In August 2005, Patagonia Ambassador Dean Potter free-soloed Heaven (5.12d/13a), a 40-foot overhanging crack that starts over 2,500 feet above the Yosemite Valley floor. Heaven was first freed by Ron Kauk in the mid-90s. Other notable Potter free-solos include Separate Reality (5.11d/12a), Astroman (5.11c), and Dog's Roof (5.12b). Dean Potter is the only person to free climb Yosemite's Half Dome and El Cap in a single day. In Patagonia, he made the first ever free solo of the Supercanaleta on Fitz Roy, followed with the Compressor Route on Cerro Torre, becoming the first to solo both peaks.
