Greg Wilken arrives at his final images through a process akin to a fact-finding mission. On these expeditions the artist is motivated by the discovery of a significant historical event or condition which results in research, field explorations, documentation gathering, and the presentation of evidence, usually in the form of framed photographs, films, and custom-made artist books. Taken at face value, it's a fairly simple set of procedures, a way of getting from A to Z, but the resulting works are anything but easy, demanding a cognitive shift from viewers.
