There's a wealth of information contained & shared that many people never get a chance to experience first-hand. (And, if they did, they probably would be reduced to a quivering mass - myself included.)
There are so many photos of incredible panoramas of vast snow covered expanses, it makes you wonder how someone could willingly - and with complete confidence - just take off into those kinds of conditions. The key, as revealed, is he had years of experience further developing his craft of winter trekking, and was a recognized "stud" amongst his peers.
For instance, Bart designed a lot/most of his gear & equipment - including his specialty skis - and was an early proponent of the functional/multi-purpose UL ethic. Of course, his pack weighed 70lbs, mostly because of materials. There are numerous photos of his long, down overcoat that doubled as his sleeping bag, and his pyramid "tarp" that need only one tie off point to prop it open.
And he got though multiple sub-zero nights in the middle of winter usually above 10k.
