The photograph shows a single footprint in a dusty, uneven ground surface. The footprint appears near the center and is oriented diagonally from the lower right toward the upper left. The impression clearly shows the outline of a shoe sole with several horizontal ridges across the interior of the print. The footprint forms a darker recessed area compared with the lighter surrounding ground.Footprint on the Moon from Apollo 11 (NASA, 2015)
