The Salathé Wall is one of the original big wall climbing routes up El Capitan, a 3,000-foot (900 m) high granite monolith in Yosemite National Park. The Salathé Wall was named by Yvon Chouinard in honor of John Salathé, a pioneer of rock climbing in Yosemite. The route is recognized in the historic climbing text Fifty Classic Climbs of North America and is considered a classic around the world.

Big wall climbing is a form of rock climbing that takes place on long multi-pitch routes that normally require a full day, if not several days, to ascend. In addition, big wall routes are typically sustained and exposed, where the climbers remain suspended from the rock face, even sleeping hanging from the face, with limited options to sit down or escape unless they abseil back down the whole route. It is therefore a physically and mentally demanding form of climbing.
