In 1966, René Arnold and Joseph Graven made the first solo enchainement of the four Matterhorn ridges in 19.5 hours. Beginning at the 3,300m Bossi Bivouac hut, the pair followed the normal route up the Furggen Ridge and then descended the Hornli Ridge. After crossing the Matterhorn Glacier at the base of the north face, they ascended the Zmutt Ridge and then descended the Italian (Lion) Ridge to the village of Breuil. In 1985, Marco Barmasse repeated their achievement, but this time his route included the first solo ascent of the Furggen overhangs. He completed the enchainement, reaching the Abruzzi Hut after 15 hours.
