Mazeno Ridge was first attempted by a French mountaineering team led by Louis Audoubert in 1979 but bad weather prevented them from climbing any but the first Mazeno peak. The English mountaineer Doug Scott made three attempts at traversing the ridge, one being with Sandy Allen in 1992. The third attempt, in 1995, involved Rick Allen, Wojciech Kurtyka and Andrew Lock, while Scott was unwell, and was successful in climbing the first three of the Mazeno peaks.
