Steamboat Geyser, Yellowstone - Huge Eruption!

While staying in Yellowstone National Park, we wanted to buy a National Park passport book. We were told at our lodge that there was a national park bookstore in the Norris Geyser Basin that sold them.

So after driving there and buying the passport book, we decided to explore a little. One of the first places we came to was Steamboat Geyser, the world's tallest currently-active geyser.

However, it’s very unpredictable and rarely erupts, but we thought we’d hang around for a few minutes anyway. Um, it began to explode out of the blue! It erupted like that for close to an hour. You can hear me telling my wife to be prepared to run at 00:49

Afterwards, when we walked back to our car in the parking lot, our car, along with dozens of others, were coated in a hard mineral film that took quite a lot of effort to clean off (never got 100% of it off - good thing it was a rental car!)
