A guy I know lives on a mesa in southern colorado, and lives in a hogan that he built. pretty dang cool. totally off of the grid. Definitely not easy to get there, but really puts you out in the middle of nowhere. Made me and my lady think about getting some land eventually and doing something similar and just having a cool place you can go every once and a while to decompress
A few picts of his setup here:
