Charles Dubouloz is not the only one to have taken advantage of the beautiful January anticyclone. From 12 to 16 January, Léo Billon (member of the Groupe Militaire de Haute Montagne) Sébastien Ratel (ex-GMHM) and Benjamin Védrines climbed the Directissime Harlin on the north face of the Eiger, for the first time in alpine style in winter. Rarely climbed, this route, full of history, is the most direct on the north face.
Léo Billon is not at his first trial in the north face of the Eiger. One of the most capable members of the GMHM has put his climbing shoes on the north face of the Eiger several times, taking advantage of the few summer niches where the right side of the face, overhanging, is dry enough to be climbed
