I will just send a quick email now before some of you head to the park this weekend.<o:p></o:p> <o:p> </o:p> Giant is interesting with the significant change in behavior. <o:p></o:p> Sunday May 11 – arrived in the evening<o:p></o:p> 2012 Bijou pause and water in Mastiff but nothing more and then I left.<o:p></o:p> <o:p> </o:p> Monday May 12 – Bijou was ‘normal’ when I got there at 0615 and Grotto was off. Bijou was having slowdowns and pauses 20-30 minutes apart just like the good old days.<o:p></o:p> 0927 pause and bathtub d=6<o:p></o:p> 1032 pause and Bijou on stronger after this<o:p></o:p> <o:p> </o:p> 1154 pause with water already in Mastiff<o:p></o:p> 1155 Giant Hot Period (GHP) d=3m10s SW vents on first, FS and Rust. The Bijou/Catfish (BC) vent was on briefly too. <o:p></o:p> Bijou roaring after the hot period and Mastiff started to depth charge heavily. This activity continued the Basin closed on Thursday! The depth charging is stronger than any I have seen before.<o:p></o:p> Sometimes Bijou would weaken a bit (but still be strong) and the BC vent would come back on and Mastiff would strengthen as if a hot period or pause had happened.<o:p></o:p> <o:p> </o:p> 1419 boil in Mastiff and water rising<o:p></o:p> 1420 GHP d=2 ½ Feather and SW, no Bijou pause<o:p></o:p> <o:p> </o:p> 1617 water in Mastiff<o:p></o:p> 1618 SW<o:p></o:p> 1619 GHP d=3m50s Feather and satellite, Cave to 2’, no Bijou pause – this was the longest hot period I saw.<o:p></o:p> SW vents off 2 minutes after Feather.<o:p></o:p> <o:p> </o:p> 1745 SW<o:p></o:p> 1746 GHP d=3m5s Feather and satellite, Cave boiled, no pause<o:p></o:p> <o:p> </o:p> 1751ie Grotto Fountain<o:p></o:p> 1805 Grotto d<18m<o:p></o:p> <o:p> </o:p> 1845 Bathtub, no pause<o:p></o:p> <o:p> </o:p> 1919ie Grotto Fountain<o:p></o:p> 1931ie Grotto<o:p></o:p> <o:p> </o:p> 1926 GHP d=3m40s, Feather and satellite, Cave 2’, no pause<o:p></o:p> <o:p> </o:p> Then things continued like this for the rest of the time I could get to Giant. I did see one pause on May 13th but Bijou paused after Mastiff rose. The activity seemed to decline slightly over the next couple of days though. Hot periods were weaker and Bijou was a little weaker although still roaring along.<o:p></o:p> <o:p> </o:p> So much energy there with Cave on short hot periods, Mastiff depth charging all the time – it often depth charged 6’ from the back vent as the water rose. I didn’t see Giant do any vertical surging in the afterplay although it did surge vertically occasionally during hot periods but nothing exciting as they were so short. <st1:country-region w:st="on"><st1:place w:st="on">India</st1:place></st1:country-region> never really got wet so there was very little overflow from Mastiff.<o:p></o:p> <o:p> </o:p> Other news:<o:p></o:p> <o:p> </o:p> Fountain Group – With the closings I got to see two Fountain eruptions on May 16, interval was 5h 51m, durations were 31 minutes. Fountain started just when I thought Spasm would start – when it was splashing up in the vent. Fountain beat Spasm and then flooded it before it could erupt. Jet had intervals of 7-12 minutes in the hour preceding Fountain for one eruption (I don’t know when Jet started for that eruption) and the initial Jet was 45 minutes before Fountain for the second eruption. I could not see any water in Fountain or Morning prior to the Fountain eruptions.<o:p></o:p> <o:p> </o:p> Mornings Thief did the biggest eruptions I have seen from it. Both times it had two big eruptions and they were 2 to 6 minutes after Fountain started.<o:p></o:p> <o:p> </o:p> Clepsydra paused after Fountain the one time I watched it, 6 minutes after Fountain finished (for 7 minutes) and then again 24 minutes after Fountain finished (for 5 minutes). That’s the first time I have seen two pauses although I usually leave after I see a single pause so maybe it happens quite often.<o:p></o:p> <o:p> </o:p> Norris – I went to see Forgotten Fumarole which was still active on the 13th and 14th. Intervals were 14 minutes and heights were 6’ or maybe a little higher. <o:p></o:p> <o:p> </o:p> West Thumb – Scott reported on Lakeshore which is quite entertaining although only 1-2’ high. It looks like Thumb Geyser has some water (at least I think it’s the Thumb Geyser hole). It was boiling a couple of feet. There is some water in Twin but the Surging Spring end has less water than last year. Occasional is active – it erupted once while we stopped there for lunch but I got no interval on it but it was >15minutes.<o:p></o:p> <o:p> </o:p> That’s about it for news from me. Have fun over Memorial Day weekend!<o:p></o:p> <o:p> </o:p> Graham.<o:p></o:p> </div> </body> </html>
