Located within the rugged expanse of California’s Eastern Sierra, Area 13 - Left Side stands as a prime destination for trad climbers seeking steep, varied rock with a blend of challenge and character. Sitting at an elevation just shy of 7,900 feet, this section of the broader Clark Canyon area offers a cool, accessible introduction for climbers drawn to solid granite walls that reward precise footwork and thoughtful protection placement.

Approaching the Left Side is straightforward yet scenic — hikers head up the canyon where the first impressive cliff band comes into view alongside a pumice slope that leads directly to the base. The approach trail is well-defined, giving a sense of anticipation as the cliff’s contours sharpen and the morning light spills onto the warm rock faces. This visibility and ease of access make it an inviting spot for day trips or multi-day excursions.

Area 13 - Left Side’s rock quality is consistently notable. This part of the canyon features clean, well-formed cracks and edges that hold traditionals gear securely, making it a satisfying playground for rack builders and crack lovers alike. Classic climbs like Ugly, Fat, Mean, Come to Mammoth (5.7) carry a storied reputation, offering moderate difficulty with a comfortable exposure that tests form without overwhelming. For those looking to push harder, routes like Borrowing From Tradition (5.10b) and Chapusero (5.11a) provide more technical moves and refined gear placements. Each climb presents a balance of adventure and calculated challenge, drawing climbers who appreciate purposeful movement over pure athleticism.

The overall vibe here leans heavily into the traditional ethos, with a strong sense of quiet focus rather than crowded sport crags. Climbers often find themselves alone or in small groups savoring the sweeping views that stretch across Mammoth’s alpine ridges. On clear days, the glare of sunlight warms the cliff, but early mornings or late afternoons offer cooler temps and softer light, ideal for longer sessions at the base.

Weather patterns tend to favor climbing from late spring to early fall, though the high elevation means sudden shifts are always possible. The rock dries quickly after rain and snowmelt, yet climbers should prepare for occasional afternoon winds and cool evenings. Layered clothing and attention to local forecasts will make your time here more comfortable.

Protection strategy calls for a solid rack of cams and nuts, focusing on mid-size placements with some larger cams to cover the wider sections. The rock demands careful, patient gear placement, rewarding climbers who respect its qualities over aggressive clipping. Helmets are advisable — the approach passes near loose rock areas, and the routes themselves occasionally produce small chips.

Descending is typically simple; most climbs finish at ledges where a walk-off route is available, though some lines require a short rappel. Familiarity with basic anchor building and rappelling techniques streamlines exit and ensures safety.
