Big wall climbing

of The Nose route (VI 5.9 C2) on El Capitan Big wall climbing is rock climbing on large and very sheer / vertical climbing routes that often take a full day, if not several days, of continuous climbing to ascend. Big wall climbing is a form of multi-pitch climbing but there is no definition of how many pitches are needed for a route to be a big wall; a minimum of at least 6–10 pitches (or roughly 300–500 metres) is typically required. Big wall climbing is usually done in pairs as lead climbing, however, due to the length of the climbs, the second climber usually ascends via a fixed rope to save energy and time. Most big wall routes require traditional climbing techniques for climbing protection however some routes have bolted sections (or pitons) like sport climbing routes. Big wall routes have also been free solo climbed. The duration and sustained exposure of big wall climbs require greater equipment—and equipment-handling skills—over and above what is required for multi-pitch routes. Big wall climbers need to be able to haul gear and supplies up the route as they climb (using pulleys and haul bags), ascend on fixed ropes (the non-leading climber), build major anchor points (for hanging belays), hammer-in bolts and pitons as required, and set up portaledges for resting and sleeping. Given the length of the routes, this must happen efficiently. ==Notable walls==

In determining what is a "big wall", there is not only debate about the height requirements but also on whether it includes alpine climbs such as the north faces of the Eiger and the Matterhorn, which also have a lot of snow and ice. • Tre Cime di Lavaredo, Dolomites. The Dolomites were the birthplace of big wall climbing where many important early tools and techniques were developed, and the scene of many milestones by pioneers such as Emilio Comici and Riccardo Cassin, • Mount Asgard and Mount Thor, Baffin Island. In the early 1970s, British big wall climber Doug Scott highlighted the enormous range and scale of big wall climbing possibilities on Baffin Island, and it has been a focus of big wall climbers ever since. • Cerro Torre and Fitz Roy, Patagonia. Cerro Torre is one of the most iconic big walls but also one of the most controversial as a result of Cesare Maestri's dubious 1959 ascent (disproven in 2015), and his 1970 densely-bolted Compressor Route (bolts removed in 2012); its neighbor Fitz Roy also has iconic big wall routes, and both have attracted climbers doing grand-traverses (or enchainments) of their multiple towers. ==History==

, which is 850-metres, 25-pitches, and graded TD (IFAS), 5.9 (American), 5c (French), VI- (UIAA), IV (NCCS). One of the earliest examples of "big wall climbing" dates from 1887 when a 17-year-old Georg Winkler free soloed the Vajolet Towers in the Dolomites. The Dolomites were the birthplace of big wall climbing, and where pioneer Emilio Comici invented many big wall techniques such as aid climbing with multi-step aiders, hanging belays and bivouacs, advanced rope maneuvers, and leading with a trail rope. In 1933, Comici climbed the overhanging north face of the Cima Grande, then the world's hardest big wall route. Other pioneers such as Riccardo Cassin, a leading alpinist, created harder routes and spread big wall techniques across the Alps. In 1957, a team led by Royal Robbins climbed the Northwest Face of Half Dome in Yosemite, ushering in modern American big wall climbing. The development of big wall techniques and tools in the European Alps and Yosemite led to a worldwide search for new big walls. In 1963, a team led by Chris Bonington established the first big wall routes on the Cordillera Paine, Chile and Patagonia, followed closely by new Italian-led routes. In 1972, Doug Scott, and later Charlie Porter, developed big wall routes on Mount Asgard, and highlighted the enormous big wall potential of Baffin Island. In 1976, a British team led by Joe Brown ascended one of the first-ever high-altitude big wall routes with the granite Trango (Nameless) Tower in the Karakoram, Starting about 1910, leading climbers began to fully free-climb major big wall routes. Tita Piaz, Hans Dülfer, Emil Solleder, Gian Battista Vinatzer, Mathias Rebitsch and Frank Sacherer were the most prominent in their respective generations. In 1988, Todd Skinner and Paul Piana freed the Salathe Wall on El Capitan at . During this era, new milestones were also set in big-wall free solo climbing by Alexander Huber, with Brandler-Hasse Direttissima on the Cima Grande in 2012 at , by Hansjörg Auer, with Fish Route on the Marmolada in 2007 at , and by Alex Honnold with Freerider on El Capitan in 2017 at . ==Equipment==

Big wall climbing requires the equipment used in traditional climbing and multi-pitch climbing (but in greater volume as the pitches are of fuller length), as well as specific additional items that are needed for extended multi-day muti-pitch big wall routes, including: Aid-climbing equipment Many big wall climbers carry a set of aid climbing equipment including aiders, daisy chains, pitons (and also angles, knifeblades, copperheads and even bolt kits), a hammer, hooks (and also skyhooks, talon hooks, cam hooks), prusiks, fifi hooks and a chest harness/gear sling. This is because some aid techniques may be required (see Techniques). Anchor equipment The sustained and exposed nature of big walls requires secure anchor points. These can be for creating temporary camps (e.g. from which portledges are suspended), but also for setting up hanging belay systems (including a bosun's chair for comfort), and strong-points for long and complex abseils, pendulums, or tension-traverses (see Techniques). Fixed and static ropes A distinctive aspect of big wall climbing is the need for extra-long fixed or static ropes that are in addition to the standard dynamic ropes (which will also be extra long for big walls) that are used in all lead climbing. Static ropes are used by the non-lead climber to ascend the route using ascenders (i.e. jumaring), while lighter and thinner non-climbing static trail ropes are also used by both climbers to haul up equipment at the end of each pitch, and also to pass equipment between them while climbing (they are not strong enough for climbing). Food and water Water is one of the heaviest elements that the climbers have to carry, and big walls typically require circa 3-4 liters per day per person to be hauled along the route. Mistakes due to dehydration in the sustained and serious environment of big wall climbing can have serious outcomes. Climbers will also need food/energy provisions to sustain them for the ascent, including any unforeseen delays (e.g., getting trapped in bad weather). Other specific items • Haul bags. Due to the level of equipment and supplies needed, heavy-duty haul bags are used extensively in big wall climbing; self-locking rope capture pulleys are used for hauling up these haul bags on static/tag rope lines. • Portaledges and poop tubes. For overnight stays, portaledges are used (including rain shields), as well as bivy bags and sleeping bags. Poop tubes are used for capturing human waste, which is disposed of on completion. • Other clothing. As the climbers are spending long days (and potentially nights) on the route, they will need some basic rain gear and warm jackets; big wall climbers also use kneepads and fingerless gloves (and duct tape) to protect their skin during the extended climbing. ==Techniques==

While the essence of big wall climbing is that of traditional climbing, and particularly multi-pitch climbing, it also uses a number of specific techniques that are important in being able to meet the unique challenges of ascending big wall routes, which include the following: Aid climbing techniques The use of aid-climbing techniques is common in big wall climbing as the scale of the routes mean that some sections may have difficulties that are way beyond the difficulties encountered on the rest of the route. Simul climbing techniques To speed up their ascent on long big-wall routes, some climbing pairs will use simul climbing techniques where both climbers (the lead climber and the belayer) move simultaneously up the route without any need to use pitches per lead climbing. Simul climbing techniques are complex and dangerous, and require significant coordination and trust between the climbers. Using trailing ropes The lead climber may also use an additional trail rope, which is a thinner and lighter static-rope they trail behind as they ascend. It allows them to pass equipment with their belayer below while on the climb (e.g. pieces of aid gear). Once the lead climber has reached the top of the pitch, they anchor their dynamic lead-rope (which the belayer then jumars up on), and can start hauling up equipment with the trail rope. ==Grading==

showing the grades of all 30 pitches of The Shield big-wall route (overall grade 5.8 A3) on El Capitan Big wall climbing is used exclusively in relation to rock climbing. Long rock climbing routes that also have ice or snow, are referred to as alpine climbing. There is overlap in the skill sets, and many famous alpinists such as Walter Bonatti, Catherine Destivelle, and Alexander Huber, were also big wall climbers. The most common grading systems used in big wall climbing are the French, American (also known as the Yosemite Decimal System), and to a lesser extent the UIAA rock climbing grades for free climbing; the A-grade or C-grade systems are used for sections of aid climbing. In addition to the above rock climbing grades (for both free climbing and for aid climbing), a National Climbing Classification System (NCCS) grade is sometimes quoted on North American big-wall (and alpine) climbs, that are described by the American Alpine Club (republished in 2013) as follows: "North American NCCS grades, often called "commitment grades", indicate the time investment in a route for an "average" climbing team": • I and II: "Half a day or less for the technical (5th [i.e. Yosemite Decimal System grade] class) portion of the route". Often listed as "1–3 hours" (for grade I), and "3–5 hours" (for grade II). • III: "Most of a day of roped climbing". Often listed as "5–8 hours". • IV: "A full day of technical climbing". Often listed as "a full day". • V: "Typically requires an overnight on the route, or done fast and free in a day". Often listed as "one very long day or two full days". • VI: "Two or more days of hard climbing". Often listed as "two days to a week". • VII: "Remote walls climbed in alpine style". Often listed as "more than a week in extreme conditions". Because of the great length of big-wall routes, detailed topos are usually provided outlining the grades on each pitch, and the aid climbing versus free climbing options at key sections. For example, one of the most famous big wall routes is the 31-pitch 870-metre route The Nose, on El Capitan, which is graded VI 5.9 C2 as a partial aid climb (mainly due to its roof section), but which is graded VI if climbed completely free. ==Evolution of grade milestones==

The following big wall free climbing redpoints (i.e. no aid) are notable in the evolution of big wall climbing grade milestones and standards from being a skill used in alpine climbing to a standalone sport in its own right; some are at the borderline of being multi-pitch rather than big wall climbs: Repeated in 2016 by Adam Ondra; 8 days. • 2001: '' (500-metres, 10-pitches), Cima Ovest. First-ever big wall redpoint at , by Alexander Huber; repeating it in 2007 to create Pan Aroma'' 8c, Huber found key holds "treated" from a 2005 attempt, and the crux was lined with pegs, which softened grade to 8b/8b+. • 1993: The Nose (870-metres, 31-pitches), El Capitan. Second-ever big wall free climb at , by Lynn Hill (partnered by Brooke Sandahl); it is considered as one of the most important ascents in rock climbing history, and a major milestone in both female and big wall rock climbing; • 1991: Neverending Story (450-metres, 11-pitches), 7th Kirlichspitze, Rätikon. First big wall free climb at , by . • 1989: New Age (150-metres, 5-pitches), 7th Kirlichspitze, Rätikon. First multi-pitch/big wall free climb at , by . • 1988: Via Acacia (330-metres, 9-pitches), 5th Kirlichspitze, Rätikon, Switzerland. First big wall free climb at , by . • 2007: '''' (850-meters, 37-pitches), Marmolada. First-ever big wall free solo at , by Hansjorg Auer; 2 hr, 55 min. • 2005: Romantic Warrior (305-meters, 9-pitches), Needles, California. First-ever big wall free solo at , by Michael Reardon; • 2002: Brandler-Hasse Direttissima (580-meters, 17-pitches), Cima Grande. First-ever big wall free solo at , by Alexander Huber. High-altitude and expedition A number of big wall-free climbs are notable for their high altitude or the remoteness of the expedition: • 2012: Bavarian Direct (700-metres, 28-pitches, 5.13b), on Mount Asgard. First free ascent of the 1997 aid climb by Alexander Huber and Thomas Huber. • 2009: Eternal Flame (650-metres, 24-pitches, 5.13a), on Trango ("Nameless") Tower. First free ascent by Alexander Huber and Thomas Huber of the historic 1989 Güllich, Albert et al. route. ==In film==

A number of notable films have been made focused on big wall climbing including: • El Capitan, a 1978 documentary film about an early ascent of The Nose (VI 5.9 C2) on El Capitan. • Meru, a 2015 documentary film about the ascent of a Himalayan big wall route called the ''Shark's Fin'', • Valley Uprising, a 2014 Amazon Prime documentary film about rock climbing in Yosemite, that includes big wall climbing. • The Dawn Wall, a 2017 Netflix documentary film about Tommy Caldwell and Kevin Jorgeson's ascent of the first-ever big wall route at . • Free Solo, a 2018 Netflix documentary film about Alex Honnold's free solo climb of Freerider on El Capitan. • The Alpinist, a 2021 documentary film about the late Canadian alpinist Marc-André Leclerc, featuring his solo ascent of Torre Egger in Patagonia == See also ==
