Day 365, June 23

Here she is, Old Faithful! Now, that is a bunch of water being spewed! The geyser erupts every 60 - 90 minutes depending on the length of the last eruptions. If the prior eruption lasts less then 2 1/2 minutes, it is predicted that it will erupt again sooner. If there is a longer eruption, greater than 2 1/2 minutes, it will be close to the 90 minute mark. There are quite a few geysers in that area. We also saw a very neat display in the kids science area. The hot springs are different colors based on what bacteria grow there. The type of bacteria is dependent on the temperature of the spring. That is all very logical. The interesting point, for me anyway, was that the red bacteria grows at 110º, yellow at 120º, and blue at 198º. So the blue water is the hottest.
Here is one of the MANY buffulo. I wanted to reach out and groom them! Most of the bison were shedding in sheets of fur.
