Here are a few classic Sheep Camps from the Wyoming Tales and Trails webpage. There are some great photos and some good information on their web page. I personally took a lot of inspiration from these resourceful and low-cost housing solutions.
There’s a lot of other information and photos of western history here too. Have a look around.

Thank you for this web resource, it’s an interesting perspective on US history
Thanks. It is a unique aspect that many don’t know about. Especially the Basque presence in the west.
