Tucked within the rugged contours of The Polyp, Festering Puss Nodule cuts through the rock with a straightforward, bold crack that stretches the full length of the cliff face. This two-pitch trad route delivers an engaging mixed experience, marked by a standout "bear hug" bulge halfway up the first pitch that commands both technique and composure. The climb begins with a solid rope-length pitch that challenges climbers to work steadily through a wide, hand-sized crack, testing finger jams and delicate foot placements as the wall leans in.

The crux bulge rises unexpectedly, offering a physical and mental obstacle that defines the character of the route—it’s a moment where the rock seems to push back, demanding confident body positioning before allowing upward progress. Climbers will notice the texture of the stone here, providing just enough friction to keep moves controlled but requiring focus to navigate effectively.

Once past the bulge, the line eases into a smoother groove of crack systems before reaching the belay where the second pitch begins. This shorter, approximately 50-foot pitch keeps the rhythm but introduces smaller, more technical jams and subtle shifts in body angle as the route finishes with accessible terrain atop the cliff.

The approach to Festering Puss Nodule is straightforward, entering from the South Platte side near Devil’s Head. Walk-in trails are moderate and offer an early preview of the rugged landscape, threading through pinyon and juniper groves that hum softly with dry mountain air. The rock here has a solid feel, with geology that rewards climbers willing to place their protection carefully and thoughtfully.

For those planning their ascent, a well-rounded rack with several cams in the 1- to 3-inch range will meet the demands of the route’s protection needs. Placement opportunities are solid but demand attention, especially near the crux bulge where the quality of gear placement can make or break the flow of the climb.

Timing your climb late spring through early fall is ideal, as the southeast-facing wall captures the sun’s warmth through much of the day while providing shade during afternoon hours, keeping rock temperatures comfortable.

Festering Puss Nodule holds an understated charm. Its name might raise eyebrows, but the route itself offers a polished, approachable trad experience that suits climbers looking to hone crack skills on reliable stone away from crowded trailheads. Each pitch holds its own flavor of challenge balanced with accessible climbing, creating a satisfying outing framed by high Colorado desert vistas.
