Hypotenuse offers a straightforward yet compelling trad experience carved into the rock faces of Nip and Tuck, a lesser-known sector tucked within the rugged Boulder Canyon. This route centers around a prominent left-facing dihedral that rises steeply into a roof, challenging climbers to engage with its unique line. The dihedral’s vertical crack, slender and subtle, invites careful hand jams and delicate foot placements. As you ascend, the rock’s texture under your fingers shifts—from rough granite edges to smoother patches—reminding you to stay focused and adjust your technique. The surrounding rock face bristles with natural character, and occasional sunlight slices through trees, casting sharp contrasts along the wall.

Though short with just one pitch, Hypotenuse demands respect for its gear placements. Protection is limited to very small cams and slings, requiring sharp attention to gear choices. Whether leading or top-rope climbing, you’ll want a rack oriented towards micro pro to stay secure. The approach into Nip and Tuck is accessible, winding through classic Boulder Canyon terrain dotted with pine and scrub oak, bringing riders close to the raw, exposed granite. This route fits well into a day climbing session focused on technical skill sharpening with a modest physical commitment.

For climbers in the 5.9 range eager to practice trad mechanics, Hypotenuse offers a clear movement problem that sharpens crack technique without overwhelming length. The route’s undeniable character comes from its clean groove, the push through the roof at the top demanding a bit of commitment and balance. Putting the climb into context, it rides a little softer than neighboring harder Boulder Canyon lines, making it an approachable test piece when you want to dial in footwork and gear placements while still enjoying quality stone and peaceful canyon surroundings.

In preparation, pack gear suitable for small placements and be ready for some tricky placements under the roof feature. The route’s setting provides comfortable shade during midday, making summer climbs manageable, though spring and fall bring fresher air and quieter crowds. After topping out, a short walk-off leads back to the approach trail, easing the descent with no technical difficulties. Overall, Hypotenuse is a practical and compelling choice for trad climbers hungry to connect with the granite spine of Colorado’s iconic climbing landscape.
