Seen from Wave-Beauty, Mastiff was to 2 feet, huge amount of steam from the platform. Bijou was probably on throughout -- at least it was on well before Mastiff dropped (apparently) at 0828. Minutes later, on site, I found that India had been about 3/4 covered. Giant was surging hugely, frequently vertically throwing water over the back of the cone. One surge I'm sure reached 10 feet above the top of the cone. Feather was splashing, Slit bubbling, SW ( ! ) oveflowing with no jetting. This action gradually died down.</DIV> <DIV> </DIV> <DIV>0944, water rising in Mastiff, Bijou fully on. Water rose in M to about 3 inches below overflow and sat there. SW Vents came on. Interesting -- Bijou shut off at the "same" instant that Mastiff dropped; came back on after about 30 seconds. Bathtub.</DIV> <DIV> </DIV> <DIV>1047, water rising in Mastiff, Bijou fully on.</DIV> <DIV>1049 GHP Feather and SW only, overall weak, d = 2m 03s. Bijou stayed on until about 1 minute after Feather came on.</DIV> <DIV> </DIV> <DIV>1155, water rising in Mastiff, Bijou fully on.</DIV> <DIV>1157 GHP Feather and SW only but with some pretty decent Mastiff boils so overall better than 1049. D = 2m 19s. Bijou never completely shut off during this hot period.</DIV> <DIV> </DIV> <DIV>1303 Oblong</DIV> <DIV> </DIV> <DIV>1306 Grotto Fountain, (d < 11 min), Grotto 1309</DIV> <DIV> </DIV> <DIV>1322, water rising in Mastiff, Bijou powerful</DIV> <DIV>1324:44 GHP, Mastiff boiling 2-3 feet in both vents but only light overflow. Feather and SW, then Satellite. With Satellite was spurting in Rust and bubbling in Cave.</DIV> <DIV>1326:30 Cave is suddenly jetting 1 to 2 feet, then 3, then bursting 3 to 4 feet. Rust is jetting to 1 foot. Feather is cone high, Mastiff boiling, Bijou (never off) roaring. Note: no water visible in Slit, Turtle, Postholes.</DIV> <DIV>1328:28 VERY suddenly, F, FS, R, C all off as Mastiff dropped like a plug was pulled. Bijou roaring.</DIV> <DIV>Crap. Total duration 3m 44s.</DIV> <DIV> </DIV> <DIV>1434, water rising in Mastiff, Bijou on</DIV> <DIV>1437 GHP (disappointing), d = 2m 09s. Feather and SW only, Bijou never turned off.</DIV> <DIV> </DIV> <DIV>1537, water rising in Mastiff, Bijou weakening and then, would you believe, off.</DIV> <DIV>1539, GHP really weak, D = 1m 49s with Feather and SW only.</DIV> <DIV> </DIV> <DIV>NOTE: Early (roughly 0830 to 1000) the North and East (NOT South Purple Pools were overflowing heavily, steaming streams to the river with enough volume that the turbulence and bubbling at the river was visible from the platform with naked eye. This overflow gradually declined and appeared to have completely quit by about 1300.</DIV> <DIV> </DIV> <DIV>Mastiff was in constant depth charging between hot periods.</DIV> <DIV> </DIV> <DIV>On reflection, I think Giant tried to erupt on the 0824ie hot period. There clearly was a huge amount of energy there, as there were over-the-side jets throughout the day, vertical surging during even the bathtub, and etc. However, that last hot period was the first one that acted "normal." And so we left. Sign logs rolled tomorrow? No surprise.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV></FONT><BR><BR><BR><DIV><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">Wondering what's for Dinner Tonight? <A title="http://food.aol.com/dinner-tonight?NCID=aolfod00030000000001" href="http://food.aol.com/dinner-tonight?NCID=aolfod00030000000001" target="_blank">Get new twists on family favorites at AOL Food</A>.</FONT></DIV></BODY></HTML>
