Abyss Pool Hotter than in Over 30 Years

Over at West Thumb, Abyss Pool started heating up this summer. This pool has been quiet since its last active phase over 30 years ago when it erupted often from September 1991 through May 1992. At first, the eruptions came every few days or weeks but sped up to happen...

After Steamboat – a field journal entry

I knew it would happen at some point, and here it is. I'm stuck in a logjam of half-finished posts, notes that need typing up, and photos to process. Summer is here. In this post, you'll find the rest of my field journal entry for 19 July 2020. You can read the first...

Geyser Hill Observation Report for 26 Sept 2019

Geyser Hill Observation Report for 26 Sept 2019

The end of the summer season in Yellowstone was cut a bit short last year due to poor weather conditions. Because of this, I wasn’t able to get through all of the Upper Geyser Basin. However, I did do a thorough observational walk around Geyser Hill. In this post, I...

Survey Flight 2 Aug 2019

Recently I took another flight over Yellowstone to gather photos - not only for the photography side of my business, but also to write more Get to Know the Geysers posts. It's also an efficient way to keep tabs on the thermal features. This time I invited a couple of...

Steamboat throws a rock that splits the sign

Exciting things are happening at Steamboat Geyser. I headed in on the 12th and was lucky enough to catch that eruption and not be hit by the stray rock Steamboat tossed out. Then on the 15th, Steamboat erupted again for what looks like the shortest interval ever. I’ve...
