Clean Sweep offers a compelling trad experience climbing a striking crack system on Tonnere Tower's rugged face, positioned just right of the second pitch on the classic Stayin' Alive route. This climb rewards traditional gear enthusiasts with sustained crack climbing that demands solid pro placement, technique, and composure. The route begins after a short approach on Stayin' Alive, Face Off, or Nick Of Time, bringing climbers into the heart of Boulder Canyon’s vertical granite. From the second belay anchor 15 feet to the right of Stayin' Alive's pitch two, Clean Sweep ventures right below a small roof before entering a series of cracks that unfold in natural lines.

The crack system itself becomes a playground of contrasts—fingers slide into tight seams while hands jam comfortably in wider sections. The layback near the start offers relief and technique variety before a steep headwall pushes the challenge higher. Here, strategic gear placement is vital; a green Alien fits perfectly in a finger pocket, anchoring a traverse right that transitions into more technical climbing northward. Beyond this flake, the route intensifies as a second steep crack presents the 5.9 crux, demanding precise body positioning and confidence on smaller edges. Protection in this section is excellent but relies on well-placed gear with a #13 Stopper wired nut being a key piece.

Continuing up and right around an airy bulge keeps the adrenaline steady while a purple tricam aids safety in a horizontal quartz crack. The final stretch leads to a large grassy ledge where climbers can catch their breath before the short final steep pitch to the 2-bolt anchor. This endpoint sits just down and right of Stayin’ Alive’s top belay, linking the routes in a climbing conversation across the tower’s face.

The descent asks for two rappels: a 90-foot rappel angling slightly left back to the starting ledge of Clean Sweep, then a further 95-foot drop from Stayin' Alive's top anchor to the ground. Alternatively, experienced parties can opt to descend via Buried Treasure, which offers a different two-rappel route back to the base.

Clean Sweep is more than a single-pitch challenge; it’s a reminder of why bringing a full rack to Tonnere Tower expands climbing options beyond bolts and sport lines. Crack climbers will appreciate the mix of hand jams, finger locks, and laybacks that emphasize gear skills alongside physical effort. The granite here feels alive—sharp edges demand attention, and the cracks seem to guide your hands upward with a quiet insistence.

Practical tips include packing a comprehensive trad rack ranging from finger-sized cams to larger hand and fist pieces, since protection placements vary with some flared sections needing trusted hybrid cams. The anchors are solid 2-bolt setups, but awareness of rock quality and gear placement diligence ensures a safer ascent. Summer and early fall present optimal conditions, as the wall faces east and morning sun hits early, warming the granite but avoiding overheating midday. Approaches remain straightforward from Boulder Canyon trailheads, with well-marked paths and reasonable hiking distances.

Prepare for this climb by hydrating well, wearing climbing shoes suited for crack work, and communicating clearly with your partner for smooth transitions between pitches. Clean Sweep balances the thrill of a technical trad climb with a manageable length of 95 feet, making it an approachable yet rewarding objective for intermediate and confident climbers eager to expand their rack and tap into Boulder Canyon’s trad offerings.
