As it became clear that any non-crumbling face could be conquered with sufficient perseverance and bolt-hole drilling, some climbers began searching for El Cap routes that could be climbed either free or with minimal aid. The West Face route was free climbed in 1979 by Ray Jardine and Bill Price; but despite numerous efforts by Jardine and others, The Nose resisted free attempts for another fourteen years. The first free ascent of a main El Cap route, though, was not The Nose, but Salathé Wall. Todd Skinner and Paul Piana made the first free ascent over 9 days in 1988, after 30 days of working the route (graded 5.13b on the Yosemite Decimal System). The Nose was the second major route to be freeclimbed. Two pitches on The Nose blocked efforts to free the route: the Great Roof graded 5.13c and Changing Corners graded 5.14a/b. In 1993, Lynn Hill came close to freeing The Nose, making it past the Great Roof and up to Camp VI without falling, stopped only on Changing Corners by a piton jammed in a critical finger hold. After removing the piton she re-climbed the route from the ground. After 4 days of climbing, Hill reached the summit, making her the first person to free climb The Nose. A year later, Hill returned to free climb The Nose in a day, this time reaching the summit in just 23 hours and setting a new standard for free climbing on El Cap.
