No, we aren’t talking about belly buttons😊
We are talking about volcanoes, or what is left of an old volcano.
‘Devil’s Tower’ in Wyoming is an outie, a solid core plug being all that is left of an old volcano.
‘Hole in the Ground’ in Oregon is an inie, a huge hole from an old volcano that sunk in on itself because it erupted under water…so we were told.
A very simple analysis, but all in all a lesson in how cool Mother Nature is😎
