In 1872, Yellowstone became a National Park, in large part because of the amazing thermal features it contains. At that time, little was known about the behavior of geysers and hot springs and today more is known, but much more is still unknown. The information is scattered and everyone who visits has piece of that information. This is a place to learn, to share and gather together the scattered bits.


New boardwalk path at West Thumb

  When visiting West Thumb in May, part of the boardwalk along the south side of the area had been moved, and raised. I can’t say it was unexpected. In part, the area where the boardwalk used to go has a section that heated up slowly over the past 3 to 5...

Oh, Plume, how we miss you!

1 year 122 days and counting. Last seen on 26 January 2013. How easily we get used to amazing wonders when we see them all the time. Plume is one of those geysers we now miss. It’s still quiet. Well, it sizzles, and we can see water in the vents, but basically,...

New Webcam at Old Faithful

Love this new webcam! Great improvement over the older one. Thank you YNP, Canon and the Yellowstone Park Foundation for the improved Eyes on Yellowstone! Thanks so much to Eric Zimmerman for capturing this gorgeous sunset eruption. And here at Geyser Watch, you might...

Lakeshore Geyser 20 May 2014

  On Tuesday, Mike and I decided to head into Yellowstone to see what’s up (and down) at West Thumb Geyser Basin. Lots to report (and more to come), but the most interesting change was at Lakeshore Geyser where the larger pool was acting almost as a...

What’s up with the white stuff?

Last weekend while spending time on Geyser Hill, I noticed something odd. Quite a few features have turned white where they previously had fairly rich microbe growth in their overflow channels. I assumed it was just a heating up that killed off the microbes, but then...

First Visit of the Season

Just a heads up – this trip report somewhat overlaps the nature trip report posted on my other blog, Field Journaling. Trip Report from 21 April 2014 Yellowstone opened for the summer season on April 18 this year, and I told myself I’d wait for the east...

Yellowstone’s summer season begins today

Much of Yellowstone opens on this gray and wet day today. However, a report from geyser gazer, Will Boekel has let us know most of the Upper Geyser Basin boardwalks are closed due to bear activity – and carcasses in the area. He also reports they may try to open...

A whole lot of shaking going on

The past week or so has seen a huge increase in the worrying about Yellowstone. I’ve been busy getting settled here in Cody, and actually laughed out loud about the animals all running from the park. News of Yellowstone’s demise is greatly exaggerated. It...

Yellowstone Plowing Progress

Each Friday, the Park Service says they’ll be updating the progress on the plowing of the park. Here’s today’s update: We could tell yesterday they made it to Old Faithful because the seismograph there picks up the plowing activity – and shows...

GIANTESS is erupting!

The eruption started at 1455 today – and eruptions from Giantess can last a day to a day and a half including any concluding steam phase that might happen. The last eruption of Giantess was 13 Sept 2011. You can watch online here for just the streaming cam...

When Will the Supervolcano Blow?

Wondering if it’s safe to visit Yellowstone? Wondering if it will explode just like the movie? (You know movies are always 100% accurate – right?) Personally, I’m not worried. In fact, I plan to move with my husband to the east side of the volcano in...
