Latest Notes

Note IDStart Time (US/Mountain)End Time (US/Mountain)EntrantNote
9896 27 Aug 2018 @ 0704 --- STS Is there an eruption missing between 22:32 and 01:24?
9554 08 Aug 2018 @ 1947 --- c.barwin This eruption was featured live on the final evening of National Geographic's Live show.
9536 08 Aug 2018 @ 0705 --- DGInc ~30s sustained pre-eruption preplay.
9498 06 Aug 2018 @ 1939 --- c.barwin This eruption was covered on the 8/6/18 National Geographic's Yellowstone Live show.
9225 16 Jul 2018 @ 2100 --- STS Saw people leaving the area starting at 20:56 so an eruption probably between 20:50 - 20:55
9145 11 Jul 2018 @ 2154 --- STS Given the 3 hour interval between 18:29 and 21:30, it’s safe to assume there was an eruption sometime around 20:00.
9087 09 Jul 2018 @ 2014 --- STS NPS lists new prediction of 9:02 ± 10 minutes at about 7:35. OF probably erupted sometime around then.
8712 16 Jun 2018 @ 0912 --- DGInc Large, sustained preplay made me think OF was going to start. It didn't.
7964 02 Apr 2018 @ 1140 --- Kevin L Snow was so heavy OF area was totally a whiteout on both streaming and static cam
7955 08 Mar 2018 @ 0643 --- DaveM This eruption was a long duration 3m10s
7817 09 Nov 2017 @ 0632 --- DGInc Appears to be post-eruptive. Runoff channels steamy. Temperature as of writing 23°F.
7798 30 Oct 2017 @ 1017 30 Oct 2017 @ 1018 DGInc Strong preplay, which could've resulted in an eruption.
7283 25 Sep 2017 @ 0924 --- Kitt B preplay, so previous eruption was a short
6996 23 Sep 2017 @ 0632 --- DGInc ~45s strong preplay which usually results in an eruption. No eruption followed.
5071 19 Aug 2017 @ 1817 --- Graham Really big and long preplay that would normally start the eruption.
4503 19 Jul 2017 @ 1500 --- SteveO VC in now predicting Old Faithful 98 minutes + or - 10 minutes
4120 23 May 2017 @ 0513 --- DGInc Was pre-eruptive spouting. Likely went before 0530.
3270 09 Jul 2016 @ 0246 --- DGInc Looked like it was in a post-eruptive phase. Definitely went during nightly reset.
3220 06 Jul 2016 @ 0207 --- smousley This is my first time on the site. I live in Dubai, hence the odd time of this note. I was looking at the ABC News Live cam, which is not so live, and came here to find out when the next eruption of OF might be. Then is seem strange that there is no reported eruption for over 4 hours. Is it because no one reported one?
3141 27 Jun 2016 @ 0216 --- DGInc May have erupted during early (0216-0225) nightly reset of the webcam. A lot of pre-eruptive spouting just before the interuption.
2935 01 Jun 2016 @ 2017 --- MikeG Forgot to write down eruption time. It might have been 20:17, and short duration.
315 22 Jun 2012 @ 0546 22 Jun 2012 @ 0552 Loisb I have OF starting at 0546 per the UB cam and it was a long. I also have Lion starting at 0552 which would make it an initial
111 17 Feb 2012 @ 1011 --- BB OF was 10:11 ie wc (time stamp UGB cam)
88 24 Jan 2012 @ 1250 --- ofcarolyn Park employees are downloading Old Faithful\'s temperature logger near 12:50 p.m. today.
727 19 Jan 2012 @ 1200 19 Jan 2012 @ 2359 WillBoekel Electronic temperature trace for the afternoon/evening has no spikes. Probably caused by an ice dam diverting the runoff.
