Formations of Erasure consisted of a series of photographs of earthworks and land art pieces across the United States, focusing on those that do not have extensive maintenance programs and thus have been altered by time and the elements. Most of the depicted pieces were constructed in the 1970s and, over time, these structures had receded from the pure, intentional form of the artist’s idea, into a new dynamic form that represents a collaboration between humans and the nonhuman world. The exhibition included documentation of works by Michael Heizer, Robert Smithson, Nancy Holt, William Bennett, and James Pierce.
