We love our National Parks. It was because of the parks’ exciting capacity to inspire, challenge, and teach that the University of Nevada Press established America’s National Parks books series. In your hands are excerpts about America’s greatest National Parks advocates, these excerpts are from two recent volumes—George Bristol’s Glacier National Park and Don Lago’s Grand Canyon. Like the other books in the series, they are engagingly written, make extensive use of the historical record, do not shy away from these sites’ controversial pasts and contemporary dilemmas, and also locate these special places within the larger context of American environmental culture.
