Turns out Grand erupted only an hour after we left, so needed to get back out a bit earlier than I'd expected. Still ended up waiting two hours of ordinary Turban eruption intervals. During that time Castle had a short, minor eruption, the Grand filled and erupted without a Turban Delay Interval. The One Burst Eruption lasted less than ten minutes, and showed no signs of trying for a second burst. West Triplet started in the middle of the Grand eruption, but I didn't stick around to get a duration.<\/p>\n\n\n\n

West Triplet started to erupt before I saw the first Turban eruption for this wait, so I figured it might be a while before the Grand eruption. Turned out to be less than an hour and a half, and the end of that consisted of a Turban Delay Interval lasting over 30 minutes. This time the One Burst Eruption lasted well over eleven minutes, with the last four in Big Sawmill mode, acting like it was about to stop, but never quit succeeding.<\/p>\n\n\n\n

After dinner, Beehive's Indicator was called on the radio. It being late evening, with the sun low and still windy, there was a full arc double rainbow visible from the western side. At one point I had to deploy the umbrella, and almost got a full circle rainbow.<\/p>\n\n\n\n
According to the NPS radio traffic, around sunset there was a bear hanging around near Castle. A hazing round was deployed to move it back into the trees.<\/p>\n\n\n\n
Got out to Grand early. After about five minutes, got a Turban eruption that lasted over five minutes. The next Turban eruption had no overflow preceding it, so I assumed that there had been a Turban Delay interval and I was in for a long wait.<\/p>\n\n\n\n
Instead, Grand was heavily overflowing and there was indications that I was about to get another Delay Interval when Grand explosively started erupting. Turban took nearly a minute to start, and this was another case where Vent took nearly four minutes. The One Burst Eruption lasted just long enough to ensure there wasn't a second burst.<\/p>\n\n\n\n
