Category: Activity Report

If I hadn't known that it had erupted the day before (at 14:33 on 02 July), I could have been fooled by Fan & Mortar's behavior this morning. Around 06:00, only about 16 hours after the eruption, I got to see a perfect example of post-eruption type activity. The water levels are low, which seems to make the normal splashing and surging that F&M are always doing even more vigorous. During the fifteen minutes I was there, Mortar's Bottom Vent was erupting most of the time, with some bursts to two meters. This produced overflow  down the various catchbasins and into the river. On the Fan side, the Main Vent as the star. As it always does, the surging in the two geysers dies down only to be followed by a quick restart. A number of these restarts were accompanied by Main Vent splashing well above its rim accompanied by explosive sounds. But none of the other signs of high water were there, so time to move on.

Grand appears to have had two long intervals in a row. The second, daytime one was accompanied by Rift. The Turban intervals leading up to the eruption started long but after a couple got progressively shorter until dropping just under 17 minutes. Some of the sputs between Rift and Grand have reactivated, but have only been seen for a few minutes, unlike past years when they could be active most any time.

Giant is dead for now. The platform was mostly dry. I was told that the puddles that I did see were probably due to huge cone-filling surges out the front that look impressive, but mean little. Mastiff is having the same sort of activity, but there are no real hot periods any more. Some day this summer, it's just going to erupt without warning, just like it's done in past slowdown years.

For a short trip, it doesn't make sense to not take advantage of a geyser I wouldn't put in the same effort if I were here for weeks or months. Since it was obvious that Grand wasn't going to be anytime soon, I went to Geyser Hill and waited for Beehive. Perfect conditions, dead calm but warm enough that the steam wasn't obscuring. I was able to stand on the boardwalk closest to the cone and see a double 210° rainbow, and only get wet once. (But the umbrella served its purpose there.) I may even have to visit the Lower Basin.

After a string of single burst eruptions, this morning it tossed in a three. And considering the weather, it was pretty good: no rain and calm. Also the sky behind the water column provided some contrast making the water column visible. But following the eruption, I was left with the bigger question— what to do next? By 09:00 it was obvious that the best choice was to head home.

I think I need to get over to Geyser Hill more. Shortly after making the last posting, I talked with Scott Bryan who informed me that the water level I'd seen in Vault was normal, at least for the last few years. It dropped to that level a few years ago after a series of independent Vault eruptions.

It's a lot easier going out into a cold, rainy day when you've got a good night's sleep. The early morning Grand eruption of course started just as the rain picked up, and the rain ended soon after Grand did.

The channel leading to the new drain for Old Tardy's runoff appears to be wider and deeper than it was last week. The hole itself doesn't seem much changed, but I have yet to see Old Tardy in eruption, either. The vents by the bridge aren't as murky as yesterday. I'm assuming that that means there's not been an eruption recently. (Alternative is that they are erupting frequently enough to start to clear out the system.)

The river seems higher and murkier than it had been yeserday, but I guess the cold, steady rain is having its effect.

Probably the best indication that Giant is not going to erupt soon is that all the people who in previous Mays (or previous days) would have made an effort to go down and wait for something to happen instead today went to see Great Fountain. (You know the basin is empty when no one reports a Plume eruption on the radios.) Not that that wasn't a good decision. I killed an hour down there. The amount of splashing from Giant is impressive. On several occasions it slopped out the front, leaving a steaming pool at the base of the cone that could almost have been mistaken for the result of hot period activity. But when it came time for the hot period, everything looked wrong. The southwestern platform vents preceded Feather by over a minute. Bijou didn't even try to slow down. If it had any reaction to the hot period, it didn't show it until the end. That's when it went into a nice steam phase which in previous years would have followed an eight to ten minute long hot period. Otherwise, Bijou reminds me of its appearance back in the 1980s.

Since it seems a waste to be here for only a couple of days and not be out and about, I decided that I should make an effort to visit various parts of the basin. Another sign of how dull things were is that I did something I probably haven't done in close to two decades. I waited for an eruption of Riverside. It was too steamy to see much, so maybe it shouldn't count.

Paid a visit to Geyser Hill: walk the loop, catch a Plume and get lucky with anything else. In this case, got to see a nice eruption of Lion that started while I was down by Depression. (There was an Aurum while I was at Plume, but that doesn't count.) But what I found interesting is that both Vault and Infant were down about 3 inches from their respective rims. It seems a bit long for them to have not recovered from the Giantess eruption. Or have my Geyser Hill visits been so rare that I no longer even know what is normal for them?

While waiting for the late evening Grand eruption, I got to witness a perfect example of how people get themselves lost.

The sun had already set but it still wasn't totally dark. There were three other people besides me waiting for the eruption, when up from the Sawmill Group up walked a man. From accent it was obvious that his native language came from somewhere in East Asia. But language didn't seem to be an issue. He asked the couple, "is this the way to Old Faithful?"

Now at this point all that could be seen down basin were the whitish splotches of various steam clouds. Behind him were all the lit up buildings of the Old Faithful area. He was told, no, you need to go back the way you came. But he insisted that he needed to keep heading downbasin, despite repeated attempts to make clear that he was wrong.

The second woman waiting even gave him simple instructions, "go back to the junction, go right across the river to the paved trail, then left towards the lights." The last we saw of him, he was headed towards Geyser Hill.

The man asked for information and directions multiple times, yet every time he got an answer that he didn't like, or didn't fit what he needed to hear, he'd asked again. It would seem obvious with it getting dark that the way to civilization was toward the lights, yet he wanted to go farther into the dark. Why did he bother to ask us when he wasn't prepared to listen? What would he have done, how far downbasin would he have gotten, if no one had been waiting at Grand?

Today showed a number of the ways that things can go wrong on a weekend trip, or at least how they can not be as good as they could be. Nothing catastrophic, like for last year when my old truck immediately needed repairs the day I arrived. Just a bunch of annoyances.

First, I left from home too soon, so I arrived in the park while it was still dark. I'd forgotten what nighttime driving here can be like. It's something I've never liked it, even if it's the one time of day that the roads are free of other vehicles. The odds of meeting up with a bison are just too great. To make things worse, there was thick fog almost the entire way from West Yellowstone. Doing 30mph was more than fast enough, but some stretches, like the Firehole south of the canyon until the Lower Basin, seemed to go forever.

And the bison still made their presence felt. There must have been a large herd using the road as a trail just a few hours earlier, because the lower part of my truck behind each wheel on the left side was thick with manure. I will definitely be visiting a carwash when I get home.

So I figure the best time to arrive would be just before sunrise.It will be light, but before the bison and most visitors are up and about and blocking the road. Last weekend I arrived after the ranger-in-a-box went on duty, and had to deal with both varieties of obstruction. I want to set up a nice routine that gets followed every trip, so I keep the thinking about it to a minimum. (The same goes for prepacking needed items not used at home, and making checklists for the stuff that I need to gather up.)

The weather wasn't nice either. The fog turned into gray overcast skies, which turned into precipitation. Unfortunately, it warmed up just enough so that it was rain and not snow. This continued off an on all afternoon, although it could actually be nice when the sun broke through and the wind died down With a limited amount of time, it seems a waste to be sitting and waiting to go out, but if there is nothing to wait for, there's also no point in getting soaked and chilled. This was typical weather for late spring, and one of the reasons I have usually avoided long visits this time of year. (Last year being an exception due to job commitments that worked out well.) I knew from the forecast it was going to be scattered rain. Just means in future years, springtime trips will be limited and subject to cancellation.

Then there were the petty annoyances: I broke the wire on the bike's odometer. It's horrible not knowing how far I've gone and how fast I'm going. On the other hand, I can get it fixed or replaced before the next trip, and will also figure out how to prevent it from happening again.

Perhaps for the best to get all these things out of the way. It does help set a baseline for what to expect, and I always prefer being pleasantly surprised when things go right. Having to use the rain and cold weather gear did show that I'd packed the right items And I've got another day and a half this trip, in which thngs can go either right or wrongl
.

And what about the geysers themselves? I saw another Penta, which is always nice, even if I missed the start. On my way there I finally got to see activity in those features on the other side of Sawmill's runoff at the end of the bridge. I'd seen it before, sometime in the early '90s, but that had been from the walkway just below Crested. This eruption only lasted 39 seconds, so you've really got to be there to see it. The second vent between it and the river drained, then refilled to the rim only to drop down a foot. The water also turned a milky white in all the vents. During the Penta eruption, Churn filled as the rest of the group dropped, but no eruption.

There's also a new feature over on Geyser Hill at the north of that expanse of sputs between Depression and Arrowhead. At least I've never seen it before, and didn't see it last week. I really should try to get to Geyser Hill more often,and for more than just Beehive, especially since it's an easy walk from the Lodge Cabins. There's something about not being able to bike over there that keeps me away.

Grand at least waited until I could get out there this morning. I caught the end of Rift, which was probably the reason. The next Grand was during one of the aforementioned rainstorms. I tried to catch Daisy but a wind shift meant I saw a lot of steam, and not much Daisy. Giant is going to be a great timewaster for the next few weeks. It looks so impressive with all the activity until you realize its been essentially unchanged all month.

After returning from last night's Grand eruption, I figured that today not only could I get a slow start, but would have several hours to head down basin to take a look at Daisy, Grotto, Giant and other points of interest. Except it didn't turn out that way.

As I was getting up and about in my cabin, I heard Scott's voice on the radio announcing that Penta was in eruption at 06:44. Knowing that most eruptions of Penta last well short of an hour, I was resigned to not seeing it erupting. So I was surprised when I biked up past Castle and there it was, still going strong at 07:30. I figured I had at least an hour before it was time for Daisy, so I could head over there and catch Penta draining away. Instead, it just kept going, with all the other members of the Sawmill Group full.

Penta, Sawmill & Churn Geysers, 2008 May 18

It was at the time that I noticed that the overflow of the vents by the Thumping Hole had ceased that I looked over and caught Churn in eruption. It had been going for a while, and like yesterday, wasn't able to get a picture. But now things were getting interesting, but at the same time, my plans for the morning were ruined. Unlike yesterday, Churn didn't have a series of eruptions. A hour later, however, Sawmill started. I wanted to get pictures of both Penta and Sawmill in eruption from several angle. I went down towards Belgian, and right after I turned around, I saw the first splashes from Churn. Gettting all three into a single frame with my ancient camera was a bit of a challenge, and you can see my best efforts aren't that good.

The Churn eruption seems have been the key to getting Penta to finally quit. As the window for the next Grand eruption was approaching, I took the opportunity to head back to the gas station to prepare for another wait. Sawmill was still going as I returned, but as it seems to do far too often, it quit about the time I passed Scallloped Spring.

Speaking of Grand. Both last night and today's series of Turban eruptions were quite similar. In both cases there was a "Two Turban Delay". Instead of heavy overflow and waves as in years past, in these cases there was visible bubbling in Vent along with what appeared to be a full pool. In both cases, the duration of Turban was short (less than 4 minutes) despite what appeared to be vigorous activity. The following Turban intervals were short, around 17 to 18 minutes, with the Turban eruption lasting around 6 minutes, which is typical activity in such a delay mode. The bubbling in Vent is hard to see unless you know where to look and what to look for, but I wouldn't mind if this became a preferred delay mode. (Sure beats the 7 Turban Delay which takes 10 or more...)

The photos of the new drain vent near Old Tardy will have to wait until tomorrow. I've discovered that, thanks to software upgrades in the last year, I only have one computer that can still read the old Kodak KDC format. And that requires and it can't connect directly to the computer I use to post these messages. So it's become a convoluted task, and probably the incentive I need to finally get a new camera.

I also confirmed that, with my iPhone, I can add geyser eruption times to my Geyser Log database while in the basin and during the actual eruption. The speed is modem-slow, but I can make things a little faster/better by changing around the webpage.

The drive home was exactly what was expected: 6 hours of dullness that ended in my garage.

A weekend visits to the park is always different than a long stay. They always seem to feel too hectic,at least for me, and I've always prefered the long stays. It's okay to miss the an eruption that takes place as you arrive, whereas with a weekend, that's a significant portion of what you came for. But when a weekend is all you can get, you take it. Earlier in the week it became farily obvious that this was going to be a really nice couple of days, perhaps the best of the spring, and a good time to figure out how to prepare for future weekend trips this summer. What t I didn't count on were the bears getting in the way.

The entire basin was closed yesterday because there were a couple of bears seen roaming about, including one which earlier in the week had take down a baby bison in full view of visitors up on Geyser Hill. So when I arrived, tthat closure was still in effect, and the choices for what to do were severly limited. I decided the Beehive overlook was the best place to spend my exile. The advantages are that it is near something erupting (Geyser Hill), you can see most features down basin (at least their steam clouds), and Beehive was probably going to erupt this morning. Fortunately, the three hours I spent there resulted in my missing nothing interesting down basin, as Castle had a minor as I arrived and Grand waited until well after the opening. (The less said of Giant and Fan & Mortar, the better.)

The indicator preceded the 10:39 Beehive eruption by only 19 seconds, and was maybe a couple of feet high at most. Beehive was already sloshing heavily when it started, and it quit moments after it became obvious that Beehive was in eruption. It did awaken for a bit later in the eruption, but due to the wind, I was not in a position to see much of it. So while Beehive has been fairly reliable erupting every day, the amount of actual warning you get may be none.

The Sawmill Group was interesting, too. During my exile, I noticed that Tardy was always on every time I looked down basin. So the wet runoff channels but dropping pools was no surprise. Looked like Penta might have a chance during the next cycle. Instead, as I was leaving the area, I saw Churn erupt for the first of three eruptions in the series. The first eruption even had that dead fish smell even though I was told that Churn had been active earlier in the week. During that same series, I saw a Bulger major, the first one I've probably seen since the 1990s.

Penta was not to be, however, as the pool levels didn't look right and Sawmill had a steady stream of small bubbles reaching the slowly rising surface. Sure enough, Sawmill began eruting while well below overflow.

Even worse, Rift started an eruption while I was there. I didn't see when West Triplet started, but it was active when Rift started, but quite within a few minutes of Rift's start. It seems typical of the Grand Group for West Triplet and Rift to reactivate in mid-to-late May, but why can't it ever wait until after I get to see West Triplet as an intermittent spring?

But the most intriguing thing is a new hole in the Old Tardy runoff channel, just before it joins the Crystal Spring/Slurp runoff. THis hole is about 8--12 inches across, and has that same layered appearance that the holes near Scalloped Spring exhibit. When I first saw it, I thought that it might have been a feature that appeared over the winter, but Scott Bryan said that it wasn't there when he was in the basin on Thursday. From where the ground is wet or dry, it appears that it might be a drain for all of the Old Tardy runoff that used to flow in that direction. Years ago there were some patches of steaming ground around Old Tardy. I'll have to go through my old notebooks to find the maps to see if any of those places correspond with this hole. (And I'll try to post pictures of it tomorrow.)

There's a lot of snow still on the ground. Coming in through Island Park, it seemed that if there wasn't snow, then there was standing water But the Madison and Firehole Rivers don't seem all that high, at least compared to some of the seasons I remember. The shelf in the Firehole at the Sawmill Bridge is just barely under water. So perhaps the worst is yet to come. (And if there's standing water around here like there is in Island Park, gonna be a long, nasty mosquito season.

This morning the webcamera shows an eruption of Giantess, the first eruption in about 22 months. Based on the nature of the play from Giantess, and that I think I saw activity in Vault, it appears that the eruption started in the early morning hours.

Update: 10:45

Well, it appears that the activity was the final stages of a steam-phase eruption that started early last night (say around 22:00). The OFVC seismograph should have the start time, so let's see how wrong I am.

Mary Beth Schwarz reports that since I've left, the mode shift at Grand continues. There have been several more false Vent overflow delays, and then yesterday (04 July) Grand had it's first known "boop" delay in several years. (A "boop" is when, during a Turban heavy overflow delay, Grand has boiling to up to several feet over its vent which does not result in an eruption. )Like the false Vent overflows, this usually results in several Turban interval delays.In this case, six. Fortunately, the delay took place early in the Grand interval, which kept that interval from being excessively long.

Grand decided that it needs to not only have more long intervals, but to resurrect a pattern I've not seen this trip: the one where every Turban interval is about 30 seconds shorter than the previous,and Grand won't even try to erupt until there's an interval of about 17 minutes or so. And even then, there's no guarantee that you won't just get some sort of Turban delay. But this time everything cooperated and we got a less than ten minute long two burst eruption.

Then while starting to pack up the truck for the trip back, I got a bonus. Haven't really seen Beehive all trip, because so many of the eruptions have been without the Indicator. The previous eruption someone announced that water was rising in the Indicator, and within a minute, Beehive was in eruption. I was in my cabin, and barely got out the door from one radio call to the next. Weeks ago I'd resigned myself to seeing Beehive no closer than from the river overlook, if I was lucky.

Today we got another such call, but this time the Indicator cooperated. I was able to walk fast and get to about Anemone when Beehive took off. With the prevailing winds, that meant I was on the wrong side, and took the cold drenching to get to the other side. There were full 360° rainbows in there somewhere, but I didn't stick around for them. That water was cold. I wish I'd brought the camera, because not only was that the first time I've seen the Second Indicator, for much of the eruption it appeared taller than the Indicator itself. And I still don't know who exactly it was who gave out the call.

Elk below Castle Geyser

For the second afternoon in a row, Grand had a false Vent overflow. Today at least Grand finally did erupt during West Triplet, but I don't like this sort of behavior, and almost thankful that I won't be around to have it frustrate me. While waiting, we did have a herd of elk and their calves appear below Castle and head off across the walkway and north.

Lately Grand has been having a long interval followed by a couple of shorts, or some sort of variation on the theme (like two longs in a row, or three shorts, etc.) Today it tried something different. The early morning interval was a long, so I expected a short. Instead we got one of the longest intervals of my stay. It seemed to break all the rules. We had a false Vent overflow, West Triplet erupted a second time without Grand following along, and had several short (under 17 minute) Turban intervals, and Grand finally initiated the eruption for The Burst and Quit. It was a hot day and fun was had all around.

At least it kept to form for the nighttime eruption, with a little over seven hour interval putting the start in the second minute of July. But what I don't understand is why tourists come out on a moonlit night and then proceed to wave weak flashlights at the eruption. Fortunately the moon was so bright that they didn't matter.

Coming back from downbasin, I always look over on Geyser Hill as I bike up that well-despised hill the Inn sits on. It's mostly to check for a Beehive Indicator, but occasionally I do get to see something else of interest. This morning, after Grand, I noticed that Giantess was putting up a strong, well defined steam cloud. Now it was around 08:45, which is a bit late for any dry ice effects, but the last few days we've been having calm mornings, and those are excellent conditions for Giantess to have its big boils. Not making any predictions, but just noting that this is the first time that I've seen anything at all from that pool.

The second burst of the mid-day Grand eruption was had a long second burst that featured lots of Big Sawmill action. During the last half minute, Vent was reduced to a steam jet with little to no water visible. The post-eruption pause, at over 23 minutes, was unusually long, too.

I was a bit surprised that for a Grand eruption that would take place just after sunset with a full moon in warm conditions, there were just a few tourists out beside me. No gazers or even geyser groupies. I remember years past where there would have been a dozen or so of us out there. Then again, most of those people have gone, been driven away, or gotten older. But still, you'd think that some of the newer gazers would take advantage of such opportunities.

Thanks to Grand once again deciding to have a long interval when it could instead have erupted by moonlight, I got to see that Grotto was still in its marathon eruption when I left at 04:30. Which, it turns out, was just about the time it shut down. Grotto was off and dead by 05:20. So once again, the Bijou Monkey Cage would be filling mid-morning and overflowing by noon. Grand had a consecutive long interval, and despite the breeze, it was a hot wait there.

Mastiff Geyser 2007 Jun 28 12:31

Had already decided earlier in the week that if a Giant hot period started while I was at Grand, I was not going to race down to the Cage with the rest of the herd, but stay there and, should it actually erupt, try and get some photos, and get to see what it looks like from there. Today I got my chance. Unfortunately, some of the pictures were blurred because I was in such a hurry and the camera is so slow to respond. As with last week, the time between the start of Mastiff's surging turning into actual jetting until the start of Giant seemed to last forever, despite it being just a bit under two minutes.

Giant Geyser 2007 Jun 28 12:33 from Grand and Oblong

Giant signs

I do sort of wish that the circumstances of the two eruptions, this one and last week's, were reversed, as I'd really have liked to have heard just how high this one was. It was definitely larger that earlier, but by how much? (Maybe someday, instead of immediately yakking into their cell phones from within the Monkey Cage every time, some people can put the effort into seeing and recording eruptions from other locations like I've tried to do. And I do resent, just a bit, how a number of geyser groupies just assumed I'd be measuring this height like last time.)

The Grotto that started the night before didn't last, so when I came out for the middle of the night Grand, nothing much was happening down there. Giant's platform looked like there hadn't been an event in hours. Thanks to Grand having a 9 hour interval, I got to see the platform again, when it looked unchanged just before a short, weak hot period. But then Grotto started, and it became apparant that this was going to be the hoped for marathon.

Morning's Thief 27 Jun 2007

The marathon meant that it was possible to be elsewhere, and I was able to fulfill other obligations, as the photo shows. I'm told that while I was gone, Beehive had an eruption that was actually preceded by the Indicator. That evening, thirteen hours after the start, Grotto was still erupting.

The marathon quit shortly after sunrise, setting things up for an afternoon of Giant. A short afternoon, as the hot period took place at 12:44. It was disappointing because it didn't last long (about 9 minutes) and did not feature much in the way of Mastiff activity. And then the hourly hot periods resumed with a Mastiff bathtub.

That activity continued, with the last daylight hot period actually the best of the day, and in some ways better than the recovery hot period. Grotto also started only about a half hour earlier, so it was hoped that it was a new marathon starting, and this all meant everyone could get a good night's rest.

Grand finally almost cooperated by erupting just before sunset, with the light disappearing late in the eruption. There was a particularly intense rainbow coming straight out of Vent when you stood in the right location. It would cooperated better if it had had a second burst.

Turns out it was a mistake. Spent a whole night, and the next day, seeing weak hot periods and short Grotto eruptions. Grotto finally went into a marathon at 14:35, and Giant had the big hot period we'd been expecting for 36 hours shortly after that. The first six minutes of it seemed fairly ordinary, the only distinguishing feature being a number of previously quiet vents were active. Then, several minutes after Feather had quit, it restarted and Giant started massive surging. So much so that observers there insisted Giant was about to start. Unfortunately, it didn't, and now we wait out the marathon.

Grand seems to like having short intervals during the evening, night and early mornings, reserving the longer intervals for mid day when the crowds are the largest. The morning eruption was right at the time when the sun was appearing over the trees, so that only the tops of the jets, and the mass of the second burst were illuminated.

Another pretty dull day, with lots of weak Giant hot periods and waiting for Grotto to do something. But as the day progressed, the amount of surging in Giant and Mastiff got stronger. Made it easy to believe that something might happen, and soon.
