- Team Climb-It member, Nick Duttle sends Lung Fish 5.14b/8c. Born without sweat glands, Nick "The Lizard" Duttle has survived a rough life and persevered... now focusing his energies full time on rock climbing. Lung Fish is a true Rifle, Colorado testpiece. Put up by Jeff Webb, this climb has since suffered broken holds increasing the difficulty and the grade from 14a/8b+ to 14b/8c. With two distinct power cruxes checking in at V9 and V11 - Lung Fish is the rig to fire if Rifle is your proving ground. The majority of strongmen agree Lung Fish is one of the if not the hardest line in the canyon. www.climbit.com
