In poor health in the 1980s, Abbey was at one point given a terminal cancer diagnosis and told he had six months to live. The diagnosis proved erroneous, however, and Abbey lived to complete several more books—essay collections and several novels, including the autobiographical The Fool's Progress and the posthumously published Hayduke Lives! (1990, featuring characters from The Monkey Wrench Gang ). Abbey's journals and essays provided material for a steady stream of publications that appeared after his death. Suffering from increasingly serious esophageal bleeding, Abbey laid plans to die in the open, under the desert skies. He and several friends went out into the desert in early March of 1989, but he rallied and was brought back to his cabin in Oracle, Arizona, near Tucson, where he died on March 14, 1989. His friends buried him, illegally, at an unspecified location said to be on federal land, and the legend of his burial, together with the outlaw mystique and the philosophical vigor of his writings, continued to strengthen his reputation in the years after he passed away.
