Today we saw bison!
And we also saw a moose. We saw TRUMPETER SWANS! We heard that there were only a dozen pairs in the park. They were standing in front of their sign. If I were an animal I would stand in front of my sign too. If I were a weasel I would stand in front of the beaver sign and see how many people said, “Oh look there is a beaver.” Ahem, Ahem.
We saw Old Faithful. If you don’t like waiting a long time, go when there are a lot of people. That means it is about to explode. If you don’t like waiting, you can also go to Anemone. It explodes every 10 or so minutes.
Now near they have a visitor education center, you can go to the front desk and ask for a Young Scientist kit. They pay for it and then they will give you a bag with lots of stuff in it. Now, these are the ones I can name: a cool looking Taser-like thermometer, a stopwatch, a magnifying glass, rock samples, colored pencils, and a bacterial mat. By the way you have to get there early to get the bag. It is at the Old Faithful visitor center only.
If there is anything else when you go to Yellowstone, correct me in the comments.
