10404 24 Sep 2018 @ 1115 24 Sep 2018 @ 1220 Micah Kipple Nice overflows at 1115 and 1216. Between the overflows there was frequent blipping ranging from audible to 2-3" out of the cone. There appeared to be no correlation between Skinny's activity and the nearby intermittent springs.
10399 24 Sep 2018 @ 1115 --- Micah Kipple Nice push of overflow with water to the brim of the cone and bubbling.
9154 12 Jul 2018 @ 1311 12 Jul 2018 @ 1325 bhoppe Overflow at 1315. Due to extra sinter that had been carried into area in spring, overflow carries to southwest side of cone. In previous years, water flowed to the northeast of cone. Post-overflow bubbling began at 1319 but was very inconsistent.
4750 02 Aug 2017 @ 1533 02 Aug 2017 @ 1950 JSJ No eruptions. Intermittent spitting & very low to low splashing throughout observation period - sometimes wetting part of the cone, with some periods of quiet/calm. Overflow event (near start) at 1537 - done at ~1540. Overflow start at 1615 - moderately heavy; done at ~1618 to 1619. Overflow start at 1652 - short-lived and not heavy; already done by 1655. Overflow start at 1728 - moderately heavy at times; done at ~1731. Overflow start at 1803 - relatively short-lived; done at 1804 or 1805. Overflow start at 1852 - short-lived and relatively weak; done at 1853. Overflow start at 1943 - short-lived and relatively weak; done at 1945. Observed overflow event intervals today: 38m, 37m, 36m, 35m, 49m, 51m.
4536 25 Jul 2017 @ 1922 25 Jul 2017 @ 1959 JSJ In overflow push at 1922. Ditto 1941. Start of overflow push at 1959. ~18-19 minute intervals for overflow events.
4343 20 Jun 2017 @ 1020 20 Jun 2017 @ 1210 Tara Cycling with pushes at 1020, 1033 (very strong), 1105, 1133, and 1200. No eruption as of 1210.
4290 10 Jun 2017 @ 1328 10 Jun 2017 @ 1710 JSJ No eruption. Observed behaviors include: 1) very intermittent, very low spouts & blips & small splashes; 2) moderately frequent, low to very low spouts & blipping & small splashing; 3) light overflow events that filled the small proximal splash basin near vent; 4) relatively heavy overflow events involving water leaving the cone entirely and percolating into the proximal geyserite gravel. Observed overflow intervals (including "in overflow" events): 13m, 13m, 17m, 24m, 26m, 21m, 26m. Progressively heavier overflows as the afternoon progressed. Relentless cold wind made me bail.
4216 05 Jun 2017 @ 1248 05 Jun 2017 @ 1402 Tara Overflow cycles: 1248-1251, 1310-1312, 1329-1332, 1352-1359. Heavy overflows but not much splashing after.
3746 05 Oct 2016 @ 1320 05 Oct 2016 @ 1410 bhoppe Good overflows and splashing. Not as heavy as yesterday, but based on observed activity this morning, I do not think it erupted overnight.
3743 04 Oct 2016 @ 0945 04 Oct 2016 @ 1045 bhoppe Heavy splashing and overflows. I would expect an eruption some time today.
3708 24 Sep 2016 @ 0937 --- bhoppe Unsure if there was an overnight eruption. If it erupted overnight, it was not long after I left at 1945. Splashing within the cone and the catch basin was half full of water. If I had to guess, I THINK it erupted between 2000 and 2100.
3609 06 Sep 2016 @ 1900 06 Sep 2016 @ 1935 bhoppe Heavy overflows and string bubbling cycles. Would be unsurprised if it erupts overnight or morning tomorrow, but what do I know?
3612 06 Sep 2016 @ 0900 06 Sep 2016 @ 1420 Barbara Lasseter slight bubbling with water in the "cup" built to water splashing out of cone across the front and sides, then faded, quit, and the area dried
3391 01 Aug 2016 @ 1630 --- bhoppe Very dry and quiet. Probably erupted sometime in the morning hours.
3378 27 Jul 2016 @ 1200 27 Jul 2016 @ 1410 Tara Cycling, no eruption.
3375 26 Jul 2016 @ 1350 26 Jul 2016 @ 1545 bhoppe Good overflows and bubbling observed throughout the afternoon. No eruption as of 1545.
3329 19 Jul 2016 @ 2255 --- bhoppe No eruption yet
3309 17 Jul 2016 @ 1630 17 Jul 2016 @ 1800 bhoppe Good overflow and splashing cycles. No eruption as of 1800.
3298 12 Jul 2016 @ 1730 12 Jul 2016 @ 2100 bhoppe Great splashing following a push at 1840. No decent pushes or splashing when I left at 2100.
3206 04 Jul 2016 @ 1759 04 Jul 2016 @ 1930 bhoppe Saw 3 push cycles at 1759, 1835, 1921. First two cycles were very strong and very close to an eruption. 3rd push was weak. Will probably erupt in the evening or over night.
3138 26 Jun 2016 @ 1635 26 Jun 2016 @ 1730 bhoppe Periodic overflows that filled the catch basin on the immediate north side of the cone. Minimal splashing after overflows.
3110 21 Jun 2016 @ 1400 --- bhoppe Surrounding area bone dry - no visible water in vent. I'm guessing eruption probably within the past 6-8 hours.
3061 13 Jun 2016 @ 1623 --- bhoppe Just light steam, no water in any of the catch basins. I would guess it erupted sometime in the morning.
2949 02 Jun 2016 @ 1345 --- bhoppe Area dry with no overflows or splashing. Likely erupted overnight or this morning.
2863 20 May 2016 @ 2054 --- bhoppe No eruption as of 2053
2861 20 May 2016 @ 1715 20 May 2016 @ 1850 bhoppe Great water levels for most of the time observed. Pushes about every 15-20 minutes. I wouldn't be shocked if it goes soon, lightning pushed me out of the basin.
2853 18 May 2016 @ 1415 18 May 2016 @ 1555 Tara Cycling with overflow and a few splashes to 6-10 inches, no eruption.
2840 13 May 2016 @ 1410 13 May 2016 @ 1510 bhoppe Only one real push at 1419. A weak attempt at a push at 1454
2839 13 May 2016 @ 1135 13 May 2016 @ 1235 Tara Cyclic splashing as seen in prior years, no eruption.
2444 30 Sep 2015 @ 0830 30 Sep 2015 @ 0950 bhoppe Overflows at 0830, 0857, 0919. No overflow as of 0950. Post-overflow splashing was lethargic. "Monocle" (circular feature next to southeast corner of the observation platform) had overflowed twice after the 0919 Skinny overflow.
2333 12 Sep 2015 @ 1713 --- bhoppe Gurgling at depth. Area around crater bone dry. Probably erupted early afternoon
2302 08 Sep 2015 @ 1940 08 Sep 2015 @ 2006 Micah Kipple Could be heard splashing throughout this time. Intermittently the splashing would get strong enough to reach several inches over the Cone.
2301 08 Sep 2015 @ 1800 --- Micah Kipple Ovfl push, splashing.
2294 07 Sep 2015 @ 1855 07 Sep 2015 @ 2100 bhoppe Good gurgling/splashing in the cone. Heavy overflows throughout. Thought it was going to go at 2005. The next push at 2045 sounded good but was too dark to see. I won't be surprised if it goes overnight.
2292 07 Sep 2015 @ 1300 07 Sep 2015 @ 1500 bhoppe 1 heavy overflow at 1328. More burbling post-overflow than was seen yesterday. Didn't get to keep as close of an eye on it to time other overflows.
2250 03 Sep 2015 @ 1415 --- Tara Gurgling at depth. Erupted in the past couple of hours.
2233 01 Sep 2015 @ 1530 01 Sep 2015 @ 1600 bhoppe Had a really good overflow, but no bubbling/splashing during or after the overflow.
2193 26 Aug 2015 @ 1225 26 Aug 2015 @ 1400 Tara Not a lot of water in the system. Pushes were at 1239, 1258, 1341, and 1355 (weak). None of the pushes led to significant splashing when the water level dropped.
2139 15 Aug 2015 @ 1940 --- Tara A lot more water in system than 9 hours earlier. Strong pushes at 1942 and 2025, and a weaker one in between at 2008.
2126 15 Aug 2015 @ 0930 15 Aug 2015 @ 1100 Tara Pushes at 0942, 1006, 1017, 1037, and 1048. The last was the strongest with the water filling the cone. The splashing was pretty small, though, maybe 2-4 inches high.
2102 12 Aug 2015 @ 1215 12 Aug 2015 @ 1515 Tara Watched Skinny for 3 hours. There were a couple of good pushes with overflow and small splashes, but no eruption.
