Echinus Geyser, Yellowstone National Park
One time, while visiting Yellowstone National Park, we saw more than a dozen geysers erupt in a single day. This is the Echinus Geyser and many years ago, we saw a very dramatic eruption of this geyser. But not this time. The main difference between a hot spring and a geyser is the explosive nature of the geyser spring. Some of the geysers erupt almost constantly, others only very rarely. The pattern changes over time depending on earthquakes and other changes in the underlying rocks. I don't ever get to spend enough time in Yellowstone National Park. Now, that I live a lot closer, maybe that will change.
