Classic Finger Crack on the Second Buttress offers climbers a straightforward yet engaging traditional challenge in the heart of Boulder Canyon. This single-pitch route ascends a sharply defined finger crack that carves its way up the buttress’s main face, demanding steady hands and precise footwork. Starting from the water pipe scramble on class 4 terrain, the approach itself is a brief but focused venture, setting the tone for the climb ahead. You’ll find yourself rising steadily, moving slightly right after the initial scramble before committing to the crack that guides you upward.

The crack’s dimensions favor fingers and small hands, making protection placement critical but manageable—expect an array of stoppers and small cams to secure your anchors. The rock feels solid and textured, offering reliable jams and rests. Once at the top of the gully, a good belay stance awaits, allowing a moment to appreciate the open bowl of the canyon and the surrounding Colorado peaks. The exposure here is moderate, with no wild drops, but the verticality provides a pleasing sense of altitude without feeling intimidating.

This route’s approachable 5.9 rating represents a classic grade that tests technique more than brute strength. The moves flow logically, with no sudden cruxes, but the narrow crack demands attention to finger jams and body positioning. Climbers coming from the more sandbagged Boulder climbing scene may find the grade well-tuned, rewarding patience and careful listening to your gear placements.

Second Buttress itself sits within the legendary Boulder Canyon, a climbing area known for its blend of granite faces and accessible trad lines. The location offers not just climbing but a chance to soak in sweeping views of alder-lined creek beds, pine-scented air, and the endless ridgelines that frame the Front Range. This climb suits those looking to sharpen finger crack skills while experiencing rock that feels alive—held in place by the steady pulse of mountain currents and the occasional call of foothill wildlife.

For gear, bring a selection of small cams and stoppers tailored to finger sizes, as these will provide the critical protection needed for a confident ascent. Footwear with a precise fit is essential to maintain control on the slab sections and tricky jams. Timing your climb for early morning or late afternoon can spare you the intense midday sun, as the route’s aspect rewards cooler hours with pleasant shade and softer rock temperature.

The approach is straightforward but does require attention to footing on loose rock sections during the scramble. Plan for a quick descent either by walking off the top gully or rappelling as necessary, depending on your skill and comfort level. This climb’s accessible location and moderate protection make it a prime choice for trad climbers seeking a focused, memorable outing in Boulder’s classic climbing landscape.
