Biologists have long understood that environmental boundaries are corridors full of life. This is where the ecological action is: where species compete, thrive, endure. For this and other reasons many of us have chosen to make California our home, perched as it is on the tectonic edge of North America. In this sense, the geography and geology of our location, be it the great San Andreas fault or the sheer granite face of the Eastern Sierra, demarcate the boundaries of where and how we live our lives. Hopefully my photographs suggest from an aesthetic perspective the meaning of truly living on the edge, here on the rifted eastern arc of the Pacific Ocean.
