The image shows a plaque mounted on a concrete wall. The plaque is a dark bronze color with a raised silver border. It reads "HOOVER DAM" in large letters at the top, followed by "NAMED IN HONOR OF" in a smaller font. The next line reads "HERBERT CLARK HOOVER" in a larger font, and the final line reads "31st PRESIDENT OF THE UNITED STATES" in the smaller font. Below the text is a seal with the words "U.S. DEPARTMENT OF THE INTERIOR" and "MARCH 3, 1849" inscribed within it. The seal depicts a bison. The background of the image is the plain concrete wall.
