Bullock found this scene along a California roadway and was drawn to the insight it provides into what goes on in spaces that normally lie beyond our perception. The eroded embankment reveals the slow evolution of the world over the centuries, with organic and inorganic elements coexisting at different stages of growth and decay. Stripped of its skin and flayed by the corrosive force of water, the hill in Erosion reveals a powerfully foreign world as real and beautiful as anything on the surface of the earth. Bullock’s efforts were pointed toward making the ordinary profound and revealing a complexity beyond the surface of things.
