Here's an awesome video that was directed my way:
Dean Potter is characterized by creativity, commitment and challenge. He started climbing as a child, with a free solo fall from a stone wall as one of his earliest memories. Since that time, he has speed soloed Half Dome and El Capitan, Cerro Torre, and Fitzroy. He was the first to make a one-day free ascent of El Cap and Half Dome, and a one-day speed linkup of both of those big walls and Mount Watkins, Yosemites third Grade VI wall. He has also established testpiece crack routes in the Utah desert and highball boulder problems in Yosemite.
Dean has walked the longest highlines, often without a safety leash, though he has dedicated over a decade of engineering and testing to create the safest highline systems currently used. Most recently, he has combined BASE jumping skill with highlining and free soloing, using a specially engineered ultralight BASE rig as his backup system.
Dean currently bases out of Yosemite, where he can usually be found on a large piece of granite.
