Half Dome is a quartz monzonite batholith at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. It stands at nearly 8,800 feet above sea level and is composed of quartz monzonite, an igneous rock that solidified several thousand feet within the Earth. At its core are the remains of a magma chamber that cooled slowly and crystallized beneath the Earth's surface. The solidified magma chamber was then exposed and cut in half by erosion, therefore leading to the geographic name Half Dome.
Friedrich Wolfgang Beckey, known as Fred Beckey, was an American rock climber, mountaineer and book author, who in seven decades of climbing achieved hundreds of first ascents of some of the tallest peaks and most important routes throughout Alaska, the Canadian Rockies and the Pacific Northwest. Among the Fifty Classic Climbs of North America, seven were established by Beckey, often climbing with some of the best known climbers of each generation.
Mount Edith Cavell is a mountain in the Athabasca River and Astoria River valleys of Jasper National Park, and the most prominent peak entirely within Alberta.
El Capitan is a vertical rock formation in Yosemite National Park, on the north side of Yosemite Valley, near its western end. The granite monolith is about 3,000 feet (914 m) from base to summit along its tallest face and is a world-famous location for big wall climbing, including the disciplines of aid climbing, free climbing, and more recently for free solo climbing.

Aid climbing is a form of rock climbing that uses mechanical devices and equipment, such as aiders, for upward momentum. Aid climbing is the opposite of free climbing, which only uses mechanical equipment for protection, but not to assist in upward momentum. "Traditional aid climbing" involves hammering in permanently fixed pitons and bolts, into which aiders are clipped, whereas "clean aid climbing" avoids hammering, using only removable placements.
Clean climbing is rock climbing techniques and equipment which climbers use in order to avoid damage to the rock. These techniques date at least in part from the 1920s and earlier in England, but the term itself may have emerged in about 1970 during the widespread and rapid adoption in the United States and Canada of nuts, and the very similar but often larger hexes, in preference to pitons, which damage rock and are more difficult and time-consuming to install. Pitons were thus eliminated in North America as a primary means of climbing protection in a period of less than three years.
A piton in big wall climbing and in aid climbing is a metal spike that is driven into a crack or seam in the climbing surface using a climbing hammer, and which acts as an anchor for protecting the climber against the consequences of falling or to assist progress in aid climbing. Pitons are equipped with an eye hole or a ring to which a carabiner is attached; the carabiner can then be directly or indirectly connected to a climbing rope.
Steve Roper is a noted climber and historian of the Sierra Nevada in the United States. He along with Allen Steck are the founding editors of the Sierra Club journal Ascent.
Royal Robbins was one of the pioneers of American rock climbing. After learning to climb at Tahquitz Rock, he went on to make first ascents of many big wall routes in Yosemite. As an early proponent of boltless, pitonless clean climbing, he, along with Yvon Chouinard, was instrumental in changing the climbing culture of the late 1960s and early 1970s by encouraging the use and preservation of the natural features of the rock. He went on to become a well-known kayaker.
John Salathé was a Swiss-born American pioneering rock climber, blacksmith, and the inventor of the modern steel piton. In his later years he promoted Christian spiritualism and vegetarianism.
Bob Kamps was an American rock climber whose climbing career spanned five decades. Born in Wisconsin, he began climbing in California in 1955, and was a member of that cadre of Yosemite pioneers who first ascended many of its great walls in the 1950s and 1960s. He was particularly adept on steep rock faces, and was among the first to shift attention from aid climbing to free climbing. Over the years he made more than 3,100 climbs. Many were first ascents or first free ascents.
In the history of rock climbing, the three main sub-disciplines—bouldering, single-pitch climbing, and big wall climbing—can trace their origins to late 19th-century Europe. Bouldering started in Fontainebleau, and was advanced by Pierre Allain in the 1930s, and John Gill in the 1950s. Big wall climbing started in the Dolomites, and was spread across the Alps in the 1930s by climbers such as Emilio Comici and Riccardo Cassin, and in the 1950s by Walter Bonatti, before reaching Yosemite where it was led in the 1950s to 1970s by climbers such as Royal Robbins. Single-pitch climbing started pre-1900 in both the Lake District and in Saxony, and by the late-1970s had spread widely with climbers such as Ron Fawcett (Britain), Bernd Arnold (Germany), Patrick Berhault (France), Ron Kauk and John Bachar (USA).
Thomas John Higgins was an American rock climber with many first and first free ascents primarily in the western United States. He was noted for pushing standards using a purist, free climbing style.
Layton Kor was an American rock climber active in the 1960s, whose first ascents and drive for climbing are well known in the climbing world. His routes included many climbs in Eldorado Canyon, near Boulder, Colorado, The Diamond on Longs Peak, towers in the desert southwest, and Yosemite National Park, among other locations. Notable among his first ascents is the Kor-Ingalls Route on Castleton Tower and The Finger of Fate Route up the Fisher Towers' Titan; both routes are recognized in the historic climbing text Fifty Classic Climbs of North America.
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.
Allen Parker Steck was an American mountaineer and rock climber.
Thomas "Tom" M. Frost was an American rock climber known for big wall climbing first ascents in Yosemite Valley. He was also a photographer and climbing equipment manufacturer. Frost was born in Hollywood, California, and died in Oakdale, California.
Charles Marshall Pratt was an American rock climber known for big wall climbing first ascents in Yosemite Valley. He was also a long-time climbing instructor and mountain guide with Exum Mountain Guides in the Grand Tetons.
Jerry Gallwas is an American rock climber active in the 1950s during the dawn of the Golden Age of Yosemite Rock Climbing. He achieved a number of pioneering first ascents including sandstone spires in the American Southwest, and the first ascent of the Northwest Face of Half Dome with Royal Robbins and Mike Sherrick in 1957. Gallwas made his own heat-treated chrome-molybdenum steel alloy pitons, which contributed to the success of the climb.
