Note IDStart Time (US/Mountain)End Time (US/Mountain)EntrantNote
17391 02 Jun 2021 @ 1632 --- JSJ Steam plume consistent with a small eruption, but no water seen over ridgeline from Pink Cone area.
17392 02 Jun 2021 @ 1455 --- JSJ Steam plume consistent with a small eruption, but no water seen over ridgeline from Pink Cone area.
17242 28 May 2021 @ 1825 28 May 2021 @ 2002 JSJ Box Spring very likely had other small eruptions during this time, in addition to the posted events. If water isn't visible over the ridgeline from my vantage point near Pink Cone, I don't call it an eruption, despite the presence of steam plumes. Such smaller eruptions are visible from the road near Bead Geyser.
