Since it was a hot day, there was less steam hovering over the pools in Black Sand Basin.
Green Spring had some wispy, “fragrant” steam.
Mr. Gecko took this picture of Emerald Pool from his vantage point. He also took a couple of pictures of us, in which we were unprepared and looked it.
Spouter Geyser, which had been merrily burbling away when Mr. Gecko and I visited here, was quiet on this visit, but left behind some neat rock formations.
We stopped at Midway Geyser Basin, which was new for all of us. There was a line to get into the parking lot, but we managed to find a spot and took the boardwalk up to the thermal features.
Mr. Gecko took this picture of Opal Pool.
Grand Prismatic Spring is a huge hot spring, and it is amazing. Many of the pictures that are show of it are taken from the air, where you have the best vantage point. There are also “social trails” on the hill opposite the boardwalk to get a higher view, but those trails are illegal and damaging to the area there. Even from the side,though, the colors are startling and beautiful. It also shows up on satellite photos.
The steam here was pretty thick.
More microbe communities.
Excelsior Geyser was once one of the largest geysers in the world. It had a bit of an explosion, and now it is Excelsior Geyser Crater. The water here looks like it belongs in the tropics.Even though it no longer erupts 300 feet in the air, it still bubbles off and on.
We stopped at Artist Paint Pots on our drive, but more on that later…
Our last planned stop was at the Grand Canyon of the Yellowstone, where Upper and Lower Falls are located. We didn’t take any of the hikes around there, that will be another day, but we did stop at two of the overlooks to take pictures.The canyon walls have so many colors. There is a deep notch in the cliff beneath Lower Falls which allows more water to pour through there and makes a green stripe.
Our last unexpected stop was for a bison jam. I took over a hundred pictures of that, so it will get a separate post.
