"Aldo Leopold's legacy has been shifting in recent years, as scholars, environmentalists, and aficionados have reassessed his life and thought a half century after his death in 1948. Most readers familiar with Leopold know him through his posthumously published A Sand County Almanac (1949), a book with spare, sparkling prose and a density of insight unparalleled in American environmental writing. But for those interested in the evolution of Leopold's thought, A Sand County Almanac can be deceptive, as Leopold took some license with the facts of his intellectual maturation. A decade ago, Baird Callicot and Susan Flader did Leopold scholars a great service by collecting his most important essays in The River of the Mother of God and Other Essays by Aldo Leopold (1991), which revealed a more complicated man whose epiphanies were less stark than those described in A Sand County Almanac. The River of the Mother of God remains the best primary-source introduction to Leopold's thought." Sutter
