10272 17 Sep 2018 @ 1702 17 Sep 2018 @ 1728 ThomasR Morning had frequent small splashes (approx. 4 Inches) prior to the Fountain eruption and boiled up when Fountain started at 1728, but did not erupt.
10195 14 Sep 2018 @ 1205 --- Suzanne no water visible
10165 12 Sep 2018 @ 1011 12 Sep 2018 @ 1451 Brian Arrived at Fountain at 1011, water visible in Morning and Fountain. Fountain pool rose 3” around SFP at 1018. Morning pool dropped at 1039, but recovered by 1048, while Fountain also got somewhat higher. Morning North edge boil started around 1055, got gradually stronger and started to include center pool convection. Convection continued while pool continued rise right up until Fountain start at 1408. Morning had a boil over vent at Fountain start, then lost view of activity due to steam. Strong SW wind was blowing water from Fountain directly into the Morning pool After end of Fountain, Morning pool continued at high level for a few minutes until draining out of view by 1451.
10161 12 Sep 2018 @ 0730 --- Suzanne no water visible
10162 11 Sep 2018 @ 1700 11 Sep 2018 @ 1717 Polly Water in Morning was just visible upon arrival at about 1230. From then on, Morning rose slowly but mostly steadily. As it got close to time for Fountain, Morning rose a bit more quickly. It became steamy and had continuous boiling along the back wall. I saw one brief small boil in the middle. (It was a windy afternoon.)
10150 11 Sep 2018 @ 1000 --- Maureen Run off channels on back side of Morning were wet.
10137 10 Sep 2018 @ 0859 10 Sep 2018 @ 1328 Brian Water first became visible in Fountain and in Morning at 0935. Fountain rose a few inches with start of 2nd SFP at 1101, and held steady at that level until the usual rise right before eruption. The Morning pool was more variable, noticeably dropping around 1138, only to rise again and begin boiling slightly at the North edge. Some convection and a few lazy bubbles observed in center of pool periodically over the next 2 hours. Large Morning boil at start of Fountain at 1327, proceeded quickly to bursting and eruption.
10110 08 Sep 2018 @ 1412 --- bbev No water visable, empty.
10086 07 Sep 2018 @ 0740 --- Maureen Run off channels on back side of Morning wet. From last night’s eruption or another?
9850 24 Aug 2018 @ 0615 24 Aug 2018 @ 0701 JimS No water visible, lightly steaming.
9846 23 Aug 2018 @ 0800 23 Aug 2018 @ 1310 Micah Kipple No Morning yet. Pool level gradually filled throughout the morning and by 1310 had a steady boil in the pool.
9842 23 Aug 2018 @ 0627 --- JimS Empty at 0627 with very light steam.
3736 01 Oct 2016 @ 1545 --- Tara Water level very high to match Fountain, about 18 inches below rim. No boiling seen, no water visible in or around Morning's Thief.
725 22 Dec 2012 @ 0000 22 Dec 2012 @ 2359 Micah Kipple Runoff Channels were melted, Sinter Platform was washed, and Fountain was spitting out a \"tremendous\" amount of Rock.
385 13 Aug 2012 @ 0000 13 Aug 2012 @ 1200 Maureen Signs lead to a possible Morning eruption early this morning. I wrote a post on the list serv about it.
378 04 Aug 2012 @ 0700 --- Maureen when I walked out at 0700, the stairs going down to Fountain were very wet. The lower boardwalk was dry, as was the overlook, leading me to think maybe a big burst lay down there...in the evening it was where I was watching Fountain, and the stairs were DRY when I left the area after the 2131 eruption. No rain overnight. Twig was also dry along with Fountain.

797 18 Jun 2012 @ 0800 18 Jun 2012 @ 1931 Tara Morning likely erupted mid-morning on June 18. Morning\'s Thief erupted only after the 1931 Fountain had started and Twig was early during that Fountain as well.
