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.

Fifty Classic Climbs of North America is a 1979 climbing guidebook and history written by Steve Roper and Allen Steck. It is considered a classic piece of climbing literature, known to many climbers as simply "The Book", and has served as an inspiration for more recent climbing books, such as Mark Kroese's Fifty Favorite Climbs. Though much of the book's contents are now out of date, it is still recognized as a definitive text which goes beyond the traditional guidebook.

The East Face of Mount Whitney is a technical alpine rock climbing route and is featured in Fifty Classic Climbs of North America. Mount Whitney is the highest peak in the contiguous United States.
The South Face of Charlotte Dome is a technical alpine rock climbing route. It is featured in Fifty Classic Climbs of North America. Chris Jones, a member of the first ascent party, wrote that "in Yosemite, the climb would be recognized as one of the best in the Valley. In the backcountry it will probably remain unknown."
Lost Arrow Spire is a detached pillar in Yosemite National Park, in Yosemite Valley, California, located immediately adjacent to Upper Yosemite Falls. The structure includes the Lost Arrow Spire Chimney route which is recognized in the historic climbing text Fifty Classic Climbs of North America. The spire is the location for a dramatic and famous Tyrolean traverse, which has since become an equally notable slackline.
The Middle Cathedral Rock is a prominent rock face on the south side of Yosemite Valley, California. El Capitan lies due north of Middle Cathedral. Middle Cathedral's East Buttress Route is recognized in the historic climbing text Fifty Classic Climbs of North America.
The Royal Arches Route is a big wall climbing route in California's Yosemite Valley on the Royal Arches wall. The route is recognized in the historic climbing text Fifty Classic Climbs of North America. The route was first climbed Oct. 1936 by Ken Adam, Morgan Harris, K. Kenneth Davis. The route is moderate in difficulty and is frequently climbed. The first 4 pitches are along a west-facing dihedral. At Pitch 5, the route turns north and ascends the main face along crack systems. Pitch 10 can be free climbed at 5.10b however, most climbers use a fixed rope to pendulum to a long ledge. At the end of Pitch 15, begins the bolted rappel route. It is 18 rappels to the Valley floor. Some climbers prefer to continue to "The Jungle" at the end of Pitch 16. Beyond The Jungle is a 5.4 slab and 4th Class scrambling to the Valley Rim. The descent is usually accomplished by traversing northeast to Washington Column and descending the exposed North Dome Gully.

Allen Parker Steck was an American mountaineer and rock climber.
Robert Lindley Murray Underhill was an American mountaineer best known for introducing modern Alpine style rope and belaying techniques to the U.S. climbing community in the late 1920s and early 1930s.
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.
