Observations for 19 May 2013


Maybe I should have gone out the night before. I woke up at dawn and headed out. The rains had stopped recently, and considering what it could have been like, it was kinda nice. I was pleased to see that there wasn't much steam at Grand, so at least I hadn't just missed an eruption.

As I got closer,I found that the reason there was no steam was because the crater was totally empty. Vent and Turban had quit a while earlier, and the eruption was from one to two hours ago. That meant that overnight, there was either a long interval, or a couple of eruptions in less than 12 hours. Would have to factor that into the plans for the rest of the trip.

The Sawmill Group had also just ended a deep draining eruption by Sawmill. Uncertain was gurgling a bit, but not enough to make it with sticking around. But Castle did start up, and despite the gray sky background, the rumbling and column of the steam phase were nice. By that time, it was starting to drizzle again.

Headed in to take a nap, and when it was time to go out to Grand again, the rain was coming down as wet white flakes.

At least those turned into a sort of drizzle that persisted the rest of the morning. Didn't really need the umbrella, as it wasn't really getting much wetter, but the umbrella did function as a sort of wind-break. The wind was strong enough to have appeared to have delayed Daisy during that time.

Grand was not showing any sort of inclination to erupt when West Triplet started. Grand still didn't look any more promising when Beehive's Indicator was announced. That cleared the benches, so there were only a few to see Rift start. So I was pleasantly surprised when about 1/2 after Rift started, Grand definitely had waves and then erupted. Was a nice two burst with enough contrast between the steam and the clouds, and enough wind to see the jets separate from the steam.

During the eruption, Rift also quit, with a duration of somewhere between 30 and 40 minutes. A bit short, but the first one I've seen this year.

Since Grand had had several short intervals lately, decided that I should be there at around the six hour mark. The weather was acceptable, with only a drizzle, not enough to require use of the umbrella. But as the wait progressed, the drizzle turned into sprinkles and by the time Grand erupted, it was raining. Grand seemed to ignore the West Triplet eruption, and we didn't get another short interval, unfortunately. At least it was a long one burst eruption.

Afterwards, I noticed that Penta was looking really good. The bottom vents pool was full, and might even have been overflowing. WIth the rain it was hard to tell that, or if there was any upwelling over the vents. Spasmodic was full, as was Sawmill, which might even have also been in overflow. But it was so wet it was hard to tell, and I was so wet myself I decided to let the marker catch the eruption, and came on in.

But at least the cafeteria has Bison Meatloaf back on the menu

Observations for 18 May 2013


Coming in from the West Entrance, and knowing that Grand probably wouldn't erupt for several hours, I had no excuse not to stop at the Fountain Paint Pots and take a look around. Got to see an empty craters for both Fountain and Morning. Even with the overnight rain, it was pretty obvious that it was a lot wetter around Fountain that back around Morning. Jet huffed and puffed, but didn't erupt while I was there. I did get to see several boils in the 3/4 meter range on Celestine.

By the time I got to the Upper Basin, the rains were starting to pick up again, just enough to be constantly annoying. Which seemed like it would be the theme of the weekend. Sawmill was pounding away, and it seemed obvious that the group was going into a drain mode. This was confirmed when Penta had a weak steam phase eruption. shortly before Sawmill quit.

Grand had a couple of desultory Turban eruptions, which were followed by a Vent overflow. The pool never looked good through the fog. A couple of quick 16 minute Turban intervals we got a nice, but short one burst eruption.

By then the rains had stopped, so I decided to take the opportunity to run down basin. It might the only dry opportunity. That it was also about time for Daisy was another good reason. The Daisy eruption was typical for the last decade in my experience-- a duration of 3m24s. Splendid shows no signs of any overflow to the north, not even from Daisy eruption water.

Fan & Mortar showed that they can still look really good for a few minutes when the Fan vents start up. But about three minutes later, that activity had died down and the Angle Vent had started.

Geyser Hill from the parking lot can be really boring without Plume, and during the long pause between Lion series. I saw nothing over several hours of killing time but an Aurum eruption.

I finally got checked into my cabin and things unloaded, and was about to change into warmer clothing when I heard the call that Grand was erupting. An interval well under 6-1/2 hours was not what I was expecting. I decided that I should at least make an attempt to see something, so biked down and was walking down from Crested when the long one-burst eruption finally ended.

A bit later in the evening I did get to see an eruption of Beehive as the rains started to return. I considered going out to Grand, if the intervals were going to be short, then maybe there wouldn't be a wait, but it was still sprinkling, and decided I wasn't up for a cold wet wait in the dark.
