Yellowstone National Park Mammoth Springs, Grizzlies, and More
I'd heard of Mammoth Springs many times over the years, and seen some kind of boring photos, so I wasn't that excited about visiting, but I ended up being really impressed. As we did every morning, we were out of bed by 6:30 (which was 8:30 Eastern time), and ended up being the first among a few to arrive. It was the perfect time of day, as the springs face east, and the sun was just coming up.
In this section, a cascade of pools formed one after the other. The water trickles all the way down from one pool to another, depositing tiny amounts of minerals. This has been going on since before the Egyptians were building pyramids.
Another from the same area, at the top of the big face of the springs. This is the source for the water that trickles down the biggest face of Mammoth Springs.
Here is the largest face of the springs. The whole hill we've been walking on is the accumulation of thousands (millions?) of years of trace amounts of sediments in the spring water hardening into these shapes as it flows up from below, then downhill. A little like an extreme case of hard water in your home plumbing. I love the pure white, which is all stone - probably calcium.
Wildlife seems to be doing really well in Yellowstone National Park. Of all the animals we saw, the bison ignored people more than any other. They just didn't care. You've probably seen those films and photos where the bison just walk across the road right in front of cars. That did happen to us - a big traffic jam just because there was a herd split across both sides of the road, and every once in a while one or a few would decide they wanted to cross.
We got closer than the recommended distance on foot a couple of times. I swear it wasn't on purpose! They just pop up out of the woods, and there you are, too close together. This one was taken leaning out of the car window.This time, we were on foot and ended up closer than we should have been. We felt a little safer being up on a wooden walkway a foot off of the ground, but probably shouldn't have. That railing ends right in front of me, so there was nothing between us and him except one step up. We waited a few minutes for him to move a little further away, but instead he just came up until he was practically touching the walkway. So, we ended up turning around. Second time on the trip when we had to detour due to wildlife.
We saw black bears a few times on the trip. Twice, there were two black bears together in a single tree. The first time, the tree was right beside the road, and the rangers had set up orange cones directing all traffic into the other lane and were standing along the road every fifty feet waving people along telling us not to stop. So, no photos that time. The second, they were pretty far off the road, so we were able to stop and watch for a while. People said the mother likes to do this so any predators have to go through her to get to her cub.
Finally, near the end of the trip, we got to see grizzlies near the lake. Grizzlies are also known as brown bears. That's actually a more correct name for them, apparently. But grizzly sounds so much better! These were pretty far from the road, so we were always at a safe distance. And there were quite a few people stopped to watch. Three of them had tripods set up with very long lenses. If I lived in a place where wildlife was that plentiful, I'd definitely get one of those lenses! This first photo shows the mom and her cub together.
The cub.
The cub again.
That was pretty exciting. You never know if you'll get to see a grizzly, so we felt really lucky.
After four photo essays, we finally reached the end of this trip. Thanks for reading to the end. Hope you enjoyed!
The previous three posts cover the beautiful and amazing waterfalls, canyons, springs, geysers, and very close up moose we saw on the trip. Here are the links to those posts:

Geysers and Grand Canyon of Yellowstone National Park
I'd never heard of the Grand Canyon of Yellowstone until we got there. I knew there was a huge and amazing waterfall in the park, but didn't know an amazing bonus canyon came with it. The photo below shows the Lower Falls, which created the deeper part of the canyon. It's called the Lower Falls, because there is another waterfall only a mile or so upstream on the same river, called Upper Falls.
We spent a few days hiking both sides of the canyon, and visiting both falls. At the Upper Falls, they have a platform right next to the falls. There is a short, steep downhill hike, called Brink of Lower Falls, to the viewing platform. If you look at the upper right corner, you'll see a person looking out over the falls from the brink. This helps give a sense of scale to the scene.
Standing on the platform, it's a thrill to see the water rushing over the brink while feeling the rumbling sound in your chest. These next three photos are some of my favorites of the trip. I love how the individual drops of water catch the sun's rays in the closer part of the photo, the green tint to the water, and how it looks like an explosion of water in slow motion. I love the shapes formed by the water as it plummets hundreds of feet, and the way the sun illuminates the water from the inside. I these would look amazing printed six feet high, mounted side by side on a huge wall in a luxury hotel.
This is an early morning view looking downstream from Inspiration Point.
Here's another view of the Lower Falls from a trail along the south side of the canyon. The viewing platform for the Brink of Lower Falls is there. There is a softer type of rock underneath right where the falls starts, that's what created the falls. It started out flat, but the water wore away this softer rock much faster than the harder rock further upstream.
A view of more of the canyon. We spent every evening watching the sunset from somewhere along the north rim or the south rim. It's only a few minute drive to all the viewpoints along the canyon from Canyon Village.

We also spent time chasing geyser eruptions in Upper Geyser Basin. We were fortunate to be in the right place at the right time to see two geysers that don't erupt quite as often or as reliably as Old Faithful. Here's Beehive Geyser erupting. Some people stood right in the shadow of the spray and got soaking wet just for fun. The brilliant rainbow was a great surprise.
Same eruption of Beehive Geyser, without the people and walkway.
Here's Old Faithful erupting. They post a schedule in the visitor center, accurate to plus or minus about five minutes. There was a crowd of a few hundred waiting to see it. It lasts about a minute or so.
Some of the pools around the geysers and springs have thick mats of bacteria in amazingly vivid colors.
A great example of the colorful mats of thermophilic bacteria. This is the area surrounding Grand Geyser. Yes, the color is really like that in person.
Grand Geyser is the largest predictable geyser in the park, though the prediction time window is over two hours. You need to be patient or lucky to get to see it. We were a little of both. We decided to do the wonderful five mile hike around the area while waiting. On that five mile hike, we got to see the fantastic Morning Glory Spring. You can really see deep down into this one. The colors are thick mats of thermophilic bacteria. "Thermophilic" is just a generic term for "heat loving" bacteria that thrive in this extremely hot water all summer, and even during the incredibly cold Wyoming winters.
After the hike, we went back to the visitor center for lunch. The rangers stopped everyone on the trail due to an angry bison. We had to wait a while for him to calm down, then give him a wide berth. Finally Grand Geyser erupted. The eruption lasted a few minutes, and had a false start with a few smaller jets of water, and then a couple of false endings too, where it stopped, then shot way up again. That was a lot of fun.

Yellowstone National Park Springs and Waterfalls
Yellowstone is so large, it has parts in Idaho, Montana, and Wyoming. During our visit over this summer, we stayed at the Canyon Village area. We had to drive for over an hour just to get to the start of some of our hikes. Before visiting in person, I had the impression there were a few amazing springs and a few amazing geysers in the park, and that was it. I didn't realize that there are so many of both, spread out all over the park, that after a while, you start to lose track and they start to get mixed up in your mind. You might think to yourself, "Was that incredible blue spring the Silex Spring or the Sapphire Spring?" This one is definitely the Sapphire Spring, but don't worry, Silex Spring comes later.
The water is perfectly clear, so you can see deep down into the water and the mesmerizing color. Steam constantly wafts off of the water's surface, obscuring the view, and briefly warming the cold morning air as it drifts over you. I had to take one photo after another, trying to time the shot to match a second when it cleared just enough to get a good view of the water. This color is called cyan, and the color comes from bacteria called cyanobacteria. According to the park guides, different types of bacteria live in different temperatures of water.
