Observations for 2026 June 06


Not as cold as expected, as clouds moved in during the night, and it was overcast at dawn when I went back out to Grand. Arrived to find West Triplet in eruption. Spent the next 2-1/2 hours waiting for the next West Triplet eruption as Turban had a series of varying strength eruption.

West Triplet started again just before the Grand One Burst Eruption. It was calm, so there was a nice base surge rolling across the runoff channels at the start. The eruption was followed by an eruption of Rift.

Then it was off to Geyser Hill as Beehive had not yet erupted. Got over there and after killing some time, thought about waiting over at Aurum in case it erupted. Instead at that point water appeared in the Indicator, and shortly afterward, like yesterday, Aurum erupted while Beehive's Indicator was erupting. So if I had gone over to Aurum, I probably would have missed the eruption while en route past Lion.

With the wind, the best view of Beehive was from near Plume. Not the full arc like yesterday, but still strong and double.

The wind blew the spray from Beehive all over the area around Scissors. When I went past shortly after Beehive's eruption ended, Scissor was completely quiet. I wasn't able to get a photo at that time (too many people milling about), and when I tried again a few minutes later, Scissors was back to normal.

Went up to look at the various holes and features around to the left of Sponge. I noticed that Sponge itself was having periodic overflow eruptions, but never dropped out of sight. Dropping out of sight is what I remember from a few years ago. Then waited around and eventually saw an eruption of Slot Geyser.

That's when the fun began. Old Faithful started to erupt, after a nearly two hour long interval. Then we noticed a bison passing by Doublet headed our way. We quickly cleared out as the bison crossed the boardwalk by Pump, then broke through the crust. It continued on, again crossing the boardwalk to the left of Sponge. Out in the flat it broke through again, but continued to plod along. We started moving in order to beat it to the junction by Sulphide. Fortunately, it found some tasty grass below Giantess. By that time we were ahead of it, but the crowd from Old Faithful was starting to appear. None of us wanted to hang around considering that bison/touron interactions were bound to occur soon. Fortunately, on the other side of the bridge a person in NPS uniform was headed toward Geyser Hill, and I warned her of the bison.

In the mid afternoon I walked up on a gently steaming Uncertain, having missed it by about ten minutes. The wait for Grand was short and uneventful, less than an hour long. Once again we got a One Burst Eruption, but no activity from West Triplet either before or after.

Despite it being a bit breezy, it was warm and sunny and too nice to go inside, so went down basin to kill some time. Arrived at Riverside just before the eruption started. I don't remember Riverside starting this way, but it's been a few years since I've actually waited in the loop there. The back vent surge thickly several meters high, repeatedly for about twenty seconds before the eruption started throwing water onto the river.

Down at Fan & Mortar, bicycled up on High vent erupting to at least four meters, with Gold going strong next to it, and nothing else active. That activity continued intermittently for a number of minutes, until Angle started to join in. That's when the other two vents died down quite a bit, and shortly after, were left to themselves.

After intermittent evening showers, went out to Grand before sunset. About 18 minutes after a Turban eruption, West Triplet began to erupt. At that point, Grand didn't look good. But over the next twelve minutes, it came up and started to pour off water. Around the 32 minute mark, the overflow seemed to subside a bit, and at over 35 minutes, Turban began to erupt.

About 30 seconds in, Turban seemed to pick up in intensity, and in the dim light, it looked like Grand had risen back up and was having good waves. So no surprise when about 1-1/2 minutes after Turban started, Grand began another One Burst Eruption. It was another eruption that was long enough for there to be no doubt about there not being a second burst. Vent & Turban quickly restarted, and West Triplet was still in eruption as we left. From the bike rack I didn't see any activity from Rift.
