A new geothermal feature every day in 2011.

Opalescent Pool

I used this photo as the album cover for one of my Yellowstone albums and that is why I chose it for the final photo. How many Yellowstone photo projects do I have?

  • Several albums.
  • Rolodex with one image per rolodex card.
  • Trail guide, first edition.
  • Trail guide, second edition, two volumes.
  • Trail guide, third edition, two volumes (160 pages).
  • Blog.
  • Thermal feature iBook.

Norris Back Basin Feature K

For such a colorless, small feature, I find this one fascinating and have several pictures. The water is crystal clear and the little terrace is smooth and white. The water doesn’t so much splash as burble.

Mud Volcano

The photo is a little blurry, but at least it has some life. Otherwise, the photos of Mud Volcano look like mud puddles.


This non-descript but bubbling pool is in the Terrace Spring basin.

Norris Back Basin Feature J

This feature is out in the field near Porkchop Geyser. It has two vents and is a perpetual spouter.

Seismograph Pool

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.

Chocolate Pots

This isn’t the best picture. It was late in the day and I propped the camera on the rock wall (instead of getting the tripod out) to make up for the long exposure. I almost focused on the right spot.

Minute Geyser

I don’t have any pictures of Minute Geyser not erupting, so it must be a perpetual spouter, or at least nearly so.

Diadem Spring

I am not sure how Diadem Spring rated having a name. The interesting thing about Diadem Spring is that it looks completely different in photos depending on where you stand.

Dragon’s Mouth Spring

I like to take pictures of Dragon’s Mouth Spring, but it is not easy. The pool boils at the opening in the hillside, putting out a steady steam cloud. If it doesn’t obscure or fade the colors, it messes up the exposure settings. So this one is another of my drive-by features. I drive by, hop out, take a few pictures and then check them out when I get home.
