Soloed Piz Badile's north face via the Cassin route.
On August 10, 1993, Alison Hargreaves successfully soloed the north face of Piz Badile via the classic Cassin route, completing the ascent with remarkable speed in just two hours. This climb demonstrated her unparalleled ability to navigate some of the most historically challenging routes in alpine climbing. The Cassin route is notoriously difficult, requiring not only technical skill but also the mental fortitude to persevere through the complexities of the wall.
This achievement was part of her significant endeavor to solo all six great north faces of the Alps. With each climb, Alison advanced toward this ambitious goal, each ascent adding to her burgeoning reputation as a master of high-altitude solo expeditions.
