When paired with the historic images of 19th and 20th century photographers, Arizona photographer Allen Dutton's modern-day images reveal the changes that have shaped the state's landscape during the past 100-plus years. To illustrate these sometimes drastic, sometimes subtle differences, Allen searched the state to locate the precise spots from which to rephotograph the scenes captured by his predecessors- endeavoring to achieve the same angles, perspectives, and lighting as in the early photographs. The result reveals the consequences of humankind's efforts to tame the stark deserts and rugged mountains of the American West as well as Mother Nature's ability to rebuild and reclaim her own.
