Unusual Activity on Geyser Hill (Part 2)

I recently wrote about my observations of the Geyser Hill area before the September 2018 energy surge. It’s taken a bit to get the observations and photos together to make a better comparison. I’ve also spent time processing photos from the past to just satisfy my...

Unusual Activity on Geyser Hill (Part 1)

It’s often in the fall that we see some interesting changes happen in the geyser basins. This September saw a rather large change on Geyser Hill (near Old Faithful) that’s resulted in some unprecedented behavior (as far as records show). In this post I’ll do my best...

Is Steamboat Geyser entering an active phase? That’s the question many are asking and in this in-depth post, we’ll take a closer look at Steamboat Geyser’s past behavior and learn from those who documented the behavior when it was regularly active. 35 Days 11 hours 9...

Sawmill Group: Where we last left them in 2017

Sawmill Group: Where we last left them in 2017

One group of geysers and hot springs I’m curious about any changes seen is the Sawmill Group, over near Grand Geyser a little way beyond Old Faithful. The group that “normally” has either Sawmill Geyser in charge of the eruptions or Penta and Churn Geysers in charge...
