On July 13, 1985, Scott Balcom became the first man in the world to walk across the Lost Arrow Spire Highline. A towering 2890 feet (880 meters), above the valley floor. 22 years and 3 days later, Libby Sauter became the first woman to cross the lost arrow spire highline. This has become the most coveted highline in the world. Congratulations to Libby!
