Observations for 2019 July 21


A dawn drive to Fountain resulted in getting as far as Silex before we were informed that it had erupted and quit already. Not observed, so it could've been over an hour earlier.

So it was back to the cabin and then out to see another One Burst Grand weruption, backlit by the rising sun.

From there it was down basin for the first time this trip. I passed by Solstice, still in eruption. Grotto was active, and I saw some splashing from South Grotto Fountain.

Waited through the better part of a cycle at Fan & Mortar. It was well defined. For example, when the vents shut down, they stayed off. None of that blipping from Angle Vent that never seems to stop. Bottom Vent started splashing heavily, and Lower Mortar was so full the water level could be seen at about the time a new cycle start was expected. When High and Gold did start,they were powerful. But during the quiet time, and during the Bottom splashing I saw nothing from Main Vent. It was cool, and there was very little steam.

By then it was time for Daisy, and to take a look at Splendid. The latter didn't look any different from the way it did back in May. A few minutes after the refill start there was boiling from Main Vent which ususally shifted to Side Boiler. The first few boils were about a meter high.

As I left, I check on Grotto, and it had quit while I was up at Daisy.

By the time I returned to the cabin, Beehive had still not erupted. The Indicator was behaving the same way as yesterday according to radio reports. When it finally came up, I almost didn't have time to get over there from the cabin. I left as it started, and was passing the Observation Point junction when Beehive started. Fortunately, the wind was blowing the spray parallel to the walkway, so no one got wet. I also noticed when I got close that the Close-to-Cone Indicator was bubble as the main Indicator was quitting. It continued during the rest of Beehive's eruption.

Went out to Grand a bit early to try to beat the crowds, so of course it not only has a delay, but take three Turban intervals to finally erupt. But I did get to see the activity I saw the other night in the daylight.

It started almost immediately after West Triplet started. I will have to check my old maps, but I think it is actually what I called "Sput D". It was to the left of Sputnik. Sput A was a small hole in the flat runoff channel area, and this is farther back. Percolator also started with West Triplet, and both stopped when West Triplet ended shortly after the One Burst Grand eruption.

Made another trip out to see what Morning might do. There was boiling at the back, but nothing came of it when Fountain started. There were also two periods of heavy boils from Morning's Thief, but again, that was all that happened. The eruption itself was shorter than the previous, only 32m10s this time.
