We have one farmer who uses some of our equipment, but he has also had good luck with soil in Fort Collins, CO [1]. He's on a hill though near a lake which might help. He said drainage was important for him.
Vertical farming is a great way to get around issues with soil quality. Especially for winter growing and also reducing the labor associated with planting, weeding, and harvesting. Seriously though, schedule a time to drop by if you're ever up in Laramie. We have a lot of knowledgeable people here who love talking growing! One of my coworkers has also done some good work on the economics or vertical farming (using our equipment mainly, as – well – that's what we know!) [2]. Much of the economics should be comparable on other vertical systems (though, probably less efficient you know ;) ).
Are you a software dev or tech person? Always fun to talk about the combo of farm and tech!

http://aces.nmsu.edu/ces/yard/2007/020307.htmlHigh altitude gardening (e.g., in the mountains) is difficult, but that is more due to the short growing season than the soil.
Last year a random 40-acre hilltop plot at Indian Creek was listed for 30k and finally sold for 15k, which is amazing. Its neighboring 40-acre lot with a view of Bear Lake is currently being sold for 30k. Lots of variances in prices and terrain, including mountain tops. Or at least tall hills, whatever they officially are.
One of the weirdest incentives for me to keep looking is that certain counties in ID don't have building codes: you're on your own. That flexibility cuts both ways, but it means you could make a mud and straw house if you felt like it, without interference. Of course, cabin kits are probably safer and more practical.
We got a whole lotta land up here, and most of it is stuck in the post-lumber slump.
So - why Wyoming? Why don't you go some place with milder weather that isn't a desert like Kansas or Arkansas?
