Book of Bones: The Raw Trad Line at Social Platform

Book of Bones unveils itself immediately upon arrival at Social Platform, marked by a prominent dihedral that challenges climbers with honest, hands-on crack climbing. The rock here is rugged, carrying the scars of weather and history — a gritty texture that tests your grip and patience alike. Expect a first bulge that demands an awkward, committed move; pulling past this section calls for careful foot placement and the strategic use of a 5-inch cam to ease the tension. Once over this initial hurdle, the route settles into a lengthy sequence of jamming and stemming that rewards steady technique over brute force.

Though the rock quality includes loose flakes in the crack’s heart, repeated ascents have begun to clean out these sections, promising improvement with each attempt. The line stretches 115 feet of steadfast trad climbing, capped by a two-bolt anchor that offers safe and solid belay options.

Set within the Central Gorge’s Owens River Gorge corridor, this climb provides a raw, straightforward experience for those who value movement and traditional protection over polished holds. Climbers will find the single rack of gear up to 5 inches sufficient, but attention is needed to place pro securely in the less than pristine rock.

Plan your ascent considering that the rock’s patchy nature can challenge your confidence. The approach to Social Platform is manageable, and the area benefits from open exposure, offering sunlit warmth during cooler months. The wall faces east, blending sun and shade that shifts through the day – early climbs can expect cooler, shaded starts, with warmth spreading by late morning.

For safety, assess every placement carefully, especially around the first bulge where the rock shows signs of instability. Loose flakes require a deliberate technique and patience; rushing here can lead to mishaps. Descending is straightforward with a rappel from the two-bolt anchors, but climbers should be prepared for the usual gritty rock dust and ensure their gear is properly cleaned after the climb.

In sum, Book of Bones suits the climber eager for traditional crack climbing with a practical yet gritty edge — a route where the rock’s character is as much a part of the challenge as the moves themselves. Bring solid gear, steady nerves, and an appreciation for the raw side of the Owens River Gorge climbing experience.

Climber Safety

Loose flakes inside the crack can shift unexpectedly, so test every hold and placement before bearing full weight. The first bulge presents the highest risk, requiring careful footwork and secure gear to avoid falls on fragile rock.

Local Tips

Carry a 5-inch cam for the crux bulge protection.

Route Rating

Difficulty
5.9
Quality
Consensus:The 5.9 rating feels fair, though the awkward start through loose flakes adds a subtle complexity that nudges the effort slightly higher than the grade alone might suggest. The steady jams and stems through the remainder reward climbers with solid technique, making it a good challenge for those comfortable on traditional cracks but wanting a straightforward line.

Gear Requirements

A single rack with cams up to 5 inches covers the necessary protection. Two-bolt anchor is fixed and reliable. Expect to place gear cautiously in flaky rock, especially before and through the first bulge.
