“Dave Graham sent his hardest problem to date, in Poudre Canyon, a developing area of gneiss boulders about an hour northwest of Fort Collins, Colorado. Circadian Rhythm climbs out of a steep overhang by using dynamic shifts in body weight to move into sidepulls and underclings. The hard section ends with an “all-out” dyno from two crimps, with nothing for the feet except smears on the 70-degree overhang. Graham completed the line on his fifth day of effort. “It´s drop-the-clutch, super-intense crimping — really powerful!” he said. He also added that Circadian Rhythm is likely harder than his Nothin´ But Sunshine (8B+), in Rocky Mountain National Park, which was previously Colorado´s hardest.” Source: R&I
