"Crooked Crack presents a solid single-pitch trad climb within California’s Sierra Eastside, featuring a distinct widening crack that challenges your technique from tight hand jams to wide fists. An excellent route for those looking to sharpen crack skills amidst Mammoth Lakes' high mountain environment."
Crooked Crack offers a straightforward yet engaging trad climb that appeals to both newcomers and seasoned climbers seeking a clean single-pitch route in the Sierra Eastside. As you approach the Main Wall along Crooked Creek, the route's defining feature comes into view: a crooked crack that twists and widens over fifty feet, starting as a demanding tight hand crack before expanding into comfortable wide-fist holds. The rock here is dependable, offering solid friction and a confident grip that invites steady upward movement.
The approach weaves through a blend of pine and juniper, the air thick with the scent of fresh mountain herbs. Sounds of the nearby creek dare you deeper into the wilderness, while the granite wall itself seems alive—challenging your technique with its changing crack sizes and offering occasional rests in large, well-placed huecos. These features create natural breaks and alternate paths around the crack, blending fluid climbing with tactical route-finding.
Equipment needs are practical: finger to large hand-sized cams (.5" to 3") will secure your ascent and protect the varied crack widths. A sturdy anchor set at the route’s summit completes the setup, allowing for a safe top-rope or rappel. The moderate 5.8 rating strikes a balance — firm enough to engage your skills, yet accessible for most climbers familiar with crack techniques.
The climb rewards with views stretching over the rugged landscape of Mammoth Lakes, where granite domes and forested slopes unfold beneath wide skies. Midday climbs benefit from the wall’s east-facing aspect, with crisp morning shade and warming afternoon sun, most enjoyable from late spring through early fall. Be mindful of the narrow trail approaching the wall: boots with solid traction are recommended to navigate loose scree and tree roots.
After topping out, a single rappel or easy downclimb will lead you back to the base, but keep your eyes attentive for slippery patches near shaded rock and loose debris. Local advice emphasizes hydration and sun protection due to the altitude's thin air and variable conditions.
Crooked Crack is a climb that speaks plainly yet memorably through its texture and flow. Whether you’re fine-tuning crack moves or seeking a reliable trad experience in a spectacular setting, this route makes for an adventure that blends technical skill with the crisp mountain air and wide-open views of California’s High Sierra.
Watch for loose rock and debris near the base and during the approach; use caution on the sometimes crumbly ledges around the crack. The rappel descent requires attention to rope drag and stable anchor checks.
Start early to avoid afternoon sun as the wall faces east and becomes warm by midday.
Wear footwear with strong grip to handle the loose approach trail and scree patches.
Hydrate well — altitude and exertion combine to dehydrate quickly in this dry mountain environment.
Check your gear thoroughly; cracks can sometimes trap dirt or small rock shards affecting placements.
Bring a rack of cams from 0.5 to 3 inches to cover the full range of crack widths. A gear anchor is fixed at the top for secure anchoring. Be prepared for both tight jams at the base and wider placements near the top.
