Beyond the mountains that ring the urban areas of Southern California lies the Hinterland. It is a land of many uses, and one that engenders a full spectrum of perceptions. This mostly desert terrain is a place that accommodates extremes: proving grounds, heavy industry, waste sites, and recreational zones. It tolerates a kind of freedom that expands the margins of society, and is refuge for radical visionaries and rebels, who at times create inspirational monuments of individual endeavor.
