About Sundance Buttress

Sundance Buttress is the biggest and most remote of Lumpy Ridge's climbing walls — a 700–800-foot south-facing Silver Plume Granite face at the far west end of the ridge, requiring about seven miles of round-trip hiking from the Lumpy Ridge Trailhead. The rock is exceptional: dense 1.4-billion-year-old plutonic granite riddled with the vertical joint systems that give Lumpy its famous crack climbing. Consensus classics: is one of Colorado's great moderate multipitches, first ascended by Layton Kor; Mainliner (5.9, five pitches), Turnkorner (5.10b), and Grapevine (5.8+) round out the tick list; Sundance (5.11c) is the crag testpiece. The long approach filters crowds — Sundance is Lumpy's most committing outing without leaving the trad-cragging zone. Shares Lumpy Ridge's weather cell with The Book (~1km east). **Annual raptor closures typically run February 15 – July 31**; some Sundance routes historically extended into August — check nps.gov/romo before travelling.
