Fontainebleau boulders helped invent modern climbing styles
Rock climbing ascends natural crags or indoor resin walls, with routes logged in guides and databases noting beta and first ascents. Lines run from a few metres to over 1,000 m high; traverses can stretch 4,500 m. Today free climbing—no upward pull from gear—rules, from boulders to big walls.
Guidebooks and websites log each route’s beta, its sequence of moves, along with the first ascent and the prized first free ascent; step-by-step beta videos have even sparked legal fights between databases. Routes are drawn as topos and gathered on sites such as theCrag.com and MountainProject.com. Worldwide, lead routes are mostly graded on the French numerical or American YDS scales, and boulder problems on V-grades or Font grades.
Early twentieth-century leaders protected themselves by looping the rope over natural spikes while the belayer held it around the waist. Today a belayer locks a mechanical device if the leader falls, and should a piece of traditional gear rip out, the climber keeps dropping until the next holds, a zipper fall. Height adds danger but not necessarily difficulty: climbers have spent years on Burden of Dreams, a route just 4 metres tall.
Granite offers grip and cracks at El Capitan, Joshua Tree and Squamish; limestone gives detailed holds at Malham Cove, Céüse and the Verdon Gorge; sandstone has sculpted forms at Indian Creek, Rocklands and Fontainebleau. The earliest climbs were smooth slabs relying on balance and smearing, as on Britain’s Indian Face, before climbers learned laybacking, bridging and jamming for cracks. Techniques like crimping and gear like sticky rubber, spring-loaded cams and campus boards pushed standards upward, and bolting outdoor routes remains a source of debate.
In 1964 a wall built in a corridor at Leeds University produced students who, trained only indoors, could handle some of Britain’s hardest outdoor climbs, setting off an indoor boom. The MoonBoard has 200 holds allowing more than 50,000 sequences, and women’s lead walls at the 2024 Olympics reached 5.14c, or 8c+.
