Excerpts:
Arizona's rugged natural beauty has been life-changing for generations of Americans, notably Georgia O'Keefe, Frank Lloyd Wright, the Udalls and Aldo Leopold, one of the country's most beloved conservationists.
This year marks the centennial of Leopold discovering a "land ethic" and wilderness vision in the Southwest. To help celebrate his contributions to the modern conservation movement, a variety of programs will be held over Labor Day weekend at Nutrioso in the White Mountains.
