How did people find roots underneath devils tower (I believe it’s ainchent tree🖋

I believe like an earth quake machine type of thing. But it is so cool. Doesnt the bottom look like a tree stump? Can you imagine the size of it and how far away people could see it? It is amazingly beautiful

Volcano is right

Its not a tree. That would be one massive tree

They didn't. It's an old volcano. They track stuff underground with sonar and other echo location technology.
