On Sunday, we signed up for a bus tour, always a good way to learn more about the area.

Our bus was a wonderful vintage vehicle, in one of my favorite colors. Obviously...both my shoes and backpack matched.

This may be one of my favorite pictures--the bus driver couldn't figure out what I was doing until I told him I was trying to get a picture of Old Faithful as seen through the windshield.

We chose the Firehole Basin tour.

Immediately before we were to get on the bus, the Beehive Geyser started erupting, named because the sound is like a huge swarm of bees, very loud bees. While it is not as predictable as Old Faithful, the water goes higher and the eruption is longer. It was quite spectacular.

Then off to Firehole Lake Drive.

 White Dome Geyser.

Firehole Canyon Drive.

 Firehole Falls.

On the way back, we stopped at Biscuit Basin--just a short stop as it finally started to rain.

The bacteria mats were fascinating--so much microscopic life enduring extreme temperatures.
