In  Dirt Meridian, Andrew Moore turns to the High Plains of North Dakota, South Dakota and Nebraska in a series of stunning, large-format photographs. The Hundredth Meridian, the longitude that neatly divides the U.S. into East and West, traverses America's so-called flyover country, those sparsely populated landscapes between the urban centers on either coast. Other parts of the meridian cross contentious zones such as the heavily fracked Bakken formation in North Dakota.
