Yellowstone: Some Initial Pictures

Unfortunately, my sister and I traded SD cards, and forgot to switch back, so I have only a handful of pictures from my recent vacation. Here are a few of the best:

Grand Prismatic Spring: the orange and brown colors come from different microbial mats, different kinds of which live at different temperatures. The turquoise  color at the center of the pool comes from particles suspended in the water. This shot came out a little artsy-er than intended.

As the water flows away from the pool, terraces form as minerals collect on little imperfections. These areas collect the microbes.

This is the water from the Grand Prismatic Spring and Excelsior Geyser into the Iron Spring Creek. You can really see how the microbial mats form in water flowing at just the right temperature and velocity.

This was a sweet restored car in West Yellowstone.
