I know what you're thinking: "Finally, he gets to Old Faithful!" Well, it did take us until late on our third day at the park to work our way down to its location. Old Faithful is indeed the most famous geyser in Yellowstone National Park, and likely the world. It was named because of its reliable, predictable schedule of eruptions: it shoots off about every 45 to 90 minutes.

This was the first of many Old Faithful eruptions we witnessed, since we were staying in a cabin only a short walk from the geyser. It's never as impressive to see as the first time, but each eruption is a bit different and you really can't help but marvel at something this fantastic occurring so regularly.
