Biden to propose 20-year drilling ban around Chaco Culture National Historical Park

12. My wife, daughter, and I drove in there in October.

It's about 20 miles of very rough dirt road to get there. But it's worth the drive in.
The cliffs around the canyon have vertical walls comprised of gigantic rocks...they look like stone sentinels.
The ruins themselves are very impressive. Some of the buildings were as much as 5 stories high, and perhaps more than 1000 people lived in the area. Quite an achievement for a supposed primitive people.
I believe it was not just a settlement, but also a spiritual and cultural center that was probably used for ceremonial purposes and training shamans in oral history and healing. Sort of like a university.
