There was some interesting stuff at Grotto and Giant (but no Giant).</DIV> <DIV> </DIV> <DIV>Grotto Fountain was at 0940 and seemed perfectly normal, except that it was accompanied by a full-force Startling and the Central Vents before Grotto started at 0943. Grotto turned off at 1115, so a duration of 1h 32m. South Grotto Fountain was occasionally active throughout Grotto's eruption, but then appeared to quit completely when Grotto shut off. That in itself seemed odd.</DIV> <DIV> </DIV> <DIV>Giant had a hot period at about 0900 -- I just missed it but found the platform steaming and Mastiff depth-charging at 0905. I had a near identical experience at 1002. But then, during the 1037 Oblong, I caught a hot period in progress at 1042. Yes, a 40+ minute hot period interval.</DIV> <DIV> </DIV> <DIV>This hot period was followed by exceptionally strong depth-charging in Mastiff which went on and on. It was at 1130 when I got a bit excited, for then I saw something I personally had not seen before: the depth-charging finally stopped as back Mastiff underwent what I must call an eruption -- for about 20 seconds it was jetting steadily 4 to 5 feet high with a very significant volume of water put onto the platform. Then the depth-charging began again, but this time from a water level visible while standing on the cage boardwalk. Yes. At 1144, very abruptly with a rapid rise in water level in Mastiff, a hot period started. At first, Mastiff was 3 to 4 feet high and wide, with a prodigious overflow. Feather and the Feather Satellite came on quickly. Rust was splashing, Cave was bubbling, Turtle was overflowing. Giant had vertical surging that sloshed onto the platform.</DIV> <DIV> </DIV> <DIV>Then somebody pulled the plug. After all that, the hot period duration was 3m 37s. Sheesh. (Well, yeah, it had been only about 3 1/2 days...)</DIV> <DIV> </DIV> <DIV>Daisy was at 0924 and 1149ie.</DIV> <DIV> </DIV> <DIV>Fan and Mortar's marker was in place at about 0930.</DIV> <DIV> </DIV> <DIV>Grand was at 2113E last night, then at 0716ie this morning. Today's electronic time, per Andrew, was 0710E, but the eruption did not end until 0725 (-2Q).</DIV> <DIV> </DIV> <DIV>At 0736, Tilt's Baby had a really fine, jetting eruption.</DIV> <DIV> </DIV> <DIV>I learned that on Saturday, at 1730vr, Black Diamond had a powerful eruption that visitors caught on camera. The report is that the images indicate an eruption height of 100 feet. I was also told that the eruption put a lot of debris onto the boardwalk, but this afternoon I could see no sign of that whatsoever.</DIV> <DIV> </DIV> <DIV>In the Lower Geyser Basin, on the drive in, I caught Gemini in full eruption at 0651. No indication of anything out of Crack, though, and no sign of overflow by Pebble.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV></FONT></BODY></HTML>
