Left Dihedral stands as a striking introduction to the sandstone climbing that defines Colorado National Monument's quieter Side Areas. This two-pitch trad route offers climbers a hands-on encounter with clean finger and hand cracks set within a right-facing dihedral ramp. From the first jamming moves upward, the sandstone’s texture demands both careful placement and confident movement, making it a valuable warmup for those new to the area’s unique rock.

Pitch one eases you into the climb with an engaging 5.8+ rating, presenting frictionful cracks that encourage a smooth flow of jams and rests as you ascend toward a fixed chain anchor. The finger cracks feel alive under your hands, offering steady purchase while the ramp angle invites steady balance and rhythm. Though modest in difficulty, the pitch remains technical enough to sharpen skills crucial to sandstones’ subtle challenges.

The second pitch elevates the experience, pushing into a notably harder technical section, historically graded around 11+/12-. Here, the rock narrows, and placements for protection get thinner, requiring sharp focus and micro gear finesse. This section demands precision and nerves of steel, testing your ability to read the stone and confidently trust smaller gear such as offset micro stoppers alongside a streamlined rack of cams.

The route sits within the arid, sunlit climbs of Colorado National Monument, a less crowded area where climbers can appreciate sweeping canyon views and exposed walls without the bustle of busier spots. The approach is straightforward, accessible via well-maintained trails that wind through rugged desert flora before reaching the heart of the Side Areas. Climbers benefit from early morning starts to beat the heat, especially in warmer months when the sun bakes the rock.

Given its sandstone nature, the climb calls for careful consideration of weather: dryness keeps the rock secure, and any rain can weaken holds and complicate protection placement. For protection, a standard trad rack enhanced with an extra #1 and #1.5 Camalot, plus a #4 cam for larger placements, thoughtfully prepares you for the route’s demands. A 50m rope is needed to reach the rappel-ready fixed anchors at the top.

Left Dihedral is ideal for those aiming to deepen their sandstone trad climbing skills while soaking in the majesty of Colorado’s desert landscapes. It blends an approachable first pitch with a technical second pitch that rewards climbers with a palpable sense of accomplishment and a connection with the rock’s raw essence. Whether you’re shaking off rust or pushing your limits, this route stands as a gateway to the Monument’s unique climbing culture.

Before you head out, pack plenty of water, sturdy footwear with sticky rubber, and layered clothing to adjust for temperature swings. Early spring through late fall works best, avoiding wet conditions that can soften sandstone grips. The descent is a straightforward rappel from the fixed anchors, requiring no additional negotiation beyond focused attention on your rope work and anchor checks.

Overall, Left Dihedral may not boast the flashiest name, but its steady rhythm and reliable gear placements offer a rewarding day in one of Colorado’s most scenic national monuments. This climb teaches respect for the stone’s qualities while uncovering the sheer satisfaction that comes from cracking into solid sandstone with precise, confident jams. Ready your rack and approach the dihedral with intent—adventure and authentic engagement await.
