Yosemite, c2002|alt=Steph Davis, far above ground and not attached to a climbing rope, ascends a rock wall using two extended seams within its face. While many rock climbers have free soloed routes (single-pitch or big wall/multi-pitch), at climbing grades well below their ability, a very small minority have practiced free soloing regularly, and at grades closer to their overall limits. The most prominent of this smaller group are those who have broken new grade milestones in free solo climbing and gained a significant profile from their soloing: •
Hansjörg Auer – the prolific big wall and high-altitude big wall free soloist, whose 2007 free solo of
Fish Route on
Marmolada was then the most daring in climbing history. •
Michael Reardon – prolific free soloist whose 2005 free solo of
Romantic Warrior won him
National Geographic's "Adventurer of the Year". •
Alexander Huber – one of the strongest rock climbers of the 1990s who set free solo grade milestones in single-pitch free soloing (with
Kommunist), and big wall free soloing (with the
Brandler-Hasse Direttissima). •
Alain Robert – the early 1990s and 2000s pioneer of
buildering, but who also broke important new free solo grade milestones in the 1990s. •
Wolfgang Güllich – one of the strongest rock climbers of the late 1980s who set free solo milestones (
Weed Killer), and did the iconic solo of
Separate Reality. •
Catherine Destivelle – a leading female climber of the late 1980s, who made iconic free solos in single-pitch (
El Matador), and big wall (
Bonatti Pillar). •
Patrick Edlinger – a leading European free soloist of the 1980s, with iconic big wall free solos in the
Verdon Gorge and
Buoux, as featured in the 1982 climbing film,
La Vie au bout des doigts. • – prolific free soloist whose 1985 free solo of
Revelations jumped several grade milestones in free solo climbing. •
Peter Croft – a prolific Canadian free soloist of the 1980s, who pioneered big wall free soloing with
The Rostrum and
Astroman. •
John Bachar – first free solo "superstar" and prolific American soloist of the late 1970s/early 1980s, who pioneered big wall soloing (
Nabisco Wall). In addition, several other free solo practitioners are considered historically notable in free solo climbing and include the following:
Ron Fawcett, ,
Brad Gobright,
Dan Goodwin,
Colin Haley,
Derek Hersey,
Jimmy Jewell,
John Long,
Dave MacLeod,
Dan Osman,
Dean Potter,
Paul Preuss, and
Tobin Sorenson. Free soloing is less common amongst female rock climbers, however, as well as Catherine Destivelle, the following female climbers are historically notable free solo practitioners:
Steph Davis and
Brette Harrington, both of whom have free soloed single-pitch and big wall routes. ==Evolution of grade milestones==
