Observations for 2024 June 06


Just after dawn, Fan & Mortar behaved much like I saw the other day. Went down there just in case. Turns out that Bottom Vent did not erupt, and the activity of the Fan vents was better than what I had seen.

Spent half an hour in the Bijou Cage, just to see how things were. Bijou was strong and never stopped. Right after I left, I saw Grotto Fountain starting to erupt. Grotto had one of the stronger and taller starts I've seen in a while, in part because I was upwind over in the corner of the boardwalk.

By then it was time to go to Grand. Arrived to find West Triplet in eruption. As this was almost too early for Grand to erupt, we ended up having to wait the 2-1/2 hours for the next West Triplet eruption. It appears that right now Grand is being strongly influenced by West Triplet, and it's in the mode where there is a West Triplet Window. If Grand doesn't erupt during or immediately after West Triplet, it doesn't even try to erupt for the next couple of hours.

The eruption itself was another One Burst Grand eruption. While waiting, there was an eruption of Uncertain Geyser. I watched it from the benches, and it appeared to be quite tall.

Beehive erupted in the afternoon, and afterwards, saw a couple of new little sputs I haven't seen before. One is probably "Borah Peak Geyser" while the other is located near the location of Dragon Springs and hasn't been seen before. The latter only erupts to about a meter at a severe angle and lasts for maybe 20 seconds. It looks like something that is erupting from a drained pool.

Grand was set up for a sunset eruption, but by then the sky was completely overcast, and was just going to turn gray and then get dark. When I arrived, I saw that some bison had passed through the formations between the boardwalk and the geysers, and left a couple large deposits of well used plant-life. These became a source of humor, especially when the One Burst Grand eruption started and began to erode them. The large one created a discolored streak that reached the boardwalk.

The eruption itself was during the West Triplet window. When West Triplet started, there was a sort Turban eruption interval. The next interval was much longer. Grand's pool slowly filled and stayed full, looking like it might be a Turban Delay interval instead. Finally there was an explosive start to the eruption. West Triplet ended during Grand's eruption.
