Sinusoidal offers a compelling introduction to serious trad climbing on the rugged face of Minkey Wall, set within the Cochrane Lane Cliffs of New Brunswick. This single-pitch route cuts a distinctive path through a sequence of cracks and ledges, challenging climbers to negotiate delicate moves under a looming roof with a large, detached block that demands both respect and steady footwork. From the ground, the wall’s angled lines catch the light differently throughout the day, exposing features that hint at the technical dance ahead. You start left of a substantial hanging block, ascending a system of cracks that widen and shift direction, drawing you toward a unique horizontal seam. Here, the climb veers right in a brief traverse before settling into a left-facing corner—a section that tests your ability to balance power and finesse. The crux unfolds in this corner where a confident move gains a solid stance under the roof, where protection becomes critical.

A bolt placed just beyond the crux signals the transition into the final, slightly overhanging section. Negotiating the small roof requires body tension and precise foot placements, avoiding the unsettling presence of the large but reportedly solid block looming overhead. Above this, the climbing eases into a few more technical moves before reaching the anchor, where a bolted belay secures your return. With gear placements spanning from small cams to larger units (up to #3, with an optional #4 for added security), Sinusoidal leans on careful protection strategy, especially given the scarcity of fixed gear and the PG13 rating, which warns against adventurous moves beyond the bolt.

Accessing the climb involves a straightforward approach through the accessible trails around Welsford, with the crisp latitude and longitude coordinates (45.4396, -66.30719) guiding you to this northern outcrop. The cliff rewards climbers with open views of the surrounding wilderness, where the interplay of wind and shadow adds a dynamic element to the experience. Optimal timing tends toward late spring through early fall, providing stable weather and rock conditions that favor friction and dry holds. Footwear that balances grip with comfort is critical here, while hydration should not be underestimated on exposure days.

Sinusoidal’s appeal lies not only in its technical climbing but in the confidence it builds. It’s a route that encourages thoughtful gear placement and smooth, calculated moves, offering a taste of New Brunswick’s growing climbing landscape. Whether you’re honing advanced crack techniques or seeking a well-protected challenge that blends physical and mental engagement, this route holds steady as a rewarding climb that both welcomes and tests seasoned enthusiasts.
