Yellowstone geyser area has many interesting features which attract thousands of visitors. Fortunately there are some that are off the beaten path and less crowded. The colors in the hot springs are beautiful.
Great Fountain Geyser goes off every 9 to 16 hours, making it a hard one to see. I didn’t catch it during the day but one night it was supposed to go off at between 8 pm and 1 am so I arrived plenty early. Needless to say it took its time and erupted at about 9:30 pm, in total darkness. A factor hard to figure into it was the amount of steam produced by the hot water and cold air. That made it very hard to photograph any water being sent up. The eruption lasts a pretty long time and by the end of it there were some stars visible so I capture a bit of steam lit by a light I had and the Big Dipper.
One of my favorite geysers is White Dome Geyser since it goes of frequently (every 20-30 minutes) and is usually pretty free of spectators. The first evening I was at Madison campground I went over and got a nice sunset image of it.
Then I went back that night to see if I could get the Milky Way above it. I did, though there were clouds and smoke so the images weren’t as clear as in the past. The difference this year was the forest fires in the park, they reflected on the clouds and made the images very unique.
