14975 13 Jul 2020 @ 2038 13 Jul 2020 @ 2210 Ben VL We had left around 1945 as a rainstorm came in. We got a pretty sunset with deep red and gray all around us. Arrived about 2038 with NV bursting dirty water. Wind shifted to the platforms and back away again. We got restarts at 2122, 2128, & 2139. Wind shifted back to the platforms at 2140. Wind shifted back to the restart area just after we walked away. One more restart seen from the dip at 2159. We left shortly after that.
14974 13 Jul 2020 @ 0930 13 Jul 2020 @ 1600 cb SB had some nice concerted minors this morning that had NVV with a SV babbling brook. One at 1219 that had 3 consecutive, back to back, CNVV minors with a SV babbling brook. Nothing much after that and very little consistent water flowing down the SV runoff channel the rest of the afternoon. ** 1700 I went back down to check on SB and still not much water consistently running down SVRO channel, weak minors with hardly any runoff. SB proves me wrong!
14970 13 Jul 2020 @ 0735 13 Jul 2020 @ 0800 bbev 3D, 21hrs PE; Improved from last night, more concerted play with some vert from NV. Better SV runoff. Difficult to see if there is any water coming down back shoulder.

Upper deck getting rained on. Middle deck mostly dry except when the wind shifts. Cistern Spring a few inches below overflow.
14763 28 Jun 2020 @ 2145 --- William No Steamboat when I left at 21:45. Some high volume minors at 20:43 but could not get organized.
14761 28 Jun 2020 @ 1930 --- Graham Strong minor at 0908 that could have made it start. Good volume all day. Another push at ~1900 but no SB as of 1930.
14756 28 Jun 2020 @ 0815 28 Jun 2020 @ 1000 Ben VL Report of a radio call for minors at around 0600. Frequent NV vertical during my sit, and a lot better volume and rumbly noises than yesterday. At 0908 we had a huge minor with sustained, thick, and tall NV vertical with SC fountaining and a 4.75 on the flea scale. Could have started if it wanted. No significant follow up.
14748 27 Jun 2020 @ 1930 27 Jun 2020 @ 2230 William Notable concerted vertical minors at 20:25 and 22:01. That said, no follow up or sustain in action. Runoff observed at steerage today was not particularly voluminous or consistent.
14927 27 Jun 2020 @ 0800 27 Jun 2020 @ 1825 Ben VL Activity picked up after 1000. We had frequent nice minors throughout the afternoon with NV vertical and decent volume, but did not have fantastic runoff and usually did not get significant follow up.
14743 27 Jun 2020 @ 0726 27 Jun 2020 @ 0751 bbev 3D, 20 hrs PE; Both vents active. SV with light to mod runoff. Water trickling down back shoulder and far south runoff. Did not see any vert. in short observation.
14737 26 Jun 2020 @ 1710 --- cb 3D 6H PE. mostly weak minors, some concerted. Wispy NV ~15', SV ~5' - 8', some sustained enough to move some debris a few feet more down the channel. SV runoff channel wet with lots of debris from the last eruption still scattered all over the channel. CS is overflowing on all sides with a vigorous boil.
14736 26 Jun 2020 @ 1000 26 Jun 2020 @ 1500 Micah Kipple A noticeable, but not jaw-dropping improvement from Bill's observations. Mostly wispy angled activity from North and South with some weak concerted minors, perhaps one or two splashes of vertical from North. Near the end of our observation period there was a heavier concerted minor that moved gravel down the channel towards the bridge and sent water all the way to the bridge finally.
14734 26 Jun 2020 @ 0918 26 Jun 2020 @ 0954 bbev 2D, 21.5hrs PE; Steamy, soft, deep grumble, SV channel and shoulder dry.0923 first spritz from both vents. 0927 very light spritz from NV. CS high and overflowing. Steam coming from normal NV channel area at steerage. Overall, very quiet during brief observation.
14729 25 Jun 2020 @ 1842 25 Jun 2020 @ 1920 cb 2D7H PE. Steamboat is still gently steaming and grumbling. 1 NV 10' angled splash at 1849 and another at 1902. No water from SV, just steaming. Channels dry except some rain puddling in low depressions in the channels. Cistern Spring is in overflow with a vigorous boil. It is still very steamy and hard to see into the pool.
14728 25 Jun 2020 @ 1036 --- underarockphoto That is NOT Steamboat, please read this before entering anything...
14726 25 Jun 2020 @ 0825 --- cb 1D 20.5 H PE. SB is gently huffing/lightly grumbling mostly steam with an 1 observed wispy 5' - 8' angled jet from NV. SV just steam. Runoff channels are dry. No pooling of water in either channel as observed from middle deck. Cistern Spring is in overflow. It is to steamy to see what the boil looks like.
14725 24 Jun 2020 @ 1830 --- cb 🎣Sorry, Gone fishin!🎣
14717 23 Jun 2020 @ 2020 23 Jun 2020 @ 2055 Ben VL 8H 38M in. In secondary water phase. NV rather thick angled and vertical jetting 20'-35', SV 15'-25'. Beautiful in the evening light. Cistern is about 2' below overflow.
14755 22 Jun 2020 @ 0616 22 Jun 2020 @ 2200 Ben VL NV more active than yesterday upon arrival, but not as much progression as I would have thought. Spent most of the day at decker. Fairly decent activity with a lot of nice minors throughout the day. I noted WooHoo or better minors at 1105, 19, 1315, & 1816 (I probably missed some as well). However, there was a decent minor multiple times per hour. Often without much follow up. At 2110 we had a very sustained push event with stronger minors noted at 2110, 12, 17, 24, 25, 34, 38, 40 and probably a couple others I missed. It maintained high energy and water output but never gave an attempt at at erupting.
14708 21 Jun 2020 @ 1630 21 Jun 2020 @ 1940 Ben VL Nice improvement from this morning. Bounce at 1638, 42, & 43. Woo's noted at 1731, 1844, 1910, & 1940. Play is mostly SV dominant with frequent sustained angled minors putting out runoff pushes. Nothing greater than a babbling brook. NV less active and usually wispy, but it had some decent angled volume accompanying almost all vertical it put out. Long pauses between most events. SV channel is already starting to turn white.
14704 21 Jun 2020 @ 0850 21 Jun 2020 @ 0920 JeffL ~2D16H Water is back in the system. Deep grumbling. Mostly SV play with a couple decentish splashes out of both vents. Water barely trickling down sv runoff. Cistern in overflow, too steamy to see boil.
14701 21 Jun 2020 @ 0743 21 Jun 2020 @ 0800 bbev 2D,14hrs PE: SV runoff damp, no running water as l arrived. NV runoff no longer trickling water as it had been yesterday morning. Deep grumbling and steamy from SB. 0751 first water seen from either vents, NV 10-15', SV 5'. 0756 spritzy NV, splash from SV. CS high and overflowing, light boil in opalescent pool.
14700 20 Jun 2020 @ 2100 --- Ben VL No change since this AM
14687 20 Jun 2020 @ 0757 --- bbev 1D, 14.5 hrs post erution: quiet and steamy. CS is just 1-2" below overflow. Clear pool, very steamy and difficult to see any boil, no waves or sound. Trough is mostly clear of debris up to bridge. Very light trickle at bottom of SV, with no water seen in SV runoff from mid deck.
14681 19 Jun 2020 @ 1728 --- cb 1D PE. SB platform is quiet. Vents are gently steaming and channels are mostly dry. Still a trickle of water in the NV and SV run off channels at steerage. Cistern Spring has completely drained. No water or steam visible.
14676 19 Jun 2020 @ 1034 --- cb 17H PE. platform quiet. SV channel mostly dry at middle deck but has a trickle of water in the runoff channel at the footbridge. NV channel has a trickle of water running down the channel from some small bubblers within the channel. vents gently steaming. Cistern Spring is ~ 2' below the rim of the inner tube and has a 3" wet bathtub ring above the water level. It has a few random ping pong ball/tennis ball sized bubbles that are breaking the surface of the pool in the center and on the side closest to the bw.
14659 17 Jun 2020 @ 2230 --- hurleyintjl No eruption as of 22:30
14658 17 Jun 2020 @ 0845 17 Jun 2020 @ 2100 cb Increased activity from yesterday. Lots of concerted minors where SV takes over with large fountaining and heavy runoff but not much tall NV vertical seen in the minor play. A few "bounces" where hopeful viewers seem to think/hope NV will move over but, nope! Cistern is still high with a good boil.
14653 16 Jun 2020 @ 2130 --- hurleyintjl No eruption as of 2130
14651 16 Jun 2020 @ 1850 16 Jun 2020 @ 1930 cb 3D 20H post eruptive. Water levels in both vents have improved. Both vents are putting out more water by volume. SV Babbling brook at 1902 + fair SV fountain at 1904 with nice BB. NV angled jetting ~25' and SV ~10'+. Good mix of concerted minors. No vertical. Loud percussive grumbling and pops. 1914 CNVSVH NV almost had some vertical action. Cistern Spring has an increase in its boil. It has VIGOROUS boil with big blooping/roiling boils.
14649 16 Jun 2020 @ 1145 16 Jun 2020 @ 1245 cb 3D 13H post eruptive. I spent a hour at SB in between rain storms. Minors are mostly angled. A few are concerted. All lack height, energy and water. One "meh" concerted minor @ 1217 had a weak babbling brook but, it failed to move any of the debris that had gathered in low depressions, further down the channel. The trough has no accumulation of debris from the previous eruption yet. Typically strong SV minors will move small rocks and sinter bits from the previous eruption down the channel and they lodge at the base of the runoff channel in the trough. Stronger minors will move these bit closer to the channel directly infront of the foot bridge at Steerage. (where the big rock used to be) At this point I dont see any evidence of significant SV minors based on all the debris still on the channel and nothing in the trough has changed since Sunday evening. Cistern Spring is the same as yesterday.
14646 15 Jun 2020 @ 1832 --- cb 2D 20H post eruptive. more water in the system, SV run off channel is wet to the bridge but not a steady trickle of water yet. SV minors are pushing some debris from the last eruption about 10 yards down the channel where it is accumulating. Some concerted minors but they are followed by ~5m of no activity. Activity tonight seemed to be more SV dominated WHEN it was active. Cistern Spring is the same as this morning; high and in overflow.
14644 15 Jun 2020 @ 0915 --- cb 2D 10.5H post eruptive. Water has just barely come back to the platform. 8' angled jet from NV as viewed from the upper platform. (not visable from the middle platform) SV 5' angled jet. Both runoff channels are dry. Just the splash zones next to the vents are damp. Cistern Spring is overflowing with a nice boil (better than last night) and the pool is high.
14641 14 Jun 2020 @ 1900 --- cb 1D 20.5H post eruptive. SB platform is dry as a bone! ET, Jabba, the Dip are all dry. Both vents are just steaming; no huffing sounds at all. Cistern Spring is in overflow, the pool is high (water level is just covering the scalloped edges.) It is a milky, opalescent blue and has a very weak boil. At the trough, debris from the last eruption has been pushed into the channel directly in front of the foot bridge and the standing water is clear.
14635 14 Jun 2020 @ 0900 14 Jun 2020 @ 0930 cb 1D 10H post eruptive. SB platform is dry as are both run off channels. The storm is coming in and i wanted to see the platform before the rain came in. Both vents are gently steaming with an occasional huff of steam. Cistern Spring water level is ~2.5' below overflow. Water is a opalescent blue, it is steaming with a weak 1 point.
14633 13 Jun 2020 @ 1816 --- cb 19.5H post eruptive. SB is gently billowing steam. All channels are dry. The water level in Cistern Spring is ~3' down from the rim of the inner tube. It has a wet water, "bath tub ring", 3 - 4" wide above the water level. It is cloudy blue in color and is very lightly steaming on the North west edge of the pool. There is an occational bubble that breaks the surface and pops.
14625 13 Jun 2020 @ 0600 13 Jun 2020 @ 0715 cb 7.5H from the start yesterday evening. NV jetting water 60'+ and SV jetting water 25'. The run off is milky white and wind direction must have pushed most of the runoff toward the boardwalk and Cistern as the boardwalk between NV runoff channel and Cistern is covered in mud, silt and debris. The boardwalk is soaked from the dip beyond Emerald to the middle platform. Cistern Spring is down 2' below overflow. It is calm and clear. 0700 SB is cycling from jetting water in both vents to steam and back to jetting water. Still is impressive 8 hours later!
14621 12 Jun 2020 @ 2200 --- hurleyintjl No eruption as of 22:00
14622 12 Jun 2020 @ 0600 12 Jun 2020 @ 2120 cb We had a few nice, stand on your feet minors, but they were brief and none of them were sustained or had good follow up.
14608 12 Jun 2020 @ 0614 12 Jun 2020 @ 0912 ypcaribou Sent a few good surges down the SV channel as seen from Steerage at 0614. Looked promising. Walked to far Back Basin after to social distance myself for a sit. From 0645 onward (as seen from far Back Basin), continued angled splashing, mostly N some S, until I left my stakeout location at 0845. Could not see details of minors from that far so will leave that for others to report. My stakeout location revealed the following observation: Blue Mud Steam Vent would audibly surge, followed by the same from Yellow Funnel Spring & Puff N Stuff (simultaneous). About 2 minutes later, SB would splash from N Vent to tree tops (as seen from far away). This possibly coincidental activity continued regularly from about 0645 to 0800 at which point traffic picked up on the main road and my pin-drop quiet location was no longer quiet. 0912 from Steerage, runoff had returned to a babbling brook.
14604 11 Jun 2020 @ 1740 11 Jun 2020 @ 2130 bbev 3D post eruption; Sv dominated most of the activity with quite a number of SVertical solo play with moderate runoff. Concerted play with tall, thickk, angled Nv, just shy of vertical. Several concerted NVertical minors during the 1900 hour, finishing at 2005 with a crowd cheering minor that failed to climb past 50', and did put the only Heavy+ runoff in my book. 2025 was last CNVSVH, followed by several SVSolo before dark.
14595 11 Jun 2020 @ 0905 11 Jun 2020 @ 1005 bbev 2D, 16 hrs post eruption; Sv active with light runoff, water trickling down shoulder and back runoff. 0912 One concerted minor with some NV "bounce" and short sustained vertical Sv. Sv dominated play for rest of the hour, no further vertical seen from either vent. CS is high and overflowing in all directions.
14590 11 Jun 2020 @ 0754 --- cb As of last nights 2D 2H post eruptive mark, water came back into SB last night (6/10) @ 1915 with a wispy 7' NV jet. Cistern Spring's pool is very high and overflowing in all directions
14572 09 Jun 2020 @ 0948 09 Jun 2020 @ 1003 bbev 16hrs post eruption; quiet and steamy, no water. CS is low, 3' below rim of "tube", no steam, no boil. water level 3" below wet line on sides of tube, and just above the cave on south side.
14568 08 Jun 2020 @ 1155 --- underarockphoto Should in basin observers get the chance; any guesses on what is causing the Steamboat-like traces on YNR? The event yesterday was pretty obviously a rainstorm/hailstorm.
14565 08 Jun 2020 @ 1048 --- WillBoekel satellite call to me saying no steamboat yet.
14562 07 Jun 2020 @ 0820 07 Jun 2020 @ 1850 bbev Radio call of good activity with vertical minors early so we packed up and went over. Frequent concerted angled minors with occasional vertical from both vents. NV more active in the morning with tall jets and wispy vertical play. SV mostly angled with maybe hourly vertical play. runoff moderate with only a few increases. Activity increased slowly over the afternoon after heavy snowfall and off and on sleet and rain. Several concerted vertical minors with increased runoff occurring hourly. 1635 was an "out of your chair" sustained minor with follow up at 1638, both given the only Heavy + ratings for runoff in my book. Concerted play continued with slight increase in frequency and decrease in vertical activity in NV. Noted that at steerage, in the trough and below the bridge, were clusters of very tiny, black, live bugs, being washed down the channel. We are referring to them as Steerage Fleas.
14555 06 Jun 2020 @ 1040 06 Jun 2020 @ 1320 RLJones Both NV & SV started showing water at 1110. By 1125 NV was having max bursts to 20ft and SV to about 8ft. At 1155 SV was having a few bursts to 10-15ft. By 1228 SV was still 10-15ft with NV still at 20ft max. Between 1155 & 1320 SV had created three light stream flows with small gravel..Color was still clear. At no time were there any vertical or near vertical plays from either vents.
14554 06 Jun 2020 @ 1045 --- RMichaels Only stayed long enough to talk with Carol and Bill Beverly and to make a brief inspection. South Vent's runoff channel is barely wet to bridge. According to Bill and Carol, water first reached the bridge about 15 min prior to my arrival. There is water in the system, but the minors I saw did not have much volume.
14553 05 Jun 2020 @ 1954 05 Jun 2020 @ 2010 bbev 2D, 4hrs post eruption: Little if any change, 2 wispy jets from NV and 1 from SV. SV runoff is bone dry.
14549 05 Jun 2020 @ 0750 05 Jun 2020 @ 0855 bbev 1D, 16hrs post eruption: NV jetting wispy 10' every 5-12 min. SV only steam and no water from vent or in runoff.
14533 04 Jun 2020 @ 1130 --- cb Steamboat is quiet, gently steaming. No sounds or water from either vent. There is some pooling of water in small depressions in the South channel otherwise that run off is dry. A. trickle of water down the north channel. There are 2 more dead trees in the north channel just below the boardwalk. FYI the Norris area lost power yesterday afternoon and is still out as of the posting.
14518 03 Jun 2020 @ 0750 03 Jun 2020 @ 0757 ypcaribou Had a good, sustained push (as seen from Steerage) about 0754 that sent a rush down to Steerage. Bigger than a brook but not yet a river. Just prior and during, the steam columns for Cistern Spring, Tantalus Geyser, Echinus Geyser, and several features in the southwest Back Basin all got noticeably VERY tall very fast. After the push, Steamboat quieted way down and the aforementioned steam columns all returned to "normal for a cool morning."
14507 02 Jun 2020 @ 1720 02 Jun 2020 @ 1831 bbev 2D, 11hrs post eruption. Splash from SV at 1725, again at 1730 SV 5' splash. 1736 NV jet to 10'. Both vents continued, individually and occasionally concerted. Several splashes reached 10' At 1820, noticed that SV runoff begining to become damp and slowly creeping down the channel. Upper 10' of channel is wet.
14490 02 Jun 2020 @ 0810 02 Jun 2020 @ 0922 ypcaribou Huffing deep in vents on arrival. First audible water inside vents at 0814. First visible water jet at 0922. (I walked to Monarch & back in between so 0922 is just first burst I personally saw when I got back.) Vent area damp, including ET & Jabba. One bbev sighting around 0800 on the walk down.
14488 02 Jun 2020 @ 0727 02 Jun 2020 @ 0750 bbev 2D, 1 hr post eruption: some deep, soft grumbling and billowing steam. CS: pool is full and overflowing as expected with gentle boil. Heavy runoff to the NW, well into the trees. Also good runoff into muddy pool and channel to the south. 0747 some huffing from both vents. No water seen in brief observation.
14477 01 Jun 2020 @ 1815 --- cb Steamboat is quiet and gently steaming. All channels are dry. The trough or what i will now call the channel is full of small rocks and debris. The big boulder that WAS in the channel is no longer there and now is off to the west side of the bridge in the grass.
14499 01 Jun 2020 @ 1737 --- ypcaribou Quietly steaming. Dead & dying trees in an approximate 200 ft radius around SB's vents. Including the one shade tree at the middle platform which is still upright but has red needles. Can now see middle platform in full from upper, trees on switchback trail to cistern thinning. Can almost see middle deck from steerage. Not yet but view up south vent channel has widened considerably.
14457 30 May 2020 @ 0545 30 May 2020 @ 1930 Suzanne More improvement from yesterday. Strong minors observed at 0629, 0810 with followup at 0817, 0919, 1247, 1544, 1545, 1547, and 1842. The series starting at 1544 was very strong with North Vent granding. But in all cases the minors ended with South Vent taking off and killing North. Several raging rivers observed throughout the day, even during the times outside of the pushes.
14252 29 May 2020 @ 0545 29 May 2020 @ 1930 hkoenig Improved from yesterday by a bit. Small pushes at 08:40 and 09:34. Then we thought we were seeing a start at 13:28. Followed up by a smaller push at 14:28. Didn't really look very good until a couple of small pushes at 17:47 and 18:14. Did notice around 15:00 that the runoff from South Vent was turning white.
14250 29 May 2020 @ 0750 --- ypcaribou "No Steamboat yet but basin smelled very sulfery when drove by." (He means more than usual.) Time approximate; texted from Cygnet Lakes trailhead at 0800.
14249 28 May 2020 @ 0545 28 May 2020 @ 1920 Suzanne Slight improvement from yesterday. South Vent had occasional heavy minors producing babbling brook, but North Vent did not show much interest until 1903 when it had a decent vertical surge (30 ft) with a follow up about 1 minute later. But afterwards activity subsided.
