Went out to the Cage for an hour-and-a-half at dawn. Walked up on the start of Grotto, then saw nothing much, other than some well spaced small Mastiff surges and one episode of Catfish splashing. Bijou never paused, although it seemed like it might have been trying to roar when I saw Catfish.<\/p>\n\n\n\n
After breakfast, went over to Grand, where Rift was once again in eruption. It must have been near start, as West Triplet was also erupting. Rift finally quit after an hour-and-a-half. Grand finally had the One Burst Eruption following a minimal Turban Delay Interval.<\/p>\n\n\n\n

Waited for two hours, and during that time Bijou never stopped. Once again, there were some well spaced Mastiff surges, and Catfish splashed a couple of times. Bijou finally paused about two hours after I had left.<\/p>\n\n\n\n
(On the way to the Cage, at the bend in the biketrail near the river I encountered the better part of a flag-tour well off trail and all down by the river.)<\/p>\n\n\n\n
Went out to the evening Grand with the expectation of seeing it in the dark. Instead, Grand actually cooperated, and the One Burst Eruption began about five minutes before sunset. If there had been a second burst, it would have only been illuminated at the top. West Triplet began erupting moments before Grand, but this eruption lasted only about 1-1\/2 minutes. A second West Triplet eruption began during the Grand eruption. Did not wait to see if it resulted in a Rift eruption.<\/p>\n\n\n\n
