Colorado Prairie. This dramatic landscape was made possible by the perfect alignment of the sunlight, rich, fluffy clouds and a fast approaching storm. I took the photo on a cross-country trip in 2011. I was riveted by how beautiful and threatening the forces of nature can be at once. The small tree standing alone in the vast landscape stands as symbol of how fragile humans are against such forces.
