Southern Sierra, Domelands, Poison Domes, Various Ascents. Over the past three summers, spurred on by Mark Robinson’s persistence and love for steep rock, Steve Offerman, Mark and I established nine new rock climbs, ranging in difficulty from 5.10 to 5.13, on the wildly overhanging east face of the Upper Poison Dome. This is high altitude (9,000’) sport climbing on some of the finest Southern Sierra granite possible. Rock quality matches the best Needles rock. The climbing tends toward bold power moves.
During July of 1994, Cam and Cathy Donnaho, Pancho Dahl and I climbed three new routes on the south face of the Upper Poison Dome (5.10b, 5.9+, 5.10b). The climbing is on quality, water-polished and featured granite. (Reference, Southern Sierra Rock Climbing: Domelands, Moser & Vernon, p.64.)
