Established in 1872 by President Ulysses S. Grant, Yellowstone National Park is one of my favorite roadtrip stops in recent memory. We spent only a day there, and I'd love to go back and spend much longer. It is a large National Park, with tons to see and do. Because it's basically located in a volcanic crater, geothermal features abound: bubbling mud pots and geysers and mineral-rich water in otherwordly colors. Everywhere I turned, I saw something that amazed me. And because we visited in October, we missed the hordes of summer tourists.
Thanks to my husband for the pictures!
Tomorrow is the last day of the A to Z Challenge! We're almost there!
