There are many ruins of ancient people in these red cliffs. Part of this 'home' is original, and part has been restored. I can't remember for sure, but I believe these ruins belonged to the Anasazi who lived in this area.
I guess this photo is 'X' rated. I hope no one is offended. Ancient pictographs (painted), and petroglyphs (carved) are common throughout southern Utah's red rock country. These appear next to the dwelling in the above photo.
