Yesterday was just a preview, but today was our first full day visiting world-famous Yellowstone. The Yellowstone Caledra, located in the center of this first National Park, is actually an active volcano. The largest supervolcano on North America, this caldera erupted several times in the last two million years. Today it hosts half of the world's geysers and hydrothermal features. After picking up Junior Ranger books for the children, we started our visit with a drive through Firehole Canyon taking many pictures along the way.

Applying what I learned from driving a trip on one charge, I experimented online with all kinds of driving routes in Yellowstone and quickly determined that there was no plausible way I would run out of charge before we returned. It turns out the tourists would slow us down so much we ran out of time long before we could possibly run out of range.

Firehole Canyon Drive is one of many parts of Yellowstone meant to be toured from the car. This Tesla gave us the perfect way to do that, driving in silence to cause as little disturbance as possible to the environment, the wildlife, and other tourists.

We then drove through Lower Geyser Basin, visiting Firehole Spring, the Great Fountain Geyser, and White Dome Geyser (see top picture).

Now that it was lunchtime, we continued to the Upper Geyser Basin to have lunch and attend a Ranger talk. We returned to Old Faithful to see the geyser erupt a second time. Then we returned north to Midway Geyser Basin to see the Excelsior Geyser Crater, the Grand Prismatic Spring, and Turquoise Pool.
