C-Section carves a distinct path deep within the rugged heart of Joshua Tree’s Split Dome, inviting climbers to explore a narrow and demanding chimney that snakes behind the more frequently traveled In and Out and Big Boy alcoves. This single-pitch, 80-foot climb is an intimate excursion where the rock’s angles force you to engage both body and mind, threading through a constricted interior space that doesn’t forgive hesitation. Starting on approachable, mellow rock, the route gradually tightens as you move deeper into the back passage, offering a rare mix of chimney slugging and technical maneuvering. The initial approach up to Gynogroove chimney warms up your muscles, but soon you must squeeze horizontally into an interior chamber that feels as much like a natural cave as it does a climbing challenge. Every move demands thoughtful positioning and a calm resolve—this isn’t a climb for the faint of frame or those averse to claustrophobic cracks.

Protection on C-Section leans heavily on a handful of larger cams, primarily in the 6 to 12-inch range, with medium-sized gear filling the gaps. The need for bigger pieces is crucial; the route’s confined spaces rarely allow for quick gear changes, so choosing the right equipment beforehand can make the difference between a smooth ascent and a frustrating struggle. Both leader and second benefit from a headlamp on this route—light penetrates only partially into the chimney’s gloom, and illumination is a helpful ally navigating the interior room where daylight dims.

The rock around Split Dome is coarse and solid, a tactile surface that demands clean footwork and deliberate hand placements. The climb’s 5.9 PG13 rating hints at a crux that demands respect but won’t overwhelm those with solid trad skills. The chimney’s narrow nature and the required horizontal squeeze push the experience into a specialized category where flexibility and mental focus are as vital as raw strength.

Joshua Tree’s desert climate means early morning starts are essential, especially on shaded faces like the north aspect of Split Dome. The cooler air invigorates your body, and by mid-afternoon, the sun’s shift encourages retreat. The climb’s solitude adds to its charm—beyond the campsite chatter and tourist bustle, C-Section offers a raw experience where the rock almost dares you to move deeper, tighter, and higher.

Accessing C-Section demands a focused approach; from the trailhead, expect roughly 20 minutes of walking over a well-worn path marked by Joshua trees and scattered granite boulders. The trail gains only moderate elevation but requires attention to footing where loose rock collects. GPS coordinates 34.01005, -116.05528 pin the general area, but locating the start chimney involves familiarity with the formations around Gynogroove.

Descent is straightforward from the top of the pitch, with options to downclimb or rappel depending on your team’s confidence and rope setup. Be mindful of the exposed sections and smooth rock slabs that here can turn slick or dangerously sun-baked.

C-Section’s rare combination of chimney climbing and intimate, tight quarters make it a compelling choice for climbers looking to step beyond mainstream Split Dome routes. Preparation, the right gear, and a willingness to embrace the physical and spatial challenges are key to making this venture rewarding and safe.
