Month: September 2018

After yesterday's activity, it was definitely a good time to leave. But first there was an interval of over 6 hours, so we got to see one final One Burst Grand, steamy and backlit.

Then off to Geyser Hill for a quick visit.

The sputtering under the boardwalk between Pump and Doublet was stronger than when I was there last, and there was steam coming out from both sides. I expect that walkway to close before my return. (And I was right, as we learned on the drive home that much of the area was now off limits. Gotta love the usual NPS overreaction.)

Pendant was drained, and what Micah wants to call Grove Geyser were both erupting to a few feet high. There still hadn't been a Lion eruption, although North Goggles was slowing down.

Ear seemed to have, at least for the short time we were there, settled into some strong heavy boiling. Several of the loose sinter sheet sections had dislodged and that seemed to help lower Ear's water level a bit.

Over by the boardwalk to Solitary was a strange little feature putting brownish, murky water up a foot and onto the trail occasionally.

Will be interesting to see what long-terms changes are visible here when we next visit, and what happens over the winter and into next spring.

On the drive back, did almost encounter a deer running across the road just as we were approaching Owl Canyon Road. Also saw a lot of antelope along the roads between Jeffrey City and Laramie. It must be fall.

Arrived back in the cage at midnight. It wasn't quite as cold as we'd expected, but still down near freezing. After an hour and a half we got the hot period we'd been expecting. It was a strong one, that did not include a Feather restart, instead Feather stayed on for 14m23s. But no Giant eruption. More than a little disappointing.

We'd already planned on getting up at 03:00 to leave for Norris and New Crater/Steamboat. But there wasn't much point in trying to get another nap, so instead we loaded up the truck and hit the road. Driving at that time of night can be interesting, as we found out when we came across a bison jogging north just inside the right late line, just south of the exit from the Firehole Lake Drive. Really glad I was doing Pacman and not strictly staying in my lane. (I figure if I don't see the center line when I should, it's because there's something there.)

Arrived at Norris at 04:00, and learned that a set of strong minors was in progress. It turned out that we witnessed the last of that series. By then it was really cold, but we settled in to wait for dawn and a day of waiting. Some folks who arrived later said that their vehicle thermometers were in the mid to upper 20s.

At around 06:30, suddenly the four of us had a large number of companions, all there to see New Crater/Steamboat. Most of whom I had never seen before, and from the way they were talking, they were there to add another checkmark to their personal lists. The noise level got pretty intense for that time of day.

All this time, there was nothing happening other than a lot of slopping around. It wasn't until 09:30, about 5 hours after we arrived, that we saw the next minor eruption. This was followed almost immediately but several more in quick succession, culminating with an eruption of New Crater/Steamboat at 09:36. That sudden onset was just like the previous eruption we'd seen 10 days ago.

This was a powerful eruption, but what was most notable was how it was still in water phase an hour into the eruption. That's when the North Vent shut down, followed within moments by the South vent. It was absolutely quite out there. Then just as sudden, both vents exploded upward. The North Vent looked almost as tall as the start of an eruption. South Vent was as brown as North for a few seconds,

We got 4 of these shutdowns. Then, finally, the transition to pure steam started. The water columns cleared up, but every time it looked like it was pure steam, they'd throw out some spray.

The drive back was uneventful until we got to the Mary Mountain trailhead. There traffic came to a complete stop for the better part of an hour because of a bison herd near the Kaleidoscope Group. It was really frustrating because we wanted to get back to see what had happened with Giant.

Turns out, not much. A couple of weak hot periods were inferred from the resulting puddles and pools on the platform, or from dry areas. This was interesting news. As the afternoon went on, and there wasn't any event there, it started to look like we might have a chance for an eruption.

After a bathtub, I decided that we probably had at least a couple of hours until the next event. Time to head in and start packing up to leave tomorrow. But as I was riding in, it occurred to me that if Giant was setting up to erupt, it might shorten things up. So decided I should be heading back out in about one and a quarter hours. Besides, I've been consistently overestimating how much time is available between hot periods.

The call that water was rising in Mastiff came in just as I was about to head out. I wasn't sure what to expect, so I packed for a long wait, including light and multiple layers. I quickly lightened my load and headed out. I got to the Cage in plenty of time to see the start of Giant.

The conditions were almost perfect. It was a little windy, but it was in the right direction, away from the platform, and not enough to really to chop off any height. With the low sun, there was a rainbow that was a full arc, and here the wind helped by moving spray well to the north of Bijou.

Again I tried to measure the height. This time I was back on the boardwalk, but not at the marker. That meant, at least, I didn't have to force my way to far to get there (and the decreased crowds helped.) And again I got a disappointing reading: 65%, which translates into about 130feet. The scary thing is, from that perspective, I tried to compare the height to what I remember of big (150+ ft) Grand eruptions from the same distance, and it did look comparable. Not sure what to think about this. Ideally I will try next time (and I do expect a next time or two) to be exactly at the marker and try and catch the maximum starting surge.

And Fan & Mortar erupted in the morning. No one saw it, and we probably wouldn't even have known about it if Suzanne hadn't gone down there to check on it before going to Giant. She noticed that the activity there was even worse than the last few days.

Another day of Giant hot periods about 6 hours apart. With a deadline approaching, it's not welcome.

After leaving Geyser Hill, the night before, it started to rain, and the rain continued for several hours, up until midnight and time to go back out to Giant. But when it quit, the clouds quickly cleared and the sky was bright with stars. This also meant that as we left the hot period a few hours later, it was quite foggy for the entire route.

Next morning got out to Geyser Hill. The debris and wash around Ear was impressive, although for once the NPS was quick to clean up the area, so I didn't get to see al the unnatural debris that was coughed up.

Saw a number of North Goggle minor eruptions, and the grassy areas north of the boardwalk there, as well as the new runoff from Doublet are already developing that Low-Tide Smell as the grasses are being killed. Just north of Doublet itself there was a new, small murky geyser. I confirmed the activity under the boardwalk, which also included a crack to the southwest where a frying pan was breaking out.

Sponge no longer seems to erupt. Pump seemed weak, and the slime mats around it were already drying up. Pendant and Geyser Hill #5 (the feature off in the trees north of Pendant) were both erupting, as well as the slit that broke out after the 1983 earthquake under the boardwalk. Next to the Solitary trail a formerly scummy hole was erupting, too.

Lion is also not been seen since yesterday, but Little Cub seems unchanged.

When out to Giant at 21:00 with the expectation of waiting for several hours for the next hot period. Instead, arrive with Bijou already paused, which lead into a weak 4-1/2 minute Feather and Feather Satellite eruption. This was interesting, as it was starting to fit the pattern that lead up to the last Giant eruption. So went back in to get a nap and return at midnight.

Ended up waiting for four hours, until 02:00, for the next Giant hot period. This was a pretty strong one, where Feather did not have to restart, and Giant did have some, but not a lot, of surging at the right time. Because of the cold, it was impossible to see much on the platform once things got started, especially back through the Mastiff runoff. But with several of the bright lights, we could see Feather and Giant itself.

Because the duration of the previous Fountain Geyser eruption had been reported as 36 minutes, we then went out to check on Fountain and Morning. That longer duration is one of the few signs that Morning might erupt soon.

It was a slow drive because we didn't want to have any close bison encounters. Got there to find that we'd missed Fountain by at least an hour, but at least we confirmed that Morning probably didn't do anything.

It appears Giant has settled into a mode it displayed last interval-- for several days we get a moderatly strong hot period every 6 to 7 hours. In between there may be a bathtub or weak Feather-only hot period. If this is the case, then any hope for a short interval (and for an eruption before we leave) is gone.

But the big news were the massive changes to the northern third of Geyser Hill, which started with a huge eruption of Ear Spring. I was hanging around waiting for the latest Giant hot period, so I didn't get over there until dark. But it was still obvious that things were different. I saw the murky mess in and around Ear. Both vents of Doublet were erupting to several feet. There was an Aurum eruption only a few hours after the previous. And under the boardwalk between Doublet and Pump there was the sound of either a frying pan or a drain hole (hard to tell in the windy conditions). Pump itself seemed weaker.

In any case, will have to visit again in the morning when can actually see things.

After last night's strong hot period, decided that getting some sleep would be a good idea. Got back out about seven hours later and it seemed pretty clear that nothing much had happened. At best, there's been some Southwest Vents activity hours earlier. So it was just a matter of waiting.

Almost immediately we got a Bijou pause lasting about 4 minutes. Since it was time for Grand, and nothing was going to happen for about a hour, it was a good time to go there. I saw the start from near Wave Spring, very nicely backlit from that vantage point. Unfortunately, it was a short One Burst Grand.

Back at Giant, waited through a series of pauses, including one that lasted about 3-1/2 minutes. An hour later, we got what we'd been waiting for. This hot period did not have a restart. While there was some nice surging in Giant, far too much of it was just bigger versions of the normal surging, and that generally doesn't lead into an eruption.

The afternoon Grand did have a second burst. It was only a little over ten minutes long, so years ago a third burst could've been expected. Instead, Vent and Turban quit as if it had been a much longer interval.

Up to this point, about 5 hours after the hot period, it had been fairly calm. Now the winds picked up, despite the warming day. But didn't spend much time in it since the next weak hot period was right afterwards, and then missed the a stronger one a few hours later.

Coming back from the missed hot period was something different. After getting past a bison moving fairly rapidly (for a bison) from the Inn parking lot toward the Lower Store, I heard a commotion over in the Old Faithful circle. There was someone standing right out on the cone, oblivious to people, including NPS personnel, yelling at him to get back. At one point he lay down with his upper torso over the rim, and tried to climb in. Finally he wandered slowly back toward the Lodge.

I bicycled over there and caught a glimpse of him as Law Enforcement tried to make contact. He seemed in a different reality, and the facial tattoos gave the message that he'd had earlier encounters with the law. He never did cooperate, and was arrested in the Lodge parking lot. I'm sure he enjoyed coming down in the Mammoth jail.

Did a repeat at sunset, with a Grand eruption followed by a weak hot period. So went in to wait for a few hours before heading out to wait. Ended up being out there until well after midnight.

One thing we've noticed over the past few days is that Grand seems to be having more two burst eruptions. Thanks to Giant hot periods, I've missed a few of these. But a number of them have also been of the Long Second variety. The pause comes fairly early, before the 9 minute mark. But once the height of the second drops, Grand seems to go almost immediately into Big Sawmill mode.

I've thought that all the one bursts are because Grand is too strong to quit, so we never get the pauses as before. The Big Sawmill mode fits in, in that the eruption is wasting energy and water so when it does stop, it can't restart. The Long Second mode fits, as it's just weak enough to pause, but still stronger than it used to be and goes back into splashing around.

It was a day of watching Giant. The hot periods became stronger as the day progressed, with one that could've resulted in an eruption shortly after midnight. But it didn't, and we still haven't had one where there wasn't a restart.

In the cabin area the last couple of nights I've heard either an elk or a very squeaky door hinge.

Another time that we'd planned for an early trip to Norris, only to wake up and discover there's no need to go. In this case, the eruption of New Crater/Steamboat was either too late or too early. Too late in that there's no way we'd have spent over eight hours in the dark waiting for it. Too early because it erupted before we even had a chance to hit the road.

So it was a day to start watching Giant, even though the four day mark wasn't until near sunset. Got to see a fairly strong hot period around 10:30, then over seven hours later there was a fairly weak one with only Feather and its Satellite.

After dark, four hours later, we pretty much got the same hot period. With it supposed to be wet, I wasn't going to be out in the dark.

With it being really too early for both Giant and New Crater/Steamboat to erupt, it was a day to do other things. In this case, do the northern loop and visit Canyon and Mammoth. At the latter, also got a tour of the Reamer House in addition to walking the Lower Terrace loop.

Did get out for the early night One Burst Grand, just because it was fairly warm and Grand has been so predictable when it comes to intervals.

Beehive had a reasonable 15 hour interval, but a one minute indicator was enough time for me to grab what I needed and start to shut the cabin door. I just went back to what I was doing. Probably a good thing, as it was so windy that I couldn't have gotten closer than Sulphide Spring without getting drenched.

Saw two Grand eruptions. The later one was a One Burst Grand, but the first was more interesting. The first burst lasted a bit over ten minutes, which usually means that that's it. But this time the water stayed up, and even though it took a while to get going, we got a second. Then it turned into a long second, with a total duration of almost 13-1/4 minutes. It looked like Turban had quit before Grand did, and during the last minute of the eruption Vent was nothing but steam.

Spent some time watching weak activity at Fan & Mortar. It looked a lot like when it is dormant and you know the cycles aren't going to be strong and there's not going to be an eruption, no matter how good they look when Gold comes on. But during that sort time, there was quite a bit of stupidity.

First there was the European couple who not once, but twice had to get pictures of Norris Pool from beyond the railings.

Then there was the guy who sat down next to me and saw a "frog" in the formations around Mortar. He was going to show his family where it was by bending over and picking up a rock and throwing it. I stopped him before the rock flew. He insisted he wasn't going to do that, but he never once looked at the rock he did pick up and let the rock fall out of his hand.

Then there were the Earth Units (probably American) who first had to get a picture of one of their group straddling Link's runoff at the bridge during a minor eruption. They then went on down south, near to where the runoff first enters the gutter and one of the group jumped across the runoff. That finally got a reaction, and he immediately leaped back over the runoff.

Then there were the two Chinese women who thought it would be a great idea to do a stupid pose using the bikes in the bike rack. I heard a lot of rattling noise back there, and in no uncertain terms told them leave my stuff alone. Instead of the usual Asian giggle, one of them actually tried to excuse their behavior with "it's not hurting anyone." Yeah, right, you let people mess with your stuff all the time.

They got down to Norris pool, and the objector immediately heads off around the railing. That got them even more berating. How much stupidity did those two engage in while getting that far down basin? I don't wanna know...

It's almost like there is a constant number of stupid people visiting the area, and now that most of those who can behave themselves are gone for the season, the stupidity become even more intrusive.

Later on, decided that it would be a good night to see Grand, which haven't done in a while. It was actually a fairly warm night, with no wind. The lack of wind meant that the two bursts were pretty much obscured by their steam and that from the runoff.

Another quiet day. Saw a couple of Grand eruptions, even got a second burst for one of them. Spent time at Fan & Mortar mostly to kill time.

After the second Grand, headed out to Imperial Geyser at 17:00. The parking lot was crowded, but all those people were on a quest to fill one more item on their bucket list. Beyond the overlook we met a few people coming back. Beyond Fairy Falls we encountered three employees who were at the top of the butte when we arrived at Imperial. (How do I know they were employees? They were hitchhiking back from the parking lot as we left.)

This is the first time I haven't gone out there in the morning, so was a different experience. The lighting and lack of steam made Imperial's activity even more impressive. The runoff channel, based on the dead trees that aren't being flooded, has shifted a few times lately. Only watched Spray for a bit, but did see both vents active (the one on the right doing most of the work, but on the left splashing to a foot or so.)

We were the last out of the area, and there was only one other vehicle in the parking lot when we left.
