Set against the high-altitude backdrop of Mt Blue Sky, Colorado, Possibility Slab provides a unique climbing experience that demands a thoughtful approach and steady technique. This triangle-shaped slab offers a handful of well-bolted routes, mostly within the challenging 5.10a to 5.11c range, where climbers are called to engage in slabby, technical climbing that tests balance and persistence more than brute strength.

Rising to an elevation of 11,607 feet, Possibility Slab stands out with its carefully handcrafted bolts, each placed by hand drilling — a detail that speaks volumes to the commitment of its developers and the quality of protection found here. Most climbs require a 70 meter rope to complete, as some routes stretch into long, sustained pitches that feel both exposed and exhilarating without being overly committing.

One of the defining features of this area is a remarkable two-pitch route that can be linked into one mega 80m pitch — a continuous slab adventure for those with the stamina and rope length. Classic climbs like Tiny Moving Parts at 5.9 offer a more moderate warm-up, while The Upsides at 5.11c challenges experienced climbers with bold, sustained moves earning a reputation as a stand-out test piece.

Access requires some attention, especially with the Mt Blue Sky Road closure for the 2025 season. All crags here are accessible only by hiking, adding a layer of adventure from the moment you start your approach. Getting to the top involves following cairns from the notch, descending carefully along the rim where anchors await for a pair of 35 meter rappels down to the base. Climbers choosing The Upsides for their exit route will find this descent method preferred, as hiking around the top is described as exhausting and precarious.

The climbing style here prioritizes balance, quiet confidence on slab, and a keen eye for subtle holds. Unlike steep sport walls full of juggy rails, Possibility Slab demands patience and finesse, rewarding those who trust their feet and climbing sense. The rock is mostly featureless once you get into the crux sections, so smooth, deliberate movements are essential.

Seasonally, the area benefits from Colorado’s clearer summer months, though the high elevation means afternoons can bring unpredictable weather. Morning sessions offer the best conditions before any potential thunderstorms build. Expect cool temperatures and dry rock in prime climbing windows.

Gear preparation is straightforward but important — a 70 meter rope is a must due to the length of pitches and rappel stations. Consider a rack focused on sport climbing needs, as all bolts are fixed and well spaced, though attention to clipping on thin slab routes will pay dividends. The rock quality is solid but technical, requiring confident footwork over anything resembling brute force protection.

Locally, it’s wise to be prepared for a strenuous approach with moderate elevation gain and some loose terrain near the rim line. The parking area’s temporary closure means adding time to your hike, so plan accordingly. Early start times are recommended to maximize your climbing day and minimize weather risks.

Possibility Slab stands apart as a place that hones core climbing skills in a quiet alpine setting. With access to some of the most elegant slab climbing on Mt Blue Sky, this venue is perfect for climbers ready to sharpen precision, challenge sustained slab moves, and experience the high country’s raw beauty firsthand. Whether testing yourself on The Upsides or easing into the moderate lines like Tiny Moving Parts, the slab’s hand-drilled bolts and breath-taking setting offer a climbing experience both demanding and rewarding.

For mountaineers and climbers who respect slab climbing’s nuances, Possibility Slab offers a focused, textured adventure with stunning high-elevation views and a commitment to quality craftsmanship in protection placement. It’s an area that asks you to bring your best mental game while delighting those who appreciate technical slabs away from the crowds and the usual climbing corridors.
