Erin Hogan hit the road in her Volkswagen Jetta and headed west from Chicago in search of the monuments of American land art: a salty coil of rocks, four hundred stainless steel poles, a gash in a mesa, four concrete tubes, and military sheds filled with cubes. Her journey took her through the states of Utah, Nevada, New Mexico, Arizona, and Texas. It also took her through the states of anxiety, drunkenness, disorientation, and heat exhaustion. "Spiral Jetta" is a chronicle of this journey. A lapsed art historian and devoted urbanite, Hogan initially sought firsthand experience of the monumental earthworks of the 1970s and '80s - Robert Smithson's "Spiral Jetty", Nancy Holt's "Sun Tunnels", Walter De Maria's "Lightning Field", James Turrell's "Roden Crater", Michael Heizer's "Double Negative", and the contemporary art mecca of Marfa, Texas. Armed with spotty directions, no compass, and less-than-desert-appropriate clothing, she found most of what she was looking for and then some.
