Photographs taken by MacArthur fellow Robert Adams since the late 1960s have decisively changed the ways many think about the American West. As we enter the 21st century, it is no surprise that environmental urgencies, including his own very deeply felt concerns, have shaped thinking about Adams's art. This volume surveys Adams's work since its beginnings to offer a new, thematic approach to its layered meanings and complexities and includes previously unpublished photographs.
