Two men attempt to cross Antarctica solo

The video tutorial covers an Antarctic expedition starting from the Roan Ice Shelf and ending at the Ross Ice Shelf, taking approximately two months. The explorers face harsh conditions, skiing up to 12 hours a day in winds reaching 100 mph. They carry essential equipment like sleeping bags for extreme cold, portable solar panels, and GPS trackers. Additionally, they use Nordic sleds called pulks to transport food, cooking fuel, and camping gear, with skis designed for better traction.
