Swimming 140 Mies Across Lake Powell with Shane Schieffer

Shane Schieffer is an endurance swimmer who spent more than 15 years dreaming of a full length swim of Lake Powell, the desert reservoir stretching from Utah into Arizona. In September 2025, he became the first person to complete it, covering 140 miles in 11 days while towing 215 pounds of gear. The route carried him through a remote landscape of sand colored canyons, rock formations, and isolated shorelines.
