'Spiral' (2011/12) represents a journey across the USA. Beginning in Passaic, New Jersey and ending at Rozel Point, Great Salt Lake, Utah, 'Spiral' traces a route that echoes the shape of Robert Smithson's 1970 sculpture, 'Spiral Jetty'. From the thirty days' journey, 34 silver gelatin photographs are presented in their order of exposure. The first picture was made in Harrison NJ, a short distance from the sites of Smithson's 'A Tour of the Monuments of Passaic' (1967). The last was made in Corinne UT, a few miles from the 'Spiral Jetty'.
