4. The Revelations

Marty makes a new start in some of Alaska's most unforgiving terrain, but his first solo flight into the Revelation Mountains becomes a dangerous ordeal. In the Cimarron Valley of New Mexico, Kyle Bell helps his son Ben break his first colt, but day one goes terribly wrong. Eustace Conway and his friend Preston set out to build an enormous lumber shed to shelter his newly milled wood from North Carolina's torrential rains, but it quickly proves to be a risky undertaking. And in the Yaak, Tom attempts to preserve a bison hide that can earn him big bucks if his gamble pays off.
