When I woke up at 05:30, I wasn't surprised to see that there wasn't a report for Grand in the last few hours. I was surprised to get out there just after 06:00 to find a full pool and West Triplet erupting. On over 8-1\/4 hour interval, and Rift not to blame.<\/p>\n\n\n\n
Before that, from the bike rack at Castle, I saw Penta in a fairly strong steam-phase eruption. By the time I got there the water in the runoff had almost reached the boardwalk. Was still going strong, so I recorded a couple of minutes of video.<\/p>\n\n\n\n
West Triplet ended right after I arrived, so I expected the next Turban eruption would lead to Grand erupting too. Instead, got an hour's worth of Turban eruptions where the intervals were under 17 minutes. The One Burst Grand eruption finally started 66 seconds after Turban started.<\/p>\n\n\n\n

After about 25 minutes of this, we finally got an Uncertain eruption of sorts. The start was not abrupt, but consisted of the splashing getting stronger and taller with more overflow until finally the weak jetting was continuous. The height was less than two meters, but around normal length, dying down to heavy steam. At that point, Sawmill had one of its half-minute eruptions where there wasn't any overflow.<\/p>\n\n\n\n
Beehive was also having a long interval. I was there less than five minutes before water was visible in Beehive's Indicator. What little wind there was was blowing toward the river, so up by Plume we got a nice bright double half-rainbow.<\/p>\n\n\n\n
Decided it was too nice to stay indoors, so went to try our luck in the Lower Basin. Got to the entrance to Firehole Lake Drive to discover that Great Fountain was already in eruption, so no point in biking out there. Continued on to Fountain Paint Pots to see quiet Fountain Group. Even Clepsydra was quiet. Didn't stick around there either.<\/p>\n\n\n\n
Midday it was time for Rift. The Turban eruption interval after I arrived was at least 32 minutes long, so we also had a Turban Delay Interval to deal with. As it turned out, Rift ended first, after being active for almost two hours. Grand finally had the One Burst Eruption on the sixth Turban eruption interval, or one Turban interval after the end of Rift's eruption.<\/p>\n\n\n\n

Crystal was even having its pulsation heavy overflows. Bulger, however, was only having minor eruptions, so an eruption of Bulger's Hole seemed unlikely.<\/p>\n\n\n\n
By the time I arrived after sunset for the next Grand eruption, Belgian and Crystal had dropped considerably, from 15cm to 20cm. Sawmill was in eruption, but soon quit. Uncertain was showing water, acting like it was going to erupt, but then Sawmill had another eruption which lasted about a half hour. It wasn't until then that Uncertain finally erupted.<\/p>\n\n\n\n
The wait for Grand was only 1-1\/2 hours, a series of ordinary Turban eruptions and intervals. When Grand finally erupted, it was one of those starts where Turban erupts vigorously while Grand waits about a minute before starting. The One Burst Grand eruption by moonlight was quite nice, and it lasted eleven minutes.<\/p>\n\n\n\n
