Bluebell Pool and Seismograph Pool are right next to each other and are notable for their temperature difference. Typically Bluebell is blue (of course) and Seismograph is green/yellow/orange. In 2010, both Bluebell and Seismograph were blue.
In 2006, Lakeside Spring was a hot, blue pool. By 2010, it was a green pool with a distinct orange border.
I seem to have only two pictures of this feature, which can’t be right. Even if there are more and I can’t find them, it certainly doesn’t seem to inspire many photos.
It varies from year to year and season to season whether Big Cone is above or below the water. I have two pictures from July in different years. One is above the water and one is not.
This is the pool next to Big Cone. Somehow I just ignored it for years and only had one closeup. Then I realized that this was a different feature from Fishing Cone, Big Cone, and Lakeshore Geyser.
Highly variable, I’ve seen these watery and dried up.
Lakeshore Geyser is sometimes underwater and sometimes not. I picked this photo for the clear greenish water that has almost a stained glass or mosaic look.
My photo of this bubbler was published in the Sput in 2009, the bimontly publication of the GOSA, the Geyser Observation and Study Association (http://geyserstudy.org). In 2009, this bubbler on the side of Fishing Cone was active and had a bacterial mat. A year later, Fishing Cone was underwater.
I guess when you have to come up with 365, you end up with some like these. I think I need to get to some more backcountry basins.
Yes, we are up to Z in West Thumb features. I’ll leave it as an exercise to the reader to figure out where this one is. Hint – you can see the lake, the boardwalk, and a bit of Blue Funnel Spring.
