“A Natural History of Washington DC” is a visual poem using images found near, or inspired by, the Hill Center. The parts vary in scale, realism, and in their response to gravity and context. In the spirit of natural history, I am being more of an observer (I just moved to DC) than a story-teller. The central image of the tree was my starting point. Everything grew over time from this Ash on the Hill Center grounds: the fence, the clouds (of Civil War or burning neighborhoods, or just low clouds rendered in paint), the landscape along the lower edge, and the red pyramid which I think of as L’Enfant with his neo-classical plans. The cross-hatching at the top echoes 19th century illustrations, and the blue-green floating blobs are concentrations of green leaves, blue sky, sunlight and inspiration.
