39952 20 Jun 2025 @ 1600 20 Jun 2025 @ 1700 MAB Slow Fill and drop cycles - did make some progress in ~2hrs but not enough that I'd stay - saw one brief convection sighting in a lull in the wind
39951 20 Jun 2025 @ 1510 --- MAB arrived 1510 to dry platform and channels - east sinkhole way low - water level just filling inner circle almost to hog butt - may be too windy to see fill details
39644 03 Jun 2025 @ 1627 --- mhreed Pool up just above the bottom of the rounded rocks. Constant bubbling.
39590 31 May 2025 @ 1807 --- mhreed Runoff channels dry, water low in vent, steady bubbling.

39242 21 May 2025 @ 1643 --- MAB at 1st beach - if it was nice I'd stay and watch progress
39229 21 May 2025 @ 1358 --- MAB roughly same as this morn high level but didn't stay to see if that level was the new base level or if it would drop - needed an escape from wind
39213 21 May 2025 @ 0907 21 May 2025 @ 1007 MAB Slow Fill and drop cycles - water just at inner circle rising to 1st beach then receding
39177 19 May 2025 @ 1904 --- Ajw Quiet. Dry around runoff area. Water in crater low.
39071 15 May 2025 @ 1118 --- mhreed Empty, runoff channels dry

38933 10 May 2025 @ 0902 --- MAB dry channels - low east sinkhole - water levels appears about as described by CB 2 days ago will check this afternoon
38873 07 May 2025 @ 1705 --- cb pool is not in overflow. water level is fluctuating slightly. slight convection over the vent with a few tennis ball sized bubbles. Then pool drops. Runoff channels are dry. pool behind it is very low.
38815 03 May 2025 @ 2131 --- K.Cooper 3in below overflow
38789 03 May 2025 @ 1420 03 May 2025 @ 1630 MAB slight fill progress again at 10m cycles more easily seen now w some landmarks - after 1 hr one cycle held so that's the new base level - progress! 2nd hour same so a good rule of thumb unless nearing overflow might be to check it after an hour if it's low
38771 03 May 2025 @ 0909 03 May 2025 @ 1009 MAB In slow fill at inner circle - east sinkhole way low and all channels dry - fill cycles of subtle rise and fall were short like 10m - visible progress in 1 hour - will check again this afternoon

37094 20 Sep 2024 @ 0945 --- novakg Arrived to find Vixen's sinkhole full to back by the trees. Also, the Vixen sign has been moved further away from the boardwalk. Old notes with mention of water to the sign, etc., should be read with this change noted.
37029 17 Sep 2024 @ 1621 17 Sep 2024 @ 1625 htm pool higher than last night, occasional bubbles

35102 10 Jun 2024 @ 1316 10 Jun 2024 @ 1416 SantaFe108 1316: Water near the top of the tube. Big ole' wet spot on the front left side, but may be due to thunderstorms this morning. 1325: Water now touching the bottom of the rocks on the right. 1404: Since 1525 water has had a breathing pattern mentioned by previous entrants, not really moving overall, just fluctuating to at or just below the base of the right and back side rocks. Likely still rising, just sloooooooowly. 1416: Leaving, still on the rise, the "base level" of the breathing pattern seems to be higher.
35006 08 Jun 2024 @ 1202 --- cb bone dry. water is just above the vent tube h seems ti be fluctuating up & down incrementally. (
34967 07 Jun 2024 @ 1305 --- CrisG water about 4" below top of tube. water breathing but not bubbling. rear pool low and clear.

34707 26 May 2024 @ 0900 --- ypcaribou Time approximate cuz my phone died. Vixen's vent had water but it was still - not rising or falling. All runoff channels dry.
34609 18 May 2024 @ 1730 --- cb no change. pool behind Vixen is lower than yesterday
34576 16 May 2024 @ 1727 --- cb No change & no sign of an eruption since last post.
34544 13 May 2024 @ 1800 --- cb water level is just at the smooth section above the vent. Occational golf ball sized bubble breaks the surface. Runoff channels are bone dry. Pool in back of it is VERY low & clear. No activity from the features that were active last year up Tantalus Creek above the Vixen bridge
34374 28 Apr 2024 @ 1022 --- DanS Quiet. Water almost to top of funnel with no bubbles.
34327 24 Apr 2024 @ 1020 --- DanS Quiet. Water out of sight in funnel. Runoff channels drying.
34278 20 Apr 2024 @ 1114 --- mhreed Pool full, slightly blue (likely due to runoff from NBK-6), runoff channels very dry. Catch basin has little water.
34270 19 Apr 2024 @ 1645 19 Apr 2024 @ 1810 MAB Still in a slow fill with some progress - wet into the 2nd tier - at this level where it's easy to see rocks submerging then emerging may have seen something new: a drop then quick return which I believed signified progress ... until later when the 2nd drop was huger than the first - these only 2-3m apart not the more obvious ~20m cycle - left it after the 1810 drop with flow just reaching the grass clump near where the former sign was - if it was warmer I'd have stayed
34269 19 Apr 2024 @ 1244 19 Apr 2024 @ 1500 MAB East sinkhole lowest I've seen so obviously Vixen had not erupted in some time - slow fill in progress with rise and drop at approx ~20m cycles - flowed thru west notch for the first time @1343 and repeated - some drops bigger than others so no real progress seen
33913 24 Jan 2024 @ 1415 --- JR Full, milky blue but still mostly clear. Not even a bubble. Run off in features to the south of Vixen were active and had lots of milky run off.
28793 14 Oct 2023 @ 1614 --- MAB a tad fuller than @1255 but little real progress - occasional bubbles - more active fill seen 1705-1713 - pool dropped 1714 back to square one
28744 12 Oct 2023 @ 1615 --- JR Water at top of vent. No action during observed time.
28695 07 Oct 2023 @ 1621 --- MAB @ 1621 Surpassed the Known-Observed Record Duration of 2h32m. Previous Record was seen IE with all channels flowing and we left before the end so who knows the actual record duration. Didn't make the next Constant because I want to see the interval _after_ this one... if it will ever quit!
28696 07 Oct 2023 @ 1537 --- MAB FYI East sinkhole nearly refilled @ 1h 50m into the eruption
28694 07 Oct 2023 @ 1234 --- MAB 2nd visit fill is progressing now thru west notch - harder to see the drops at this stage
28693 07 Oct 2023 @ 0922 07 Oct 2023 @ 1015 MAB Arrived 0922 to a slow fill with rise and drop approx 20m cycles - left 1015 to Porcelain
28638 05 Oct 2023 @ 1233 --- cb no sign of recent activity. channels are dry. still water over the vent with water level just at the base of the hedgehog.
28563 30 Sep 2023 @ 0752 --- ypcaribou Gurgling in vent but no water seen. Wet all around and in channel. 2 sticks on deposit near vent on left side and 1 small wood piece right front. Vent appears to have been a target for stick tossing. 😠

28497 26 Sep 2023 @ 1904 --- novakg Vixen was still in eruption as I left Vixen viewing area near Veteran. Total known eruption now at 2 hours, 32 minutes.
28495 26 Sep 2023 @ 1632 26 Sep 2023 @ 1842 MAB RECORD SHATTERING DURATION - known observed previous record dur was 1h57m - I left this one at 2h10m - Gary was staying a tad longer. And this one was well IE when I 1st saw it. Details will be in the actual eruption entry when I get home.
28499 26 Sep 2023 @ 1052 26 Sep 2023 @ 1115 novakg In overflow. Hedgehog covered, water overflowing near boardwalk. By 1115, water had made it to the western notch.
28456 24 Sep 2023 @ 1546 24 Sep 2023 @ 1706 novakg 1546 Water slightly higher than when we left. 1649 to 1706 water rose generally and fell slightly. Occasional bubbles. Water not on a beach when we left.
