Great north faces of the Alps

The six great north faces of the Alps are a group of vertical faces in the Swiss, French, and Italian Alps known in mountaineering for their difficulty, danger, and great height. The "Trilogy" is the three hardest of these north faces, being the Eiger, the Grandes Jorasses, and the Matterhorn.

List

The six great north faces are :

Matterhorn, first ascent in August 1931;
Cima Grande di Lavaredo, first ascent in 1933;
Petit Dru, first ascent in 1935;
Piz Badile, first ascent July 1937;
Eiger, first ascent in July 1938;
Grandes Jorasses, first ascent in August 1938.

Trilogy

Three of the six great north faces — the Eiger, the Matterhorn, and the Grandes Jorasses – are considered by climbers to be much harder to climb and are known as 'the Trilogy'.

Milestones and records

Riccardo Cassin and Liugi "Gino" Esposito made the first ascent of two of the faces on both occasions they climbed in a rope of three, accompanied by a third climber.
The first climber to have ascended all six north faces was Gaston Rébuffat, a French alpinist and mountain guide, who chronicled his feat in his 1954 work, Etoiles et Tempêtes.
The first climber to ascend all six north faces in a single year was the Austrian, from the summer of 1961 to the summer of 1962. In 1993 Alison Hargreaves became the first woman to achieve this feat, with a combined time of less than 24 hours.
Ivano Ghirardini was the first person to climb the "Trilogy" in winter, solo, and Catherine Destivelle was the first woman to complete the solo winter trilogy.
With the introduction of the concept of enchainment, the next challenge was to climb all three faces in one outing, a race eventually won by Tomo Česen in 1986 at the age of 26, although nobody witnessed his feat; after that, who achieved the feat between 11–12 March 1987 in a time of 24 hours.
From December 2014 to March 2015, during a project known as "Starlight and Storms", Tom Ballard, the son of Alison Hargreaves, climbed these six north faces solo, being the first person to complete this feat in a single winter season without a support team. A film chronicling this project, Tom, won several awards at international film festivals.
On 15 August 2021, with his ascent of the Petit Dru in 1 hour 43 minutes, the Swiss climber Dani Arnold completed a ten-year project to make the fastest solo speed climb of all six faces. He had previously set speed records on the other five faces, with Ueli Steck's 2015 solo of the Eiger north face the only current faster ascent.
