Its not just cold as balls in the winter, its also hot as fuck in the summer. Its not called the North American Badlands to make some sort of epic statement. Its literally Bad Land.
40 Acres in West Colorado is not the same thing as 40 acres on the east coast. Shit, I own 1 acre of East Coast, and if I had the time/inclination, I could turn that 1 acre into a very productive orchard/pig farm. Pen the pigs on the quarter acre, use another quarter acre for the house and half an acre for apple trees, squash, etc. You can literally put seeds from the grocery store into the ground here and the plants will grow.
Try doing that shit in Western Colorado. The land is so marginal if you tried to raise more then a few cows on 40 acres and it will turn into the surface of the moon. Which the tranchers discovered with their hundreds of Alpacas. As for plants, good luck getting anything remotely useful to grow on it. The only thing that 40 acres is good for is making sure your neighbors are VERY far away.
