  • One of the most dynamic, transformative, and potentially dangerous features in North America is also responsible for some of the continent’s most amazing fossil deposits. It’s a supervolcano we now call Yellowstone.

    So I might get to be a fossil? At least my life will be of interest to someone.

    It will cause little damage, because it's a surface Volcano, you can clearly see that.

    I’m so envious! I’ve always wanted to see the archaeological site. I did a presentation about this but never had the chance to see it.

    Might not be evidence of a large herd. Only one example of it...there could be other causes, such as the ash fall itself, causing all rhinos to head for the water.
