Near Twentynine Palms in Riverside County, California — The American West (Pacific Coastal)
Classic Lines
The climbers' rock formed from molten magma miles below your feet. Squeezed and shaken by earthquakes for millions of years, the granite split and cracked. Mountain uplifting raised the granite close to the Earth's surface. While still underground, water and chemical weathering sculpted the angular granite blocks into their present forms. As the climate grew more arid, erosion exposed the jumbled boulders. Their fantastic shapes have attracted rock climbers from around the world since the 1940s.

Hemingway Buttress offers climbers fine-crack climbs and established descent paths for rappelling. Whimsical route names like Poodles Are People Too, White Lightning, and The Importance of Being Ernest identify seams of the more challenging and popular climbs here.
