Latest Notes

Note IDStart Time (US/Mountain)End Time (US/Mountain)EntrantNote
22175 28 Jun 2022 @ 1510 --- aferrara Catch basin with eggs totally empty and dry
21318 16 May 2022 @ 1447 --- Brando One vigorous boil over the rim but sadly that was all
20749 22 Jan 2022 @ 1354 --- K.Cooper Just confirming and continuing what has been noted already. Small boiling inside of the cone but very little water outside. One of the side vents is active with some water coming out. Other side vents and the side pool have yellow and brown Cyanobacteria growing in and around them.
20673 11 Jan 2022 @ 1300 --- Graham No signs of recent eruptions. The runoff channel is snowed in, snow on boardwalk and the railing.
20231 30 Oct 2021 @ 1803 --- K.Cooper (Wc) Lots of stronger splashing well over the cone, a few of them made me go "wow."
19979 14 Oct 2021 @ 1400 --- Ben VL No excessive melted areas in the snow. BW still covered in snow too. Aurum looks about the same as it has most of the summer; mostly quiet, gentile splashing sometimes outside of the crater, and #3 bubbler oozing out water and bubbling gently. Not going to rule out the possibility of an eruption, but unfortunately the supporting evidence is a bit weak. See what the logger says.
18915 13 Aug 2021 @ 1230 --- Suzanne No obvious changes observed during and after the recent activity from Giantess. Two of the side sputs are constantly boiling and there is occasional boiling and splashing from the vent (but no cone-filling boils).
18024 22 Jun 2021 @ 1628 --- Graham Water a bit lower and less active.
17680 11 Jun 2021 @ 1020 --- TheHikingDude High water and periods of vigorous boiling. Tried to erupt a couple times before slowing to a halt.
17564 08 Jun 2021 @ 0633 --- Graham Splashing nicely in vent but water level is slightly lower than recent observations. May have gone overnight.
17136 19 May 2021 @ 1456 --- BobInSLC post eruptive, wet boardwalk
16879 17 Apr 2021 @ 1216 --- User34 Splashing confined to the cone, standing water level out of sight. Side vent 3 splashing but not pooling
16878 17 Apr 2021 @ 1148 --- User34 Splashing barely visible in main vent, side vent 3 gurgling but dry
16871 16 Apr 2021 @ 1624 --- User34 Post-eruptive
16200 20 Sep 2020 @ 0607 --- Graham Post eruptive deep buffing.
16187 19 Sep 2020 @ 0721 --- Graham In cone splashing, just reaching the rim. Not ready yet.
16178 18 Sep 2020 @ 1251 --- User34 Low splashing
16161 18 Sep 2020 @ 0653 --- Graham Post eruptive deep huffing.
16095 12 Sep 2020 @ 1835 --- Graham In cone splashing. Maybe erupted 2.5h ago?
16035 10 Sep 2020 @ 1320 --- Graham Huffing at depth. Erupted sometime.
16030 09 Sep 2020 @ 1849 --- William post eruptive, huffing at depth
15714 23 Aug 2020 @ 1730 23 Aug 2020 @ 2055 William Looked "ready" on arrival. No eruption witnessed during this time. At Aurum from 17:30-19:20, watching from the TB platform after that.
15662 20 Aug 2020 @ 1945 20 Aug 2020 @ 2200 William Aurum being Aurum... no eruption during this time.
15636 18 Aug 2020 @ 1618 --- Suzanne post eruptive
15584 15 Aug 2020 @ 1803 --- Suzanne post eruptive. probably went a half hour or more ago. boiling at depth, no surface water.
15128 30 Jul 2020 @ 1930 --- William post eruptive, huffing, runoff channels beginning to dry up from previous eruption.

14845 02 Jul 2020 @ 0544 --- Graham In cone boiling.

14719 24 Jun 2020 @ 0825 --- William post eruptive, huffing
14235 25 May 2020 @ 0838 --- Suzanne post eruptive
14180 04 May 2020 @ 1308 --- underarockphoto Both Aurum entries here only show steam on the static webcam. The weather this morning was highly conducive to steamy conditions. From my observations both entries are questionable. IMHO both should stay up as "wc ie ?" with a comment about it being on the static cam to at least leave a record that Aurum could have short intervals, or could totally fake you out.
14146 02 Mar 2020 @ 1400 --- JarnoO probable #2 in series, with 1356 ns as initial. Huffing @ 1407, may have been some water in there too (normal behavior post-eruption?).

14130 22 Feb 2020 @ 0822 --- Art Post eruptive huffing

14093 22 Jan 2020 @ 1202 --- Graham Splashing like it wants to erupt.
14090 22 Jan 2020 @ 0751 --- Graham Post eruptive steam huffing with occasional water droplets thrown out. erupted recently.

13960 21 Oct 2019 @ 1400 --- steve It looks like Aurum is ready.
13910 09 Oct 2019 @ 1355 09 Oct 2019 @ 1530 underarockphoto Cyclical boiling every few minutes. Satellite vent have minor eruptions to 1’ occasionally for a minute or so. Probably coincidental but Autum surges frequently coincided with Beach Spring
13909 09 Oct 2019 @ 1403 --- underarockphoto Boiling 1-2ft. Two side vents blipping.
13885 05 Oct 2019 @ 1238 --- Kitt B No Aurum yet. #3 is flooded with inch boil plus #5.
