Located on the right flank of the imposing Thunder Ridge wall, "5.8, My Ass" invites climbers to engage with a deceptively demanding route that defies initial expectations. This single-pitch line stretches roughly 80 feet through a delicate face climb that blends technical smearing at the start with thin, precise moves. The lower section challenges you to trust your feet on minimal holds, where the rock seems to test your balance and resolve. As you ascend, three bolts provide critical security before the route transitions into placements for smaller gear, demanding clean and confident protection skills. The wall of Thunder Ridge itself looms with quiet authority, its rough texture gripping the afternoon sun and casting sharp shadows that shift as the day unfolds. It’s a place where the rock speaks in subtle tones, rewarding measured movement and focus. This climb’s 5.9 PG13 rating hints at hidden cruxes that skew the grade upwards — straightforward at first glance but with a punchy challenge that asks you to maintain composure and technique.

To reach "5.8, My Ass," start at the Thunder Ridge parking area, a short but rocky approach trails you into the base of the climb. The path is well-trodden yet demands good footing, winding through sparse pines that whisper in the mountain breeze. This accessibility makes the route a popular choice for climbers looking to push their trad grades without a lengthy hike. The rock’s texture is varied—while the face is smooth and rounded in places, small edges and flakes provide essential incuts when carefully read. Protection consists primarily of fixed bolts early on, transitioning cleanly into smaller cams and nuts whose placements require a practiced eye. For those preparing here, a rack emphasizing small to micro gear will suit the climb best.

The climbing area itself lies in the West Creek sector of the South Platte, Colorado, a region celebrated for its granite features and reliable dry conditions through the spring and fall months. Thunder Ridge offers a rugged playground set against expansive mountain views, with the sun casting warm light on the face in the afternoon, making late day climbs particularly inviting. After topping out, descent is straightforward: a short walk down the accessible talus slopes leads safely back to the trailhead.

Whether you’re stepping up to sharpen your crack skills or to tackle technical face moves, "5.8, My Ass" blends challenge and practicality seamlessly. Approach with solid trad experience, sharp gear placement instincts, and a readiness to engage with the subtle demands of this bright granite wall. It’s a climb that rewards attention to detail and a calm mindset as much as physical strength.
