How Mountain Men Built Log Cabins To Survive Winters At -40°C ?

How did mountain men survive a Rocky Mountain winter with no training, no blueprint, and no way out? This episode follows Osborne Russell and the fur trappers who built raw log cabins by hand in the 1830s—using trade axes, saddle notches, clay daubing, moss chinking, bark roofs, and stone fireplaces—to stay alive in temperatures that plunged to 40 below. From the beaver boom and the rendezvous system to winter camps, food storage, chimney design, and the Native knowledge that made survival possible, this is the forgotten building science behind the first shelters of the American West.
