As America approaches the 250th anniversary of the Declaration of Independence, This Land traces the dramatic story of how a fragile nation on the Atlantic coast expanded throughout a continent via six defining frontiers that reshaped the nation without end. Blending immersive vérité storytelling with intimate entry, the collection journeys from the Louisiana Purchase and the rise of New York City to the Rocky Mountains, the Sierra Nevada, Alaska, and the contested borderlands of the American Southwest — revealing how ambition, battle, resistance, and energy redrew the American map. Through professional views and the voices of descendants related to those pivotal moments, together with the households of William Clark, Sacagawea, James Monroe, John Brown, Crazy Horse, and Kit Carson, This Land uncovers a historical past that is still deeply contested and continues to form America right this moment.
