Thanks Joan for the answer. I wonder what those farmers would do there in this rugged terrain.
Thanks a lot for your interest Wojtek.These huts were used for storing toolsand for cooking and eating and sleeping only occasionally. In those times the farmers were to the field with the horse and cart and remain there all the day. (de sol a sol)(from de sun rising to the sun set) Today only a few number of persons are able to built them.I've posted some more shots in my flickr account in the "pedra seca" set.JR
