On Monday, we headed to Mammoth Hot Springs. Since it is a good distance from where we are staying in West Yellowstone, we had another early start.
That meant I got to enjoy another foggy morning! Who knew I would find fog so enthralling?



By the time we arrived in Mammoth Hot Springs, the geography had changed dramatically! It was no less beautiful, though.

Our first stop was the visitor center. This bull elk was hanging out on the lawn in front of the visitor center, bugling for his does.

The photo below shows Mammoth Hot Springs from a distance. All that white is siliceous sinter, otherwise known as geyserite. To me, it looks like a mound of dirty snow.

And this is what it looks like close up.

We started by driving through the Upper Terrace before parking the car and walking the boardwalk of the Lower Terrace.

The formation shown in the photo below is what makes Mammoth Hot Springs unique. These are called travertine terraces.

This is what they look like close up.

And from further away.

After leaving Mammoth Hot Springs
We did so much after leaving Mammoth Hot Springs that I’m going to post the photos with captions and leave it at that.











On our way back to the campground, we experienced our first true bison traffic jam. The park rangers eventually showed up to scare the bison off the road.

There’s always at least one idiot in the crowd…

It was a great day, at least for me.
By the time we arrived back at our campsite, Greg’s normal equanimity was experiencing some tatters around the edges. Between the stress of driving on winding narrow mountain roads, walking thousands of steps, and sightseeing, he was exhausted. (I think he has also had his fill of geysers, hot springs, and steam vents to last a lifetime.)
Tuesday will be a less intense day.
