Alligator Reef 4 immerses the viewer in brilliant turquoise water with the distant lighthouse rising delicately near the horizon. Gentle surface patterns fill the foreground, shifting between aqua, blue, and soft reflections of the sky. The small scale of the lighthouse emphasizes the openness of the surrounding sea. Bright, tranquil, and unmistakably tropical, the photograph captures the expansive character of Alligator Reef.
