Left a half hour later today so we would not be driving to Norris in the dark. Arrived in the parking lot there to discover that, not surprisingly, there were already quite a few gazer vehicles there.
The day was cloudy and didn't warm up as fast as yesterday. So by 10:15, I had not shed any coats, and didn't really feel the need to. That was when the fun began.
There had been some gazers at the platform during the night, and they reported a series of strong minor play around 05:00 or so. So it wasn't too surprising that New Crater wasn't showing much activity for the first few hours. That changed shortly after 10:15, when it began having a quick series of strong minors. I hadn't set up my tripod, and half-way through trying to do that, realized I should just forget it and start recording.
So I caught another minor, and it dying down. Almost immediately, another one started. Then it became obvious that the North Vent was building and climbing, and we were getting our eruption. The water briefly hit the platform, but that was the only time during the eruption that there was any threat of getting wet.
Since it was early, I decided that it was the time to try for a height measurement. I'd already determined that the bench on the boardwalk leading to the platforms would be a good place to work from, so I quickly moved there. Unfortunately, the sun and the top of the North Vent water column were close together, making it hard to get a reading at first until I could work out a way to shade the clinometer. About 4 minutes into the eruption, at 130 meters, I got a reading of 80%. That works out to 104meters, or about 340 feet. I haven't yet determined the altitude difference between that location and the vent, and need to confirm the distance, but that value sounds about right.
After that, I took advantage of the lack of crowds to head down to the runoff. The amount of water coming down both of them was impressive, The main one had obviously flowed over the walkway for a while, but was back below the bridge when I got there.
I returned to the platform, and now things were getting crowded. It gets really annoying when tourists who spent no time waiting try to elbow their way to the railing in order to get their precious selfies. I wasn't the only gazer who wasn't helpful in their trying to acheive that goal.
The North Vent column was reddish brown again, while the South was a clean white. Because of the wind direction, there was considerable wash from the hillside behind the North Vent, and I am sure that's where the color comes from. The water phase lasted about 43m, and it wasn't until then that the North Vent finally lost the brownish color.
There was only a light coating of the parking area, and despite the mid-day gridlock, were able to get out of there reasonably fast.
On the drive back, in the Fountain Flats we got to see the first bison herd of the autumn make its appearance. He had to see it, because the traffic was backed up to the Nez Perce bridge. Must have been about 100 of them out there.
No Giant eruption while we were gone, was a bit of a relief, but would have accepted it, considering. Got back in time for a weak, Feather-only Giant Hot Period. Figured that meant there was time to see Grand. Which had its first long (7 hours) interval in quite a while. So a bunch of people all abandoned Grand when a Bijou pause turned into a Feather eruption.
That one was strong enough to have a restart, but no eruption. Not trusting it, I came out at night at the four hour mark, expecting to see that I just missed another, but instead waited until almost midnight for another, similar hot period. Things there are starting to look like last interval, where we had several days of medium to strong hot periods every 6 hours or so.
