Topographic Architecture of Grandes Jorasses
The Grandes Jorasses, crowning at Pointe Walker at 4,208 meters (13,806 ft), is one of the most celebrated mountain massifs in the European Alps, rising along the Franco-Italian border in the Mont Blanc massif. Its legendary 1,200-meter sheer North Face is revered as one of the Six Great North Faces of the Alps. First climbed directly up the central Walker Spur by Riccardo Cassin in 1938, it witnessed a historic modern milestone in March 2015 when British solo climber Tom Ballard completed his winter solo hexalogy of the Alps.
