Book excerpt: From the north woods of Maine to the cactus-filled deserts of Arizona, America's national monuments include vast lands rivaling the national parks in beauty, diversity, and historical heritage. These critically important landscapes, mostly under the Bureau of Land Management supervision, are often under the radar with limited visitor information available yet offer considerable opportunities for solitude and adventure compared to bustling national parks. The Antiquities Act of 1906 gave Presidents the authority to proclaim national monuments as an expedited way to protect areas of natural or cultural significance. Since then, 16 Presidents have used the Antiquities Act to preserve some of America's most treasured public lands and waters. In 2017, an unprecedented Executive Order was issued questioning these designations by calling for the review of 27 national monuments across 11 states and two oceans, opening the threat of development to vulnerable and irreplaceable natural resources. Our National Monuments introduces these spectacular and unique landscapes, in the first book of its kind. Accompanying the collection of scenic photographs is an invaluable guide including maps of each national monument with carefully selected attractions identified and described based on the author's wide-ranging explorations. Our National Monuments invites readers to experience for themselves these lands and learn about the people and cultures who came before, and to whom these lands are still sacred places. QT Luong is one of the most prolific photographers working in America's public lands and the author of Treasured Lands, the best-selling and acclaimed photography book about the national parks. Combining hundreds of his sumptuously printed photographs with essays from citizen conservation associations caring for these national treasures; including a foreword by former Secretary of the Interior Sally Jewell and photographs of marine national monuments from Ansel Adams award-winning photographer Ian Shive, the comprehensive portrayals of Our National Monuments help readers understand how these essential landscapes are preserving America's past and shaping its future.
