Warren Macdonald's life's boundaries were redefined in April 1997 with his accident on North Queensland's (Australia) Hinchinbrook Island. Climbing to the Island's tallest peak, he became trapped beneath a one-ton slab boulder in a freak rock fall. Two days later he was rescued, only to undergo the amputation of both legs at mid thigh.Just ten months later, he climbed Tasmania's Cradle Mountain using a modified wheelchair and the seat of his pants.His first book "A Test of Will" chronicles both the accident and subsequent return to the mountains.In February 2003, he became the first double above-knee amputee to reach the summit of Africa's tallest peak, Mt Kilimanjaro (19,222ft), and more recently, in a spectacular effort requiring more than 2,800 pull-ups over 4 days, created history once again in an ascent of America's tallest cliff face, El Capitan. He is also the only above knee amputee to make an ascent of Canada's landmark frozen waterfall, the 600 ft "Weeping Wall" in Alberta."A Test of Will" is an Australian bestseller and the subject of the "Trapped under a Boulder" episode of the Discovery Channel series "I Shouldn't Be Alive".
