB CRATER SPRING 1825 See Note under Steamboat Vixen platform & runoff channel is wet, water pooled in its tube but I did not see an eruption in the 15 minutes I observed. Pearl still has a yellow hue. Porkchop water is back up to the rim of the pool. Green dragon runoff is again clear however the runoff channels are coated in brown. Yellow funnel has no visible water but I can hear deep grumbling with splashing down deep. Echinus water level is good with nice runoff and a weak 2 vent boil. (hum!) Crater Spring water is LOW and murky brown/gray. Emerald Spring is the same, clear, green with weak convection waves. https://geysertimes.org/note.php?id=9202
9129 11 Jul 2018 @ 0912 --- Tara Down about 3 feet from rim and boiling and bursting to about 1 foor in north end of crater.
19276 27 Jun 2018 @ 1800 --- research-mab 6-27-2018 CRATER SPRING – 1800 CB see Note under Steamboat Vixen is back to more regular play. The steam vent by Vixen is quieter. Pearl has bubbles breaking the surface. Pork chop is down about 4" from the rim. Green dragon is putting out chocolate brown runoff. Yellow funnel is way low, muddy brown and turbulent. Blue mud steam vents water/mud is not visable. Crater Spring water level is low as is Echinus. Echinus run off channel is dry in many areas. This back basin is much the same as last night except for Vixen. sorry for the long note! Forgot about Emerald. . . cuz it is the same! Boiling in the East thumb, green and fairly clear. https://geysertimes.org/note.php?id=8912
20473 07 Oct 2015 @ 1200 --- research-mab 10/7/2015 – Water/liquid back up for Mystic & Crater Yellow Funnel and Blue Mud still low. [generic day time]
20470 05 Oct 2015 @ 1200 --- research-mab 10/05/2015 Mystic, Green dragon, Crater & Yellow Funnel all MUCH lower liquid Blue Mud so low it sounds hollow as it bubbles deep. [generic day time]
4783 04 Aug 2000 @ 0850 04 Aug 2000 @ 1000 research-mab 08/04/2000 Crater Spring 0850-1000 3’-6’ eruptions
4788 02 Aug 1987 @ 1800 --- research-mab 8/2/1987 Crater Spring on the trail past Echinus – is erupting 2-3 feet high, not continually.
4841 02 Aug 1983 @ 1800 --- research-mab 8/2/1983 Marker at Crater Spring still in place so definitely dormant. Yellow Funnel still clear and overflowing. Blue drained.
4978 13 Oct 1979 @ 1800 --- research-mab 10/13/1979 Crater Spring was periodically throwing grey water across the trail this afternoon. Bursts were hitting out 6 to 8 feet. I moved the logs marking the trail back 5 feet. The water level in the pool itself was the lowest I have seen.
