33850 17 Jan 2024 @ 1547 --- K.Cooper quiet
28944 21 Oct 2023 @ 1404 --- OFVEC audible bubbles heard from boardwalk, splashed a few inches at 1406. Water at edge of pool
28574 30 Sep 2023 @ 1006 --- DanS Back to having some edge boils.
28481 26 Sep 2023 @ 1318 --- DanS Placid steaming blue pool with no boiling at all from observation point.
28110 08 Sep 2023 @ 0913 --- Kat Nice boiling
27847 29 Aug 2023 @ 1031 29 Aug 2023 @ 1038 Delta4Heavy85 (Wc) Having boils every minute or so, the best observed was at 16:33:31, reaching maybe 6" high and nice and wide.
26281 13 Jun 2023 @ 0922 --- Polly Looked like a strong boil - much more steam than usual (seen from the lower store area)
25318 04 May 2023 @ 1123 04 May 2023 @ 1125 JarnoO (wc) Large, sustained boiling at N rim. One of these episodes had a sustained boil easily double the height (±3ft perhaps?) of normal.
25310 01 May 2023 @ 1755 --- K.Cooper (wc) Period of decent boiling around this time, windy. Not tall, but wide and sustained. N Rim as well as Center and E side of the pool
25292 30 Apr 2023 @ 1416 --- SantaFe108 N rim boil, 6" tall.
25276 30 Apr 2023 @ 0930 --- RMichaels Based on amount of water collected around platform, it appears that Giantess recently had significant boiling events and runoff on the north side.
25272 29 Apr 2023 @ 2027 --- minissa From wc, pool still looks high plus you can track strong runoff to right {from wc perspective} and down hill from steam it is putting up. {I realize everything looks steamier when the day wanes, but still...}
25271 29 Apr 2023 @ 2006 --- K.Cooper (wc) High pool with lots of hot runoff visible from the cam. Strong boiling but mostly obscured by the steam.
25263 28 Apr 2023 @ 1410 28 Apr 2023 @ 1510 K.Cooper (wc) Another period of large N Rim boiling began at 1410. Every few minutes there is a large (1-2ft maybe?) boil sustained for about 5 sec. Still continuing as of 1456. Hard to tell wind speed.Calming down around 1510, although ongoing nice boils.
25261 28 Apr 2023 @ 1312 --- DanS Increased active boiling along entire North East rim with a few small splashes. Done by 1315. Followed up with a couple smaller boils.
25208 22 Apr 2023 @ 1143 --- DanS Edge boils along NW rim
24612 30 Oct 2022 @ 1210 --- SantaFe108 Large N-Rim boil, couldn't see through the steam cloud. Platform infront of N-Rim is wet and eastern runoff channel is wet too.
24334 10 Oct 2022 @ 1749 --- K.Cooper (wc) The most steam I have ever seen for 60F and low humidity. A couple of nice (2ft) N rim boils. Seems hot.
24196 03 Oct 2022 @ 1220 --- DanS Moderately strong boil
23988 21 Sep 2022 @ 1805 --- underarockphoto Observed from the webcam. No visible boiling (cam is zoomed out and there is too much steam to see when zoomed in) but pronounced steam rising from runoff channels both north and south. Dry conditions and relatively warm temps out - not really conducive for runoff steam.
23537 02 Sep 2022 @ 0946 --- Kat Low boils observed
25195 25 Aug 2022 @ 1728 --- Craigmon99 Much calmer than my previous visits the last 9 days. Wind could have a factor(?) NE rim boils very noisy but harder to see. North rim pitiful at best.
23387 24 Aug 2022 @ 1546 --- Kat Nice boil started at 1544
23353 22 Aug 2022 @ 1655 22 Aug 2022 @ 1704 K.Cooper (wc) Pool a tad higher than it has been recently, wind calm to moderate. No boils larger than a foot, but the boils we have observed have been pool wide and lasted more than 30sec a piece. All N-rim to center.
23335 21 Aug 2022 @ 1647 --- Craigmon99 5 foot boil for 10 seconds Largest boil I’ve ever seen personally
23303 20 Aug 2022 @ 1435 20 Aug 2022 @ 1454 Craigmon99 Still constantly boiling. One 3 foot burst at 1445
23270 19 Aug 2022 @ 1344 --- SantaFe108 Boiling to around ~6" on the north and northwestern rim every few minutes. Boiling never ceases entirely between each increase in energy.
23247 18 Aug 2022 @ 1252 --- Craigmon99 3 foot boil of note at 1252. Constant boiling from 1252 to 1330 when I left. Boiling continuous.
23238 17 Aug 2022 @ 1950 --- Craigmon99 3 foot center boil. Sustained for 20 seconds 4 foot boil North and north east rim 10 seconds at 2008
23195 15 Aug 2022 @ 1000 15 Aug 2022 @ 1030 aferrara Boiling constantly, variable intensity. 5 6" boils, one was sustained nearly a minute at the NE rim. 1 1' boil at 1021 that led to activity on full northern half of the pool. Most activity on NxNE rim, but shortlived and weak activity viewed across the pool.
23163 13 Aug 2022 @ 0615 13 Aug 2022 @ 1315 RMichaels Upon arrival, the runoff channel between Giantess and Teakettle Spring was wet down to the bottom of the hill (evidence of runoff overnight). Vault was at about mid-level, the same as it was 8/12/22. Most of the boiling events during the morning/afternoon were along the N and NW side of the pool (in contrast to the predominating N/NE and E boiling seen more frequently this season). Many wide boils seen throughout the morning. Most were about 6", but a handful were 1-2'. At 0919 a 2' N boil put heavy runoff out the N/NW side of the pool - enough to create a cascade of water down a jagged part of the sinter platform facing Teakettle spring. The best activity observed was in the half hour preceding Beehive's 1106 eruption. From 1027-1029 there was an extended period of N rim boiling that reached up to 2' and at times consumed large areas of the pool. At 1039 a wide NE boil that was 2-3 ft. put runoff out the N side of the pool. Generally impressive boils with moderate amounts of NW runoff continued until 1058, when I left after seeing Beehive's Indicator ie. Upon return at 1120, Vault had begun visibly dropping and the activity at Giantess had died down considerably. The one exception was at 1211, when a sudden NW boil 2' in height put a significant amount of runoff down the NW channel and again created a cascade along that side of the platform. No notable boiling events occurred from then until I departed at 1315.
23145 11 Aug 2022 @ 1550 11 Aug 2022 @ 1700 aferrara Constant boiling, mostly in north and northwest of pool. Averaging a ~6" boil every 1-5 minutes. Four boiling episodes over 1'. Poolwide boils fairly frequent, with a few energetic 6+" boils in center. Frequent gentle boil in Vault, only once sustained for more than 60s.
23120 09 Aug 2022 @ 1350 09 Aug 2022 @ 1520 RMichaels Vault's water level rose since yesterday and continued to rise slightly through this observation period. 1352 - 1 ft. NE boil with some runoff. 1402 wide N rim boil with multiple points of runoff. 1410 - estimated 2 ft. center pool/S rim boil. 1418 - impressive center pool/ S rim boil that I believe reached 3 ft. It did not maintain that height for long, but it broadened, lasted for 1m+, and was wide enough to cover the east half of the pool for probably 30s. 1422 and 1423 - low, wide N rim boils with runoff. 1425 and 1427 - wide N boils with notable runoff. Overall, activity quieted down after 1430 except for a NE boil at 1452 that put substantial runoff over the rim.
22930 29 Jul 2022 @ 0745 29 Jul 2022 @ 1100 RMichaels Consistent wide boiling along the north/northeast rim for most of the morning, typically at intervals of about 10 minutes. One boil at 0912 easily reached three feet tall, though it quickly died down and was isolated to the NE rim. The most active period was from 0930-1040, with at least three wide (though short in height) N/NE rim boils that put runoff over the edge of the pool between 0930 and 1000. At 1025 there was a NE rim boil up to about 15" that had some force behind it. At 1037 a NW rim boil put a moderate amount of runoff out that side of the pool. Except for the 1037 event, most boils seemed concentrated on the NE rim.
22927 29 Jul 2022 @ 1039 --- K.Cooper (wc) From around 1029 onward... Numerous wide, long-lasting, and some decently tall boils. Lots of white water visible from the camera, and only a minute (often less) between boils. Posting this note in hopes that someone in basin was watching it around this time, it would be nice to know how tall these boils actually are. Most boils appear to be along N-rim
22922 28 Jul 2022 @ 1419 --- K.Cooper (wc) The camera has spent a fair amount of time on Giantess today: Mostly small but very wide boils, a lot of them are only a minute or two apart. The biggest boil of the day was at 1418, similar to the largest ones in the past few days. A lot of the boils are along the East rim.
22887 27 Jul 2022 @ 2021 --- K.Cooper Center-south rim two-point boil (wc) Smaller in height than the ones yesterday, but wider. Again at 2022 but smaller and pretty much all South (and east?) Rim. It would be nice to have some in-basin confirmation of how large these boils actually are. The camera was only on Giantess from 2020 to 2023.
22848 26 Jul 2022 @ 1123 --- JarnoO (wc) Very heavy north rim boil. It seemed only a hair away of triggering an eruption. Regardless, Giantess is very active along the northern rim as of writing.
22549 13 Jul 2022 @ 2020 13 Jul 2022 @ 2050 RMichaels Giantess had 3 north rim boils that were 1-2 feet in height and sent water over the edge of the crater during this time. The runoff from the boils dampened half the width of the runoff channel near Teakettle Spring.
22405 08 Jul 2022 @ 1530 --- minissa Again, from Obs Pt with binoculars, in the past half hour when the wind died down, good convection was visible over the vent, and there was one more north face boil sustained for about 15 seconds with water pushed out forward and to the right. Just sayin'...
22403 08 Jul 2022 @ 1505 --- minissa From Observation Point with binoculars. Over the past half hour, there have been 3 short episodes of North face boiling with of put out the front, then to right and left. Pool had episodes of low but vigorous boiling, although the appearance of agitation was helped along by strong wind.
21689 03 Jun 2022 @ 1239 --- underarockphoto Continued big boils. Some are forceful enough to dome the water in blue-bubble like fashion. Mostly center pool.
21686 03 Jun 2022 @ 1147 --- K.Cooper Many large pool-wide boils this morning. Hard to estimate height from the wc, but I would guestimate a foot. Some boils are lasting 30 or so seconds.
21687 03 Jun 2022 @ 1056 03 Jun 2022 @ 1147 Betty nice center boiling on Giantess
21676 02 Jun 2022 @ 1906 --- K.Cooper Series of decent N-rim boils. Some of which were probably two feet. Center Pool had constant 2-3 inch "fizzling" for about 15min.
21317 16 May 2022 @ 1440 --- Brando Boiling on the entire rim closest to boardwalk
21163 04 May 2022 @ 1106 --- RMichaels ~1 foot north rim boil.
20775 01 Feb 2022 @ 1715 --- Brando Continuous rim boiling on the side closest to the cam
20681 13 Jan 2022 @ 0947 --- Graham Noisy boil. Another at 0955.
20665 11 Jan 2022 @ 1219 --- Graham Noisy boil.
19772 28 Sep 2021 @ 1854 --- K.Cooper (wc) Very impressive boils over the last little while. None of them were exceptionally tall (I estimate most of them were only 6'') but there were a lot of them. It also seemed like the center of the pool and the N-rim were constantly sizzling a few inches in height. The pool was higher during this time than I have seen it recently, it was pushing out an impressive amount of water down the main channel and was even flowing a good amount of water into the second channel. We also saw what we thought was runoff coming down the "backside" (closest to the bw). The wind picked up and seemed to kill it around 1900. Entering a note because this was the hottest I have seen 'tess in a long time.
19140 28 Aug 2021 @ 0945 28 Aug 2021 @ 2040 Ben VL Much increased activity from prev. days. High water level in Giantess' pool most of the day. Frequent boiling episodes, slowed down after the wind picked up but still put out semi frequent and relatively large activity despite the wind. Numerous 6"+ boils, several 1'+ boils, and a handful approaching 2'. Many with water pushing over the north or west rim. Near constant superheated boiling/bubbling across the pool. Boils are concentrated in the North/West quadrant, along the rim and towards the center of the pool, and are often doming, wide, or have multiple points. Vault steadily rising most of the day, peaked and started dropping later in the afternoon.
19125 27 Aug 2021 @ 1800 --- JarnoO (wc) Had some decent activity this morning, but overall it declined. Whether that was weather-induced I don't know, but the two days before had good boiling activity despite unfavorable winds. Perhaps Dome's playing a role in it, too, as its series started somewhere overnight.
19097 26 Aug 2021 @ 1800 --- JarnoO (wc) Good activity throughout the day. Multiple decent and sustained large boiling episodes seen, though the majority were bubble showers. Episodes happened during strong winds as well. North semicircle was focus of activity, nothing seen from southeast rim.
19069 26 Aug 2021 @ 1027 --- Brando (wc) Giantess is overflowing with center to pool wide boiling.
19073 26 Aug 2021 @ 1008 --- Ben VL N rim boil, over a foot in two places with a healthy amount of runoff over the N rim (compared to what I have seen). Definitely the strongest boil I've seen over the last couple days. No followup.
19058 25 Aug 2021 @ 1614 --- K.Cooper Lots of boils today
19040 24 Aug 2021 @ 1700 24 Aug 2021 @ 1901 K.Cooper Some good boils during this time. A few of them were over a foot tall, involved the entire north rim, and lasted about 10s. Overall just a lot of boiling during this time. Transitioned to alot center pool boils around 1822.
18975 21 Aug 2021 @ 1020 21 Aug 2021 @ 1100 Ben VL Vault up to more normal level after being low yesterday. Lot of bubbles in the back of the pool. GTS's pool higher than yesterday, at or just below the sharp edge. Near constant simmering noise with boilups. One 1'-1.5' boil at 1034 that put some runoff on the NE side of the pool near the channel. Wind started increasing around 1047 and the activity has slowed considerably.
18944 15 Aug 2021 @ 0935 --- Suzanne Overflowing with periodic very small boils (sizzling) at the edges of the pool.
18936 14 Aug 2021 @ 2016 --- Suzanne Water is clear and calm and overflowing slightly into the southeast channel.
18934 14 Aug 2021 @ 1733 --- K.Cooper Water beginning to become visible from the webcam.
18932 14 Aug 2021 @ 1415 --- RMichaels Water is visible in Giantess' crater.
18930 14 Aug 2021 @ 1346 --- Suzanne Calm. No visible water in the crater.
18914 13 Aug 2021 @ 1209 --- Suzanne Huffing and subterranean boiling heard at 1209, 1213, and 1214.. No visible water.
18913 13 Aug 2021 @ 1154 --- Brando As of 11:54, Giantess has barely any steam, no spiking or bursts, and the pool is completely empty.
18912 13 Aug 2021 @ 0025 --- Suzanne I saw spikes from the boardwalk at Beehive. A few bursts to maybe 50 feet, although height was difficult to determine in the dark. Activity lasted 3 to 4 minutes. I saw and heard nothing afterwards and left the hill at 0150.
18910 12 Aug 2021 @ 2042 12 Aug 2021 @ 2048 Brando 20:42: Near constant pool wide eruptions, and spiking up to 70 feet or higher. 20:44: Huge steam plume with spiking to almost 100 feet with water being flown all the way down to the bottom of Giantesses mound. 20:48: phase ended, pool empty and barely any steam.
18908 12 Aug 2021 @ 1755 --- Brando More big bursts going at 17:55, probably around 40-50 feet. Some spiking. Bursts are intermittent with an empty pool in between
18906 12 Aug 2021 @ 1355 --- rfick09 Large bursts starting up again at 13:55 as seen on webcam
18901 12 Aug 2021 @ 0602 --- Kat Water noted - spiking
18899 11 Aug 2021 @ 1740 --- Rocco Paperiello approx start of steam phase
18725 29 Jul 2021 @ 1217 --- SantaFe108 Heavy N rim boiling, more boiling at 1218, light boiling at 1222 and Vault bubbling.
18388 12 Jul 2021 @ 1050 12 Jul 2021 @ 1053 JarnoO (wc) Heavy north rim boils 1050, 1051 and late 1053. Undoubtedly also before and after, but I only typed in these times in my notepad. Turned to a flat pool after Beehive and the remainder of the day, for the brief times the cam was looking at the Hill rather than Sawmill & co.
18126 28 Jun 2021 @ 1334 --- TheHikingDude Brief 3 foot boil on north side
17998 22 Jun 2021 @ 0812 --- K.Cooper 2ft N-Rim boil
17742 13 Jun 2021 @ 0954 --- K.Cooper (wc) Decent N-Rim Boin on Giantess at this time, Sustained for 13 seconds. Again at 0955, 0956, and 0957.
17670 11 Jun 2021 @ 1034 11 Jun 2021 @ 1037 TheHikingDude Giantess was one inch below overflow at 10:34. 10:36: the whole north side was boiling to almost a foot.
17476 05 Jun 2021 @ 1210 05 Jun 2021 @ 1212 Polly Nice rim boil seen from Crested Pool. We could see water at times.
17373 02 Jun 2021 @ 1227 --- Graham 2 foot boil.
17366 02 Jun 2021 @ 0801 --- Graham Nice wide 2 feet plus boil.
17326 01 Jun 2021 @ 0845 --- Graham 1 to 2 foot boil on the rim. 0904, 0907 1 foot plus thick boil.
17292 30 May 2021 @ 2041 --- Ben VL Pool is low. Wind is calm. Somewhat steady simmering in the pool. I saw a few N rim boils in the 15 mins or so I was there. Max 1'ish. Slope behind teakettle wet down to 30' or so beyond the bottom of the slope.
17263 30 May 2021 @ 0922 --- Graham 2 foot boil close to Vault. 1 foot at 0925.
17112 17 May 2021 @ 1230 17 May 2021 @ 1235 RMichaels Pool has a constant sizzle. Saw one North rim boil to roughly 1 foot.
17100 15 May 2021 @ 1650 15 May 2021 @ 1815 Micah Kipple Saw and heard an explosive boil 3-6 feet high while at Aurum. Went over to the Giantess bench to investigate and have been observing since Aurum. North rim boils are frequent and wide, but not very high and not putting out a lot of overflow. Between concentrated boils the entire pool is in a simmering boil. Vault is only 2 inches below the rim and bubbling on the South en. Giabntess's Pool level is very high. The North Runoff channel is wet to the base of the Mound. Will continue observations until hunger takes hold or activity decreases.
16933 27 Apr 2021 @ 1322 --- DanS Intermittent moderate boiling alongEast rim
16906 21 Apr 2021 @ 1757 --- TheHikingDude Camera really zoomed into Giantess, could see some bubbling on the Southwest and North sides. No center boil.
16902 21 Apr 2021 @ 1158 21 Apr 2021 @ 1219 K.Cooper Multiple large boils, including N-rim, center pool, S-rim and full pool boils. Runoff has visibly increased over the last 24hrs (the area of orange bacteria has expanded)
16452 23 Oct 2020 @ 1824 23 Oct 2020 @ 1825 JarnoO (wc) Picture-perfect steam devil formed over Giantess, easily over 75-100 feet high (based on height measurements done in-basin during Giantess' eruption). Steam column started rotating @ 1824:34 and became very distinct from the rest of the steam 21 seconds later. Attained maximum height @ 1825:01, after which it rose upwards. Started dissipating @ 1825:12 and was gone @ 1825:22.
16363 07 Oct 2020 @ 2100 --- K.Cooper Some increase in activity, and a better overall status quo than the previous week, multiple larger boiling episodes this morning put out increased levels of water. As well, Giantess also had overall more boiling episodes, and longer periods of forced steam during the morning when the wind was calm. However, after the wind picked up in the afternoon both the boiling and forced steam episodes were minimal.
16359 07 Oct 2020 @ 0940 07 Oct 2020 @ 1230 Ben VL Pool level at the sharp rim at my arrival. The slope behind teakettle had a very small trickle on it. Had a handful of boiling episodes, the largest reached maybe 1.5' and put out a fair amount of water over the north rim. A couple others that put out a little water over the N. rim. Wind started picking up around 1200. Giantess calmed down and the pool dropped a little bit. Vault still right around the water level of right before the 9-10 GTS. Still has bubbles breaking the surface in the back. Infant seems a bit lower than yesterday.
16356 07 Oct 2020 @ 0752 --- K.Cooper Large boiling on Giantess at this time, due to steam the water could not be observed. However there was dramatically increased steam, and lots of forced steam at this time. The boil pushed out enough water to create a separate steam plume following the runoff down the channel. Runoff steam plume was not visible earlier in the morning. (Even when it was colder)
16333 05 Oct 2020 @ 1600 --- JarnoO (wc) No change in status quo over the last few days. SE runoff remains dark. Have not been able to observe many boiling episodes due to Mugwump and steamy starts of the day obscuring much of the pool and its steam (which is a good thing as Giantess' boiling - especially the larger ones - pretty much always had me on the edge of my seat). Bacterial mat has a very bright yellow color from cam. Last "general update note" for at least one or two weeks or until significant changes occur.
16320 02 Oct 2020 @ 1155 --- Ben VL Water level up to the top of the sharp rim at this time, dropped shortly after the wind really got started. Largest boil I saw in over an hour was probably 8"-10". Slope behind teakettle is just as wet as I saw 2.5 weeks ago. Vault is now at nearly the same level as it was an hour prior to the last Giantess, still has bubbles breaking the surface in the back.
16316 01 Oct 2020 @ 1720 --- JarnoO (wc) Maintained status quo (getting a bit repetitive here :D). Anyway, had some decent boiling activity throughout the day, peaking in the morning (again). This time the SE rim got involved as well, a marked break in boiling activity the past days where it was N rim-dominated. Heights usually didn't exceed 1-2 feet, perhaps 3. Two boiling episodes were of note: SE rim @ 0917:55 for ±25s at 2-3 feet and also SE rim 1054:08 for 20s 2-4 feet. Estimate would be that the SE rim had about 5% of all boiling activity, with the N rim accounting for the remainder. As for N rim regions, I estimate it was a nearly equal three-way split between the NW, N and NE regions as far as boiling episode region is considered, with the NE rim being ±more active in the afternoon than the other regions.
16314 01 Oct 2020 @ 1055 --- underarockphoto Substantial boil on Giantess. Duration roughly 9 seconds, started on the south rim and grew to a full pool boil. Height minimum of 4 feet, visual estimates range from 4 to 6+ft.
16312 30 Sep 2020 @ 1845 --- JarnoO (wc) Maintained status quo today. Overall nice boiling activity in the morning before the wind increased before noon, after which it was pretty much a flat pool for the remainder of the day. Boiling itself, however, was weaker compared with yesterday but average overall. At shorter intervals than yesterday, however (minutes apart rather than some 30-60 minutes yesterday that I could observe).
16311 30 Sep 2020 @ 0925 --- TheHikingDude (wc) Turned on the camera just in time to see a big amount of forced steam coming from the far right side of pool. This was followed by several big boils on NE side of pool and possibly a center boil.
16305 29 Sep 2020 @ 1353 --- Janet Jones 1-2 Ft boil near the rim that put out a nice amount of water
