Yellowstone antiquities

Archaeologists are studying the Indian use of Yellowstone.. Apparently it was quite popular with various tribes in antiquity, and also up until the point they were driven out.

There is no truth to the idea that Native Americans were afraid of the geysers and thermal features.

...

According to Hunts to Die, in his interview with the photographer-ethnographer Edward Curtis, the spirits in the geysers were afraid of people, rather than the other way around.

That sounds exactly right. They seem supernatural, check. They don't hurt you unless you monkey with them, check. But if you watch them, nothing happens. And then, ten minutes after you've left, you hear the geyser again. What else can you conclude?
