Thomas John (Tom) Higgins (born 1944) is a Californian rock climber with many first and first free ascents primarily in the western United States. He is noted for pushing standards using a purist, free climbing style.
He began climbing in the early 1960s with partners Bud (later Ivan) Couch and Russ McLean on the sandstone boulders and short cliffs of Stony Point near Los Angeles. He soon teamed up with lifelong climbing partner Bob Kamps. Together they did the 1963 first free ascent of Blanketty Blank at Tahquitz Rock (5.10c) in Southern California. On this and other routes to follow, they employed ground up climbing without previewing or rehearsing the route or resting on the rope. They also placed protection (including bolts) on lead, all elements of a climbing style now termed Traditional climbing in contrast to Sport climbing. Another notable first ascent at Tahquitz was 1964's Jonah with Mike Cohen and Roy Coats. Near Tahquitz at Joshua Tree, he did the first free ascent of Left Ski Track on Intersection Rock. Done in 1968, the climb is significant for its difficulty rating of 5.11, unusual for the time.
Higgins began climbing in the High Sierra in California with the first ascent of the East Buttress of Agassiz Needle, Temple Crag with Couch; and the North Face of Mt. Morrison with Charlie Raymond. In 1964, Higgins and Couch visited Wales, U.K., and climbed on a borrowed rope and slings threaded with machine nuts as protection with pitons was forbidden in the cliffs. They also climbed in Chamonix, France, where Higgins teamed with English partners to do the first free ascents of the East Face of the Moin, the M Metago Route and Albert West Face.
In the late 60s, Higgins began climbing in Yosemite Valley. With Kamps, he did the first free ascent of the NE Buttress of Middle Cathedral Rock. With Chris Jones, he did the first free of Serenity Crack and other first ascents (Punch Bowl, The Peanut, Owl Roof, The Void among others). He developed his Yosemite crack climbing skills by building and practicing on a wooden, adjustable crack machine.
