Social commentator and preeminent western historian Bernard DeVoto vigorously defended public lands in the West against commercial interests. By the time of his death in 1955, DeVoto had published criticism, history, and fiction. He had won both the Pulitzer and Bancroft prizes. But his most passionate writing—at once incisive and eloquent—advocated conservation of America’s prairies, rangeland, forests, mountains, canyons, and deserts.
