Unaided?
He had skis!
;-)
If he had even taken a glass of water from the guys at the pole he would have been disqualified.
He (and the other guy) DID have the guys take some photos. I hope that doesn’t count as “aid”. (I’m guessing it didn’t). But - it did save them the trouble of setting up the tripod as they had done all the other days as they documented the trip.
