In focusing on the site-specific art of Walter De Maria (1935–2013), three crucial periods of his career can be discerned that mobilized abstract geometry and dimensionality as means of exploring the intersections of global politics and imaging. What ties together this body of site-specific work is an insistent exploration of how the plain forms of line, circle, and sphere propagate into physical and social environments. De Maria's most important work poignantly expresses the temporalities embedded within spatial dimension, repeatedly reflecting on and ultimately casting off the possibility of encapsulating earth-based sites through any single image.
