It was well after dawn before I got out to the Bijou Cage. As I arrived, Rocket had a major eruption. That was followed by two hours of not much happening. At one point there was a big Mastiff surge, and I thought I might be seeing a bit of water through all the steam, and Bijou seemed a bit noisier afterwards, but that was it.<\/p>\n\n\n\n
Went over to Grand. Today it was warmer and with a normal summer breeze, as opposed to the imitation Iceland winds of the past few days. There were just a series of Turban eruptions until we were approaching two hours, when West Triplet began to erupt. This eruption ended, and there wasn't a followup eruption of Grand. Instead, on the next Turban interval, we got a 30 minute Delay, with an explosive Grand start. The steam was such that I was unable to catch the start of Turban. When the burst ended, at first it looked like the pool had drained, but it came back and after nearly a minute long pause, we got a nice second burst, much taller than the first.<\/p>\n\n\n\n

After a minute, water could be seen in Mastiff, but while Bijou did slow down a bit, it never came close to stopping. The Southwest Vents sputtered much more than their usual spits, and when Mastiff drained, Bijou had a nice roar.<\/p>\n\n\n\n
With the long interval for Beehive, finally got over to Geyser Hill and make a Beehive video. Had to wait even longer, then we got a short Beehive's Indicator and a long Beehive eruption. The video was a success.<\/p>\n\n\n\n
It was still light when I went out for the nighttime Grand eruption. The conditions were warm for the time of night, with no wind. West Triplet was erupting, and 25 minutes later Rift started. Rift erupted for just over an hour, and when it quit, Grand was having a strong overflow. The crescent moon had just set. The Turban interval was longer than usual, but not enough to be considered a Delay. Turban started fairly explosively, and Grand followed within seconds.<\/p>\n\n\n\n
