Observations for 2025 August 25


Went out to Grand before midnight expecting to see evidence that Rift had erupted. As I approached Crystal, I could hear Slurp slurping away. Which happens when Crystal is full and flowing into Slurp. Belgian was also quite high, and West Triplet was empty and dry.

Had to wait about 1-1/2 hours of non-descript Turban eruptions before a Turban eruption that was noticeably stronger and louder. This activity continued on for nearly 1-1/2 minutes before the Grand eruption finally started.

It was a long burst, and easily been a One Burst Eruption, but after almost a minute, got a nice second burst. If this burst had lasted a bit longer, the eruption would've earned it's "*".

Went back out in the cool morning about 7-1/2 hours later. Once again there was a series of uninspired Turban eruptions. Then we had a short Turban eruption interval, followed by a second one where Grand started having a full pool with strong waves around the 13 minute mark. It took Grand over two minutes of strong pulsations and heavy upwelling before it finally had the first boop, nd even then took a few seconds to get started.

Again, that burst ended with a duration that could have easily been a One Burst Eruption, but almost immediately Grand's vent refilled, and again it sloshed around for what seemed like a long time before the second burst started. It was dead calm, and the water column was extremely high.

During the eruption, West Triplet started to erupt. I figured that this would probably be the eruption that triggered Rift to erupt, so stuck around to at least get the length of the West Triplet eruption.

It took Rift 45 minutes from the start of West Triplet to finally make an appearance. The West Triplet eruption itself lasted about 1h13m, which is one of the longer eruptions that I can remember.

The walkway is blocked off just north of Turban again for the boardwalk construction, so there were a lot of people going as far as Grand's sign and heading back. At one point when the area had emptied out, I noticed a woman hanging around the northern runoff channel. With no one around, she got out a spoon and her phone/camera, dipped the spoon into the runoff and then did a selfie recording while sipping from the spoon. She repeated this action from the West Triplet runoff channel. As she passed me at Rift, I casually mentioned that randomly sampling thermal runoff was not the best thing to be doing, as some waters can be pretty nasty. She shrugged it off with a no-spika-da-Englis attitude. I'll let someone else do the YouTube, Instagram, or TikTok video searches.

Went on down to confirm that ignoring Fan & Mortar this trip has been the right decision. Spent an hour there and saw garbage mode. On the way back, I noticed that Rift was quiet 1h45m after it had started.

Went out for another Grand 1st overflow time, expecting to wait a while. Once again, Crystal and Belgian and high, with the first almost to overflow. The first overflow took only 4h31m, but came during another Turban Delay interval. It's almost like Rift had no effect on Grand this time.

The next Grand eruption tended to support that hypothesis. Was originally planning to head out later, but decided to come out instead at around the 7h15m mark. Waited three normal Turban eruption intervals and then Grand had an early fill with heavy waves and finally the One Burst Grand eruption, which lasted one second over ten minutes. It was followed by an eruption of West Triplet, which seems like a quick recovery for it, too.
