Observations for 24 May — Giant Geyser


Graham Meech stayed out all night as Giant continued to have hourly hot periods during the night, none of them as strong as the one that occurred the previous night while I was making these postings.

The hot period at 05:22 had little Mastiff surging, and initially seemed to last 7m20s. Until Feather restarted and Giant almost immediately began strong vertical surging. Within three minutes, Giant began to erupt, at 05:32. (I was in my Lodge cabin getting ready to come out when Graham's call went out. When I heard him announce the restart, I knew I wouldn't be seeing this eruption start from up close. I was in front of the Lodge instead.)

The lighting was good, for at least my human eyes, and the wind direction such that the spray and steam was carried northward, making Giant's water column easily visible from a distance. It was too early for good backlighting.

As Giant died down, I rode my bike down to see Grand. Once again, it started as I was locking my bike at Castle. It was a 8m43s long single burst eruption. The only other thing of interest were the bison cow and calf who were, according to a visitor, standing in the runoff channel at the start, and finally realized that that was not a good place to be standing and took off running.

Other geysers of interest:

  • Oblong 05:27 ie
  • Daisy 05:07
  • Riverside 01:44, 08:23ie
  • Grotto 03:53
