You can see all the pictures of Old Faithful Geyser you want, but the best way to see what’s happening is to watch it in action. We took a few minutes (couple of hours actually) to wait around near Old Faithful in Yellowstone National Park in order to capture a couple of cycles of this iconic geyser.
Here’s a video showing what we saw, along with some of the other features in Yellowstone.
By the way, we spent some time a few years ago learning how a geyser works; what makes it erupt. We then wrote up a post that explains the process the best we could. If you ever wondered what was involved in the mechanics of an erupting geyser, take a look at this post, entitled, “Making a Geyser.”
