The Wallsprawl series frames the rapidly changing cultural context of the West. Each Wallsprawl consists of a repeating pattern of aerial photographs depicting fringe areas where wide-open desert meets large-scale urban development. This is the West that Zittel grew up in, where her parents built a house in an isolated area that sixteen years later became a fully developed suburban matrix complete with a shopping mall. Witnessing this rapid takeover of the natural made her view human progress as a sort of parasitic or viral expansion. Similar to actual growth, the Wallsprawls have the capacity to repeat infinitely, folding a single image over into an infinite sprawl.
