Located in the Black Hills of northeastern Wyoming, Devils Tower National Monument, stands tall against the blue sky. Color photography captures the shadows, formed by the vertical columns of igneous rock, highlighting the grooves on the face of the tower. Loose rocks form a pile near the base of the tower. Pine trees encircle the base as it rises high above the surrounding landscape. A Ponderosa pine tree stands tall in the foreground adding a green contrast against both the tower and a blue sky.
