A snowmobile guide and his wife build an off-the-grid cabin by the rivers and mountain ranges of their beautiful home state of Wyoming. The build includes a 272-square-foot cabin with a small shop and garage that are all constructed with zero fossil fuels, meaning no gas generators or grid power will be used and all of the heavy lifting will have to be done by hand. The team faces many challenges, including snowdrifts and visits from four-legged neighbors, but the five-week project will prove to be just as grand as the scenery that surrounds it.
