The past is a mysterious place, nowhere so than at Mare Island, a deserted US Naval base that has been shut down since 1996. At its center stands a series of concrete blockhouses, built many years ago to store explosives. They stand like tombs, plants growing out of their tops. This image intends to express a sense of the past – the interplay of light and shadow on the mossy green concrete takes us as far back as we wish to go. The huge trees with peeling trunks offer not only these shadows – their rough textures are a perfect complement to the mossy powder magazines they guard.
