150 years ago in 1871, Liverpudlian Lucy Walker became the first woman to climb the Matterhorn. She not only managed the climb in cumbersome skirts and hobnail boots but also overcame a deeply embedded gender bias in mountaineering, inspiring countless future female alpinists to follow in her footsteps.

This year, Mammut and Swiss Tourism have teamed up to celebrate Lucy's feat as part of the 100% Women Peak Challenge, sending British outdoor adventurer Olivia Jane to the mountain.
