How are plateaus are formed?
Many plateaus form as magma deep inside the Earth pushes toward the surface but fails to break through the crust. Instead, the magma lifts up the large, flat, impenetrable rock above it. Geologists believe a cushion of magma may have given the Colorado Plateau its final lift beginning about ten million years ago.

If it means anything I am a spheroid earther.

I think a spherical earth had giant trees and giant people at one time. I also think the truth of all this will come out in our lifetime.

Tiiiiiiiiiiiiiiiiiiimmmmmmmmmmmmmbbbbbbbbeeeeeeeeeeeeerrrrr!!

Yeppers!!! When I was a kid, I was there with my Grandpa. I remember him telling me the legend of Devils Tower. He ended it with "just like the tree it used to be".
