Lewis Lloyd and Straton had been two of the very rare women who climbed the Alps and Pyrenees in the 1860s and 70s. In 1869 just four years after it was first climbed they made an unsuccessful attempt on the Matterhorn. In 1870 they became the first women to climb Monte Viso and the following year they made the first ascent of Aiguille du Moine guided by Joseph Simond. The summit is at an altitude of 3,412 m and it requires climbers to abseil on the descent. Lewis Lloyd retired from climbing in 1873, but Straton continued to climb with Jean Charlet and she eventually married him.
