34124 17 Mar 2024 @ 1035 17 Mar 2024 @ 1320 Mkeller No activity. No minors. The berm around the vent looks weathered like it hasn’t had a major in a while. Pool level never changed and I never saw any convection either
31724 29 Nov 2023 @ 1616 --- JR Various points throughout the day Whirligig seemed low, but couldn't confirm anything visual or audible.
29311 31 Oct 2023 @ 1700 --- MAB filled a bit in the last hours! Not quite reaching ovfl but ... progress!
29302 31 Oct 2023 @ 0846 31 Oct 2023 @ 1255 MAB Cloudy blue & LOW - NOT EVEN CLOSE to overflow - down a vertical foot! No change or fill in 4+ hrs - only a trickle coming in from channels upstream
29050 22 Oct 2023 @ 1310 22 Oct 2023 @ 1900 SantaFe108 In good overflow on arrival. Lots of suds on cloudy green pool surface with rooster tail + shore vent blips and bubbling near the front runoff channel. Did not change at all between 1310 and 1900.
28985 21 Oct 2023 @ 1600 --- JR Gentle overflow. Blue, slightly murky.
28916 20 Oct 2023 @ 0803 20 Oct 2023 @ 1040 MAB Quiet - left channel with good flow - right channel is wet but not steadily overflowing - upon arrival it looked like it just regained ovfl after a minor but stayed the same for 2.5 hours - as Constant heated up prior to erupting poor Whirligig looked cold in comparison
28886 19 Oct 2023 @ 1303 19 Oct 2023 @ 1518 DanS No change in runoff, pool height or indication of wanting to erupt.
28797 14 Oct 2023 @ 0835 --- MAB in overflow 0835 - left @1136 - same observed 1400-1455 - did see a slight sign of life starting 1044 teeny rooster tail blips and faint brief main vent convection - rooster tail looked a little better @ 1740
28747 12 Oct 2023 @ 1700 --- JR Overflowing. Clear.
28646 05 Oct 2023 @ 1310 05 Oct 2023 @ 1430 cb pool is overflowing out both channels. no activity. no convection or bubbling from the roostertail even. LOTS of white foamy stuff floating on the surface.

28297 17 Sep 2023 @ 0900 17 Sep 2023 @ 1158 SantaFe108 No eruptions during this time, overflow slowly getting better over the course of 3 hours. Not even a bubble or a blip from Rooster Tail, just flat pool the whole time.
28253 14 Sep 2023 @ 1110 14 Sep 2023 @ 1215 CP Went into overflow about 11:15 and was still overflowing when we left at 12:15.
28155 09 Sep 2023 @ 1322 --- steve Perhaps a very weak minor. There was stronger overflow, some churning, and the rooster tail vent bubbled. Nothing went airborne
27518 11 Aug 2023 @ 1047 --- cb most have had a good eruption in the last hour. pool is ~2' below overflow
27223 25 Jul 2023 @ 0939 --- mhreed Pool in overflow. Minimal convection over rooster tail vent. Back to a more normal turquoise color.

26666 25 Jun 2023 @ 1128 --- steve A really weak excuse for a minor. Main vent rolled a bit and the rooster tail and shore vents were on for just a few seconds
26650 24 Jun 2023 @ 1732 --- mhreed Pool rising, not yet at overflow. At 1752, rock on left side of pool covered.

23719 10 Sep 2022 @ 1327 --- CP Small push
23635 07 Sep 2022 @ 2007 --- MAB refilling - overflow 2027 - possible brief minor 2133 - stupid cloud again - left @ 80min post seen overflow 2148
23614 06 Sep 2022 @ 1935 --- MAB Low - refilling

22151 27 Jun 2022 @ 1244 --- cb overflow at 1232 in both channels. 1322 shore and Rooster tail small blips that are off and on until Whirligig started
21673 02 Jun 2022 @ 1520 02 Jun 2022 @ 1525 CP Should have had something In this range but was a no show.
20101 24 Oct 2021 @ 1751 --- MAB not in overflow
20115 24 Oct 2021 @ 0853 --- MAB low pool refilling post eruption
19926 06 Oct 2021 @ 1703 --- cb came back from back basin and missed Whirligig next eruption by 15- 20m. pool is low in the crater but starting to fill. double drat.

19695 23 Sep 2021 @ 1015 23 Sep 2021 @ 1018 SteveO 1015 start of overflow after 0923 minor. 1018 side vents started bubbling for about 10 seconds with increased overflow, pool did not below overflow but overflow dropped back to just a trickle.
19234 01 Sep 2021 @ 1135 01 Sep 2021 @ 1159 MAB did a VERY educational series of FLIR shots during overflow
19134 28 Aug 2021 @ 1651 --- Graham First overflow since the major.
19079 25 Aug 2021 @ 1233 --- kc Pool below overflow when vents started.
19076 25 Aug 2021 @ 1149 --- kc Slight pause about 5 minutes in. Good height.
18802 02 Aug 2021 @ 1503 --- cb pool VERY low, just above the inner vent. lots of red rim exposed. just recently erupted. ~10-20m ago.
18663 25 Jul 2021 @ 1814 --- cb As I approached Porcelain basin I saw that Whirligig's pool was VERY LOW. ~5'. I just missed a full eruption. Walked down and the pool was filling but still had 4' of exposed red. Walked away figuring I had a long wait and was surprised when I got above Hurricane Vent to see Graceful and heard it ie @ 1839. Pool was NOT in overflow when it erupted! End 1841.
18487 17 Jul 2021 @ 1917 --- cb I just missed a full eruption by minutes. Pool was drained exposing 5' of red rim.
18391 12 Jul 2021 @ 1207 12 Jul 2021 @ 1212 cb pool not in overflow but the side vent is playing 1" - 2". nothing from other vents.
18237 01 Jul 2021 @ 1008 01 Jul 2021 @ 1024 JarnoO Logger probe replaced. Previously averaged around 20°C with Whirligig spikes reaching up to 45°C or higher, current trace averages around 50°C with Whirligig spikes reaching up to 70°C or higher.
19271 24 Jun 2021 @ 0541 24 Jun 2021 @ 0633 MAB NOTE to future researchers - Missing from the data here is a Whirligig minor at 0541 and a full eruption at 0633. Based on the YVO temperature trace, the interval information here is incomplete. These eruptions were disputed and deleted, but I believe they should be included, or at least a future researcher can make the choice to include them, or not, in their study of Whirligig, so I note them here.
17752 13 Jun 2021 @ 1630 --- cb A phenomenal amount of HOT water coming down the channel from pinwheel that has turned pinwheels channel whiteish. Channel SMELLS BAD, like decayed organic matter!
17751 13 Jun 2021 @ 1302 --- novakg Whirligig's pool recovered. 27 minute recovery.
17345 01 Jun 2021 @ 1435 --- Bhoffer Attempted eruption. Pool fully recovered at 1501.
17283 30 May 2021 @ 1449 --- cb ~1' below over flow
17207 27 May 2021 @ 0902 --- MAB refilling - ~2ft red shore exposed
17019 09 May 2021 @ 1315 09 May 2021 @ 1400 cb pool was high and in overflow during this time period. side and shore vent played briefly 3 times while we waited. once right before the Constant eruption and just before Constants pool crashes.
16988 05 May 2021 @ 0655 --- JarnoO From this time the number of non-minors increased while there were hardly any minors. Also no minors between the last two non-minors. In previous years, an increase in non-minors while simultaneously the number of minors decreased, announced the arrival of a disturbance.
16869 05 Apr 2021 @ 1051 05 Apr 2021 @ 1133 JarnoO No data
16857 01 Mar 2021 @ 1146 02 Mar 2021 @ 1309 JarnoO No data between these times.
16828 24 Jan 2021 @ 1602 --- markwolf looks low from overlook. post eruption? lots of silty runoff from graceful area hitting logger
16814 19 Jan 2021 @ 1200 --- JarnoO Appears to have almost completed the switch to solely non-minor eruptions in the previous 24h.
16812 17 Jan 2021 @ 1500 18 Jan 2021 @ 1200 JarnoO Minors started to become more spaced out around 1500 January 17 and occurred roughly hourly by 1800. This culminated into the first non-minor since ±April/May 2020 at 0220 January 18. It has since had two non-minors before logger data was uploaded @ 1200. Previous disturbances featured Whirligig switching from exclusively minors to exclusively non-minors for roughly the duration of the disturbance. Therefore, my assumption is that there's a disturbance currently ongoing at Norris.
13708 15 Sep 2019 @ 1219 --- Skookum False start w/ pulsating over main vent with two splashes, splashing from rooster tail, and heavy overflow before subsiding to a light overflow.
13707 15 Sep 2019 @ 1156 --- Skookum False start w/ pulsating over main vent, splashing from rooster tail, and heavy overflow before subsiding to a light overflow.
13706 15 Sep 2019 @ 1130 --- Skookum False start w/ pulsating over main vent, splashing from rooster tail, and heavy overflow before subsiding to a light overflow.
13563 04 Sep 2019 @ 0945 --- novakg The next eruption was a major. A woman I met at Whirligig stayed after I left and later showed me the video on her phone. Definitely a major and she estimated the duration to be around 4 minutes.
13243 14 Aug 2019 @ 1412 --- cb very brief weak attempt to start. pool stayed in overflow
13242 14 Aug 2019 @ 1207 --- cb weak attempt to erupt
11588 04 Jun 2019 @ 1419 --- novakg NQAM. Can't save this as an eruption. Don't know why.
11587 04 Jun 2019 @ 1335 --- novakg NQAM. Can't submit this as an eruption. IDK.
11247 15 May 2019 @ 1323 --- cb once again Whirligig started to boil, all the vents started, the helicopter sound started: played for a few seconds and then Constant started and Whirligig stopped. pool stayed at overflow level.
11246 15 May 2019 @ 1247 --- cb played for 25s. 1 small (< 1') burst from main vent. rooster tail tried to start. pool did not drain. still in overflow. started to make the helicopter sounds but quit quickly. * Constant erupted just before this and still had a boil when Whirligig started.
11228 13 May 2019 @ 1811 13 May 2019 @ 1813 steve Whirligig tried to start twice with both rooster tails active for 30 second and heavy convection over the main vent. About 2 minutes apart.
11227 13 May 2019 @ 1741 --- steve Whirligig tried to start. The pool had a big convection and the rooster tail vent erupted for15-20 seconds, then went quiet and the pool dropped about a centimeter or less. No eruption from the main vent.
10969 01 Apr 2019 @ 0500 --- JarnoO It looks as if Whirligig has switched, without much of a transition, to an eruptive pattern consisting out of largely 'major'/'normal' eruptions since 0000 on 30 March 2019.
10774 20 Dec 2018 @ 1400 --- JarnoO Whirligig seems to have entered a phase with what seems to be very frequent minor eruptions (up to 6+ per 3 hours) and few majors (one or two or even none per day). This seems to have developed gradually since December 2.

10029 04 Sep 2018 @ 1557 --- novakg Appeared to be in recovery after an eruption. I didn't go down the hill for a closer look.
9430 03 Aug 2018 @ 0820 --- WillBoekel light overflow
8846 22 Jun 2018 @ 1205 --- User34 First overflow about this time
8679 14 Jun 2018 @ 1614 --- cb false start or a minor. not sure what to call it. Nice explosive start with all vents playing and then it suddenly stopped. pool drained a few inches but recovered to overflow in 25m. I had to leave at 1645 and no eruption by that point
8182 13 May 2018 @ 1348 --- sfavor erupted sometime in the last hour
7725 20 Oct 2017 @ 1757 --- MAB Post eruptive 1757 - I don't usually put these in but thought I would since YVO isn't updating.
